This is a significant overhaul to the Curve Editor used by Sequencer which adds a plugin-based architecture and extensibility. New tools and toolbar buttons can be added to all usages of the curve editor via user plugins, and the different views for data can be created modularly so new implementations of the editor can register their own way of drawing their data and the tools should just work. Additionally, you can now write your own filters to operate on curve editor data for custom implementations of smoothing, key generation, etc.
The curve editor supports three view types by default - an absolute view (default, matches old behavior), a stacked view and a normalized view. Stacked views draw each curve separately (so non-overlapping) and normalized against their own min/max values. The normalized view draws all curves overlapping with each one normalized against its own min/max values.
A tree view has been added to help effectively manage large numbers of curves. Selecting curves in the treeview controls which curves are visible in the view area. The treeview also supports pinning curves. These pinned curves will always be visible regardless of your selection in the tree view.
A transform tool and a retiming tool have been implemented (via a plugin) which is enabled by default. The transform tool allows you to do a marquee selection of keys and then translate and scale the positions of these keys. The retiming tool allows you to create a 1 dimensional lattice to adjust the timing of your keys with a linear falloff between each lattice point. These tools work across multiple views at the same time which is especially useful if you are representing one dimensional data (such as event keys) in a view, as it allows you to adjust this data at the same time as your animation curves. A smoothing filter has been implemented (via a plugin) to allow running highpass and lowpass filters on your keys.
Opening the curve editor in Sequencer/UMG now creates a separate dockable tab which can be resized and docked as desired. A time slider has been added to the Curve Editor which is synchronized to the playback time in Sequencer. This allows you to scrub time in the curve editor without having to find the Sequencer window and adjust time there while looking at your keys and previewing your animation in the viewport at the same time.
Rudimentary support has been added for saving and later restoring a set of curves in your current session. This allows you to do a rudimentary copy/paste of entire curves but can also be useful for saving a curve, making adjustments to it and then deciding you want to go back - simply reapply the saved curve! Each curve added supports an intention name (such as "Location.X" or "FieldOfView"), and these intention names will be used when trying to apply curves. This allows you to reliably take all of the curves of a transform on one object and apply them to another object (and ensure that Location.X gets applied to the new Location.X, etc.) this can be helpful if you have a mixed set of curves buffered (such as a location and a field of view). In the event that no curves match by intention you can store and apply a single curve at a time from any intention to any other intention.
The Curve Asset editors (float, vector and color curve assets) have been changed to use the new editor. They support the same treeviews, filtering and tools that the Sequencer editor does. In addition, the Color Curve asset editor adds an additional view which provides a 1 dimensional gradient editor as an easier way to visualize and edit colors instead of the channels individually.

Sequencer: Added time-warp capabilities to sequences, sub-sections and skeletal animation sections
This is a large suite of changes that are being submitted in bulk for build-health reasons:
Core machinery:
- FMovieSceneNumericVariant: This is the base variant type that represents either a double, or a custom object. It is not much use on its own, but provides the basis for the time-warp variant, and will be the basis for parameterization.
- FMovieSceneTimeWarpVariant: This is a drop in replacement for a double PlayRate/TimeScale UProperty that can now represent a time-warp or play rate curve, a loop, a clamp, or a fixed time. It also provides functionality for remapping time, and inverse remapping time.
- The following interpolation types have been added/improved to add Derivative and Integral functionality
* FConstantValue: Represents a curve of the form y=c
* FLinearInterpolation: Represents a curve of the form y=mx + c
* FQuadraticInterpolation: Represents a curve of the form y=ax^2 + bx + c.
* FCubicInterpolation: Represents a curve of the form y=ax^3 + bx^2 + cx + d.
* FQuarticInterpolation: Represents a curve of the form y=ax^4 + bx^3 + cx^2 + dx + e. Does not support integration.
* FCubicBezierInterpolation now has an AsCubic method that converts it to a cubic polynomial form, which also allows derivative/integral functionality.
- FPiecewiseCurve(Model): A generic read-only piecewise curve implementation and curve editor model. Used to display derivative curves for playrate.
- FMovieSceneTimingParameters: A struct for specifying section timing that simplifies computation of a transform. I wanted to replace all implementations with this but current deprecation mechanisms were prohibitively restrictive. More work will be needed there to remove legacy code.
- FMovieSceneTimeWarpChannel: A new channel type that defines time in one of two domains: PlayRate or Time
Curve Editor: Added the ability to specify custom axes and child curves
- Custom Axes:
* Custom axes can now be assigned to each curve within a view, and the axis defines the scaling for that curve.
* This allows us to have multiple different 'spaces' on the same view that have vastly different scales (for instance, play rate, and tick resolution times)
- Child Curves:
* Child curves are added whenever their parent is added. This allows us to show the derivative of a play rate curve on the curve editor.
Sequencer: Added Owning Object and key offsets to channel meta-data and curve models, made Sequencer key-editors polymorphic,
- New options on channel proxy entries allow us to specify that a channel's keys are relative to their section start time via a key offset
- New options in the curve editor models allow for a non-UMovieSceneSection owner object type

