Change 3441680 by Uriel.Doyon
Added units to point light intensity, to allow the user to specify the value in candelas or lumens.
New point light actors now configure the intensity in candelas by default.
Replaced viewport exposure settings by an EV100 slider.
Hidding the tone mapper in the show flag now still applies the exposure.
Added a new AutoExposure method called EV100 which allows to specify :
- MinEV100, MaxEV100
- Calibration Constnat
- Exposure Compensation

Visualize volumetric lightmaps uses 18% grey in lit mode
Change 3636398 by Daniel.Wright
Translucency lighting modes work with Volumetric Lightmaps
* The old Indirect Lighting Cache always interpolated one sample per object, while Volumetric lightmaps operate at the frequency of the Translucency Lighting Mode (per-vertex or per-pixel) so the lighting accuracy is much higher.
* The old ILC always applied the single lighting sample with a per-pixel normal, even in per-vertex lighting modes
* Volumetric PerVertex NonDirectional (cheapest lit translucency) went from 74 instructions down to 42
* Volumetric Directional went from 104 up to 122
Change 3636604 by Chris.Bunner
Added a material translation error on identically named/associated but differently valued parameters as this will cause one of them to be lost during parameter evaluation, the result being "random".

Change 3639916 by Michael.Lentine
Spelling fix.
Change 3640053 by Mark.Satterthwaite
Fix Desktop Forward rendering on Nvidia Metal rendering on macOS by modifying the shader and runtime to treat ForwardLocalLightBuffer data as uint rather than float and invert the use of as*() casts.
Tthis is *necessary* to avoid a bug/limitation of Nvidia's current Metal shader compiler that flushes all denorm values to zero on load from any resource. AMD & iOS Metal only flush-to-zero when sampling from textures and that's what Apple regard as the expected behaviour. I have however asked them to standardise on the D3D behaviour of preserving denorms on all load, move (incl. min/max/as*()-casts) & store operations. This won't happen in the current or imminent OS/Xcode releases.
Now only Intel Metal is broken and their problems run deeper.
#jira UE-48881
Change 3640983 by Olaf.Piesche
Cache the depth buffer collision shader for GPU particles even when simple forward is enabled, as that can be turned off at runtime.
#jira UE-48799
Change 3641480 by Michael.Lentine
Add min16float to FP16Math
Change 3642442 by Mark.Satterthwaite
Fix the native shader libraries again & undo the increase in cook time from changes to the way FShaderCodeLibrary was compiling & deduplicating the shaders.
- Remvoe the single linear array for accumulated shader code: reallocating this is tremendously expensive and will double the time taken to iteratively cook large projects.
- Uncompress the shader data for the native library system so that it actually works again.
- Fix some errant change to the Metal compiler that was trying to wedge the fully compiled library into the single Metal library which is 100% bogus.
#jira UE-49192
Change 3642919 by Chris.Bunner
Reverted unintended changes to material static parameter set serialization.
Bumped material version to force re-serialization.

#tests Ran locally, changes validated by benj
Change 3644203 by Mark.Satterthwaite
Refactor mtlpp a little bit to make the compiler do more of the work & update for all the latest publicly exposed APIs.
Change 3644336 by Mark.Satterthwaite
Ref-count the mtlpp Device object so that it can be the repository for IMP caching - now just have to go through the types created from a specific device and have them keep a reference....
Change 3644431 by Uriel.Doyon
Added a intensity units property, for point lights and spot lights, that can be set to Candelas, Lumens or Unitless (legacy).
The default units value for newly placed point lights and spot lights is configured in the project settings.
Spot lights configured in lumens have their whole luminous energy redirected toward the cone.
This means that changing the outer cone angle, changes the spot light brightness.
New exposure menu that uses an EV100 slider.
New post process settings "camera" tab regrouping : ShutterSpeed, ISO, Aperture and ExposureCompensation.
Post process settings "auto exposure" tab renamed "exposure".
The calibration constant for "Auto Exposure Basic" is now configurable in the advanced tab.
The auto exposure method is renamed "Metering Mode"
New pre-exposure feature that allows the engine to apply the previous frame exposure before writing to the scene color.
This allows the engine to render the scene with similar range than the final color (after exposure), and avoid arithmetic overflow for low precision RT formats.
The amount of exposure applied directly is called pre-exposure, and is compensated by a smaller post-exposure value.
Change 3645098 by Marcus.Wassmer
Don't add meshes twice when in simpleforward

Metal shader files that can serve as extensions to the metal_stdlib rather than trying to wedge even more into the shader compiler. Might as well leverage Metal's C++'ness.
Currently just a skeleton of a buffer type that would better emulate HLSL Buffer<>/RWBuffer<> objects.

Exposed EmissiveBoost, since Lightmass supports Emissive areas on meshes
Change 3650436 by Mark.Satterthwaite
Implemented the necessary extensions for Metal shading language to move lots of complexity out of MetalBackend and into actual shader code to make life *vastly* simpler.
- Full ue4::typed_buffer<T> wrapper type & associated ue4::buffer<>/ue4::buffer_atomic<> API - totally untested but should be functionally equivalent to HLSL Buffer<T>/RWBuffer<T>.
- All the sensible casts I can think of are now defined in ue4_format - any additional ones can just be added. The enurm of formats needs to be exposed to MetalRHI so we upload the correct values, but this should be trivial.
- Added a full series of wrappers around texturecube_array and depthcube_array to insulate code from whether it is backed by a real cube_array or a texture2d_array so we don't have to maintain complicated variants for new/old iOS devices.
- Added implementations for a bunch of annoying HLSL & GLSL intrinsics that were being matched by name + reverse_bits which needs a custom implementation on old shader standards.

DR - vk - Integrate changes: Multiple PSO caches, shared ucode & compression, size reduction up to 80%
Change 3653940 by Daniel.Wright
Moved Volumetric Lightmap textures out of FScene and into FPrecomputedVolumetricLightmapData so their lifetime can match the MapBuildData. This allows tossing the source BulkData in game after RHI texture creation even though switching lighting scenarios does Release/InitializeRenderingResources multiple times.

Fixed HandleLegacyMapBuildData not getting called on P maps