Sequencer: Added time-warp capabilities to sequences, sub-sections and skeletal animation sections
This is a large suite of changes that are being submitted in bulk for build-health reasons:
Core machinery:
- FMovieSceneNumericVariant: This is the base variant type that represents either a double, or a custom object. It is not much use on its own, but provides the basis for the time-warp variant, and will be the basis for parameterization.
- FMovieSceneTimeWarpVariant: This is a drop in replacement for a double PlayRate/TimeScale UProperty that can now represent a time-warp or play rate curve, a loop, a clamp, or a fixed time. It also provides functionality for remapping time, and inverse remapping time.
- The following interpolation types have been added/improved to add Derivative and Integral functionality
* FConstantValue: Represents a curve of the form y=c
* FLinearInterpolation: Represents a curve of the form y=mx + c
* FQuadraticInterpolation: Represents a curve of the form y=ax^2 + bx + c.
* FCubicInterpolation: Represents a curve of the form y=ax^3 + bx^2 + cx + d.
* FQuarticInterpolation: Represents a curve of the form y=ax^4 + bx^3 + cx^2 + dx + e. Does not support integration.
* FCubicBezierInterpolation now has an AsCubic method that converts it to a cubic polynomial form, which also allows derivative/integral functionality.
- FPiecewiseCurve(Model): A generic read-only piecewise curve implementation and curve editor model. Used to display derivative curves for playrate.
- FMovieSceneTimingParameters: A struct for specifying section timing that simplifies computation of a transform. I wanted to replace all implementations with this but current deprecation mechanisms were prohibitively restrictive. More work will be needed there to remove legacy code.
- FMovieSceneTimeWarpChannel: A new channel type that defines time in one of two domains: PlayRate or Time
Curve Editor: Added the ability to specify custom axes and child curves
- Custom Axes:
* Custom axes can now be assigned to each curve within a view, and the axis defines the scaling for that curve.
* This allows us to have multiple different 'spaces' on the same view that have vastly different scales (for instance, play rate, and tick resolution times)
- Child Curves:
* Child curves are added whenever their parent is added. This allows us to show the derivative of a play rate curve on the curve editor.
Sequencer: Added Owning Object and key offsets to channel meta-data and curve models, made Sequencer key-editors polymorphic,
- New options on channel proxy entries allow us to specify that a channel's keys are relative to their section start time via a key offset
- New options in the curve editor models allow for a non-UMovieSceneSection owner object type

This is a significant overhaul to the Curve Editor used by Sequencer which adds a plugin-based architecture and extensibility. New tools and toolbar buttons can be added to all usages of the curve editor via user plugins, and the different views for data can be created modularly so new implementations of the editor can register their own way of drawing their data and the tools should just work. Additionally, you can now write your own filters to operate on curve editor data for custom implementations of smoothing, key generation, etc.
The curve editor supports three view types by default - an absolute view (default, matches old behavior), a stacked view and a normalized view. Stacked views draw each curve separately (so non-overlapping) and normalized against their own min/max values. The normalized view draws all curves overlapping with each one normalized against its own min/max values.
A tree view has been added to help effectively manage large numbers of curves. Selecting curves in the treeview controls which curves are visible in the view area. The treeview also supports pinning curves. These pinned curves will always be visible regardless of your selection in the tree view.
A transform tool and a retiming tool have been implemented (via a plugin) which is enabled by default. The transform tool allows you to do a marquee selection of keys and then translate and scale the positions of these keys. The retiming tool allows you to create a 1 dimensional lattice to adjust the timing of your keys with a linear falloff between each lattice point. These tools work across multiple views at the same time which is especially useful if you are representing one dimensional data (such as event keys) in a view, as it allows you to adjust this data at the same time as your animation curves. A smoothing filter has been implemented (via a plugin) to allow running highpass and lowpass filters on your keys.
Opening the curve editor in Sequencer/UMG now creates a separate dockable tab which can be resized and docked as desired. A time slider has been added to the Curve Editor which is synchronized to the playback time in Sequencer. This allows you to scrub time in the curve editor without having to find the Sequencer window and adjust time there while looking at your keys and previewing your animation in the viewport at the same time.
Rudimentary support has been added for saving and later restoring a set of curves in your current session. This allows you to do a rudimentary copy/paste of entire curves but can also be useful for saving a curve, making adjustments to it and then deciding you want to go back - simply reapply the saved curve! Each curve added supports an intention name (such as "Location.X" or "FieldOfView"), and these intention names will be used when trying to apply curves. This allows you to reliably take all of the curves of a transform on one object and apply them to another object (and ensure that Location.X gets applied to the new Location.X, etc.) this can be helpful if you have a mixed set of curves buffered (such as a location and a field of view). In the event that no curves match by intention you can store and apply a single curve at a time from any intention to any other intention.
The Curve Asset editors (float, vector and color curve assets) have been changed to use the new editor. They support the same treeviews, filtering and tools that the Sequencer editor does. In addition, the Color Curve asset editor adds an additional view which provides a 1 dimensional gradient editor as an easier way to visualize and edit colors instead of the channels individually.

Each curve added supports an intention name (such as "Location.X" or "FieldOfView"), and these intention names will be used when trying to apply curves. This allows you to reliably take all of the curves of a transform on one object and apply them to another object (and ensure that Location.X gets applied to the new Location.X, etc.) this can be helpful if you have a mixed set of curves buffered (such as a location and a field of view). In the event that no curves match by intention you can store and apply a single curve at a time from any intention to any other intention.
The Curve Asset editors (float, vector and color curve assets) have been changed to use the new editor. They support the same treeviews, filtering and tools that the Sequencer editor does. In addition, the Color Curve asset editor adds an additional view which provides a 1 dimensional gradient editor as an easier way to visualize and edit colors instead of the channels individually.

Sequencer: Added time-warp capabilities to sequences, sub-sections and skeletal animation sections
This is a large suite of changes that are being submitted in bulk for build-health reasons:
Core machinery:
- FMovieSceneNumericVariant: This is the base variant type that represents either a double, or a custom object. It is not much use on its own, but provides the basis for the time-warp variant, and will be the basis for parameterization.
- FMovieSceneTimeWarpVariant: This is a drop in replacement for a double PlayRate/TimeScale UProperty that can now represent a time-warp or play rate curve, a loop, a clamp, or a fixed time. It also provides functionality for remapping time, and inverse remapping time.
- The following interpolation types have been added/improved to add Derivative and Integral functionality
* FConstantValue: Represents a curve of the form y=c
* FLinearInterpolation: Represents a curve of the form y=mx + c
* FQuadraticInterpolation: Represents a curve of the form y=ax^2 + bx + c.
* FCubicInterpolation: Represents a curve of the form y=ax^3 + bx^2 + cx + d.
* FQuarticInterpolation: Represents a curve of the form y=ax^4 + bx^3 + cx^2 + dx + e. Does not support integration.
* FCubicBezierInterpolation now has an AsCubic method that converts it to a cubic polynomial form, which also allows derivative/integral functionality.
- FPiecewiseCurve(Model): A generic read-only piecewise curve implementation and curve editor model. Used to display derivative curves for playrate.
- FMovieSceneTimingParameters: A struct for specifying section timing that simplifies computation of a transform. I wanted to replace all implementations with this but current deprecation mechanisms were prohibitively restrictive. More work will be needed there to remove legacy code.
- FMovieSceneTimeWarpChannel: A new channel type that defines time in one of two domains: PlayRate or Time
Curve Editor: Added the ability to specify custom axes and child curves
- Custom Axes:
* Custom axes can now be assigned to each curve within a view, and the axis defines the scaling for that curve.
* This allows us to have multiple different 'spaces' on the same view that have vastly different scales (for instance, play rate, and tick resolution times)
- Child Curves:
* Child curves are added whenever their parent is added. This allows us to show the derivative of a play rate curve on the curve editor.
Sequencer: Added Owning Object and key offsets to channel meta-data and curve models, made Sequencer key-editors polymorphic,
- New options on channel proxy entries allow us to specify that a channel's keys are relative to their section start time via a key offset
- New options in the curve editor models allow for a non-UMovieSceneSection owner object type

Each curve added supports an intention name (such as "Location.X" or "FieldOfView"), and these intention names will be used when trying to apply curves. This allows you to reliably take all of the curves of a transform on one object and apply them to another object (and ensure that Location.X gets applied to the new Location.X, etc.) this can be helpful if you have a mixed set of curves buffered (such as a location and a field of view). In the event that no curves match by intention you can store and apply a single curve at a time from any intention to any other intention.
The Curve Asset editors (float, vector and color curve assets) have been changed to use the new editor. They support the same treeviews, filtering and tools that the Sequencer editor does. In addition, the Color Curve asset editor adds an additional view which provides a 1 dimensional gradient editor as an easier way to visualize and edit colors instead of the channels individually.

This is a significant overhaul to the Curve Editor used by Sequencer which adds a plugin-based architecture and extensibility. New tools and toolbar buttons can be added to all usages of the curve editor via user plugins, and the different views for data can be created modularly so new implementations of the editor can register their own way of drawing their data and the tools should just work. Additionally, you can now write your own filters to operate on curve editor data for custom implementations of smoothing, key generation, etc.
The curve editor supports three view types by default - an absolute view (default, matches old behavior), a stacked view and a normalized view. Stacked views draw each curve separately (so non-overlapping) and normalized against their own min/max values. The normalized view draws all curves overlapping with each one normalized against its own min/max values.
A tree view has been added to help effectively manage large numbers of curves. Selecting curves in the treeview controls which curves are visible in the view area. The treeview also supports pinning curves. These pinned curves will always be visible regardless of your selection in the tree view.
A transform tool and a retiming tool have been implemented (via a plugin) which is enabled by default. The transform tool allows you to do a marquee selection of keys and then translate and scale the positions of these keys. The retiming tool allows you to create a 1 dimensional lattice to adjust the timing of your keys with a linear falloff between each lattice point. These tools work across multiple views at the same time which is especially useful if you are representing one dimensional data (such as event keys) in a view, as it allows you to adjust this data at the same time as your animation curves. A smoothing filter has been implemented (via a plugin) to allow running highpass and lowpass filters on your keys.
Opening the curve editor in Sequencer/UMG now creates a separate dockable tab which can be resized and docked as desired. A time slider has been added to the Curve Editor which is synchronized to the playback time in Sequencer. This allows you to scrub time in the curve editor without having to find the Sequencer window and adjust time there while looking at your keys and previewing your animation in the viewport at the same time.

Sequencer: Added time-warp capabilities to sequences, sub-sections and skeletal animation sections
This is a large suite of changes that are being submitted in bulk for build-health reasons:
Core machinery:
- FMovieSceneNumericVariant: This is the base variant type that represents either a double, or a custom object. It is not much use on its own, but provides the basis for the time-warp variant, and will be the basis for parameterization.
- FMovieSceneTimeWarpVariant: This is a drop in replacement for a double PlayRate/TimeScale UProperty that can now represent a time-warp or play rate curve, a loop, a clamp, or a fixed time. It also provides functionality for remapping time, and inverse remapping time.
- The following interpolation types have been added/improved to add Derivative and Integral functionality
* FConstantValue: Represents a curve of the form y=c
* FLinearInterpolation: Represents a curve of the form y=mx + c
* FQuadraticInterpolation: Represents a curve of the form y=ax^2 + bx + c.
* FCubicInterpolation: Represents a curve of the form y=ax^3 + bx^2 + cx + d.
* FQuarticInterpolation: Represents a curve of the form y=ax^4 + bx^3 + cx^2 + dx + e. Does not support integration.
* FCubicBezierInterpolation now has an AsCubic method that converts it to a cubic polynomial form, which also allows derivative/integral functionality.
- FPiecewiseCurve(Model): A generic read-only piecewise curve implementation and curve editor model. Used to display derivative curves for playrate.
- FMovieSceneTimingParameters: A struct for specifying section timing that simplifies computation of a transform. I wanted to replace all implementations with this but current deprecation mechanisms were prohibitively restrictive. More work will be needed there to remove legacy code.
- FMovieSceneTimeWarpChannel: A new channel type that defines time in one of two domains: PlayRate or Time
Curve Editor: Added the ability to specify custom axes and child curves
- Custom Axes:
* Custom axes can now be assigned to each curve within a view, and the axis defines the scaling for that curve.
* This allows us to have multiple different 'spaces' on the same view that have vastly different scales (for instance, play rate, and tick resolution times)
- Child Curves:
* Child curves are added whenever their parent is added. This allows us to show the derivative of a play rate curve on the curve editor.
Sequencer: Added Owning Object and key offsets to channel meta-data and curve models, made Sequencer key-editors polymorphic,
- New options on channel proxy entries allow us to specify that a channel's keys are relative to their section start time via a key offset
- New options in the curve editor models allow for a non-UMovieSceneSection owner object type

This is a significant overhaul to the Curve Editor used by Sequencer which adds a plugin-based architecture and extensibility. New tools and toolbar buttons can be added to all usages of the curve editor via user plugins, and the different views for data can be created modularly so new implementations of the editor can register their own way of drawing their data and the tools should just work. Additionally, you can now write your own filters to operate on curve editor data for custom implementations of smoothing, key generation, etc.
The curve editor supports three view types by default - an absolute view (default, matches old behavior), a stacked view and a normalized view. Stacked views draw each curve separately (so non-overlapping) and normalized against their own min/max values. The normalized view draws all curves overlapping with each one normalized against its own min/max values.
A tree view has been added to help effectively manage large numbers of curves. Selecting curves in the treeview controls which curves are visible in the view area. The treeview also supports pinning curves. These pinned curves will always be visible regardless of your selection in the tree view.
A transform tool and a retiming tool have been implemented (via a plugin) which is enabled by default. The transform tool allows you to do a marquee selection of keys and then translate and scale the positions of these keys. The retiming tool allows you to create a 1 dimensional lattice to adjust the timing of your keys with a linear falloff between each lattice point. These tools work across multiple views at the same time which is especially useful if you are representing one dimensional data (such as event keys) in a view, as it allows you to adjust this data at the same time as your animation curves. A smoothing filter has been implemented (via a plugin) to allow running highpass and lowpass filters on your keys.
Opening the curve editor in Sequencer/UMG now creates a separate dockable tab which can be resized and docked as desired. A time slider has been added to the Curve Editor which is synchronized to the playback time in Sequencer. This allows you to scrub time in the curve editor without having to find the Sequencer window and adjust time there while looking at your keys and previewing your animation in the viewport at the same time.
Rudimentary support has been added for saving and later restoring a set of curves in your current session. This allows you to do a rudimentary copy/paste of entire curves but can also be useful for saving a curve, making adjustments to it and then deciding you want to go back - simply reapply the saved curve! Each curve added supports an intention name (such as "Location.X" or "FieldOfView"), and these intention names will be used when trying to apply curves. This allows you to reliably take all of the curves of a transform on one object and apply them to another object (and ensure that Location.X gets applied to the new Location.X, etc.) this can be helpful if you have a mixed set of curves buffered (such as a location and a field of view). In the event that no curves match by intention you can store and apply a single curve at a time from any intention to any other intention.
The Curve Asset editors (float, vector and color curve assets) have been changed to use the new editor. They support the same treeviews, filtering and tools that the Sequencer editor does. In addition, the Color Curve asset editor adds an additional view which provides a 1 dimensional gradient editor as an easier way to visualize and edit colors instead of the channels individually.

Sequencer: Added time-warp capabilities to sequences, sub-sections and skeletal animation sections
This is a large suite of changes that are being submitted in bulk for build-health reasons:
Core machinery:
- FMovieSceneNumericVariant: This is the base variant type that represents either a double, or a custom object. It is not much use on its own, but provides the basis for the time-warp variant, and will be the basis for parameterization.
- FMovieSceneTimeWarpVariant: This is a drop in replacement for a double PlayRate/TimeScale UProperty that can now represent a time-warp or play rate curve, a loop, a clamp, or a fixed time. It also provides functionality for remapping time, and inverse remapping time.
- The following interpolation types have been added/improved to add Derivative and Integral functionality
* FConstantValue: Represents a curve of the form y=c
* FLinearInterpolation: Represents a curve of the form y=mx + c
* FQuadraticInterpolation: Represents a curve of the form y=ax^2 + bx + c.
* FCubicInterpolation: Represents a curve of the form y=ax^3 + bx^2 + cx + d.
* FQuarticInterpolation: Represents a curve of the form y=ax^4 + bx^3 + cx^2 + dx + e. Does not support integration.
* FCubicBezierInterpolation now has an AsCubic method that converts it to a cubic polynomial form, which also allows derivative/integral functionality.
- FPiecewiseCurve(Model): A generic read-only piecewise curve implementation and curve editor model. Used to display derivative curves for playrate.
- FMovieSceneTimingParameters: A struct for specifying section timing that simplifies computation of a transform. I wanted to replace all implementations with this but current deprecation mechanisms were prohibitively restrictive. More work will be needed there to remove legacy code.
- FMovieSceneTimeWarpChannel: A new channel type that defines time in one of two domains: PlayRate or Time
Curve Editor: Added the ability to specify custom axes and child curves
- Custom Axes:
* Custom axes can now be assigned to each curve within a view, and the axis defines the scaling for that curve.
* This allows us to have multiple different 'spaces' on the same view that have vastly different scales (for instance, play rate, and tick resolution times)
- Child Curves:
* Child curves are added whenever their parent is added. This allows us to show the derivative of a play rate curve on the curve editor.
Sequencer: Added Owning Object and key offsets to channel meta-data and curve models, made Sequencer key-editors polymorphic,
- New options on channel proxy entries allow us to specify that a channel's keys are relative to their section start time via a key offset
- New options in the curve editor models allow for a non-UMovieSceneSection owner object type

Sequencer: Added time-warp capabilities to sequences, sub-sections and skeletal animation sections
This is a large suite of changes that are being submitted in bulk for build-health reasons:
Core machinery:
- FMovieSceneNumericVariant: This is the base variant type that represents either a double, or a custom object. It is not much use on its own, but provides the basis for the time-warp variant, and will be the basis for parameterization.
- FMovieSceneTimeWarpVariant: This is a drop in replacement for a double PlayRate/TimeScale UProperty that can now represent a time-warp or play rate curve, a loop, a clamp, or a fixed time. It also provides functionality for remapping time, and inverse remapping time.
- The following interpolation types have been added/improved to add Derivative and Integral functionality
* FConstantValue: Represents a curve of the form y=c
* FLinearInterpolation: Represents a curve of the form y=mx + c
* FQuadraticInterpolation: Represents a curve of the form y=ax^2 + bx + c.
* FCubicInterpolation: Represents a curve of the form y=ax^3 + bx^2 + cx + d.
* FQuarticInterpolation: Represents a curve of the form y=ax^4 + bx^3 + cx^2 + dx + e. Does not support integration.
* FCubicBezierInterpolation now has an AsCubic method that converts it to a cubic polynomial form, which also allows derivative/integral functionality.
- FPiecewiseCurve(Model): A generic read-only piecewise curve implementation and curve editor model. Used to display derivative curves for playrate.
- FMovieSceneTimingParameters: A struct for specifying section timing that simplifies computation of a transform. I wanted to replace all implementations with this but current deprecation mechanisms were prohibitively restrictive. More work will be needed there to remove legacy code.
- FMovieSceneTimeWarpChannel: A new channel type that defines time in one of two domains: PlayRate or Time
Curve Editor: Added the ability to specify custom axes and child curves
- Custom Axes:
* Custom axes can now be assigned to each curve within a view, and the axis defines the scaling for that curve.
* This allows us to have multiple different 'spaces' on the same view that have vastly different scales (for instance, play rate, and tick resolution times)
- Child Curves:
* Child curves are added whenever their parent is added. This allows us to show the derivative of a play rate curve on the curve editor.
Sequencer: Added Owning Object and key offsets to channel meta-data and curve models, made Sequencer key-editors polymorphic,
- New options on channel proxy entries allow us to specify that a channel's keys are relative to their section start time via a key offset
- New options in the curve editor models allow for a non-UMovieSceneSection owner object type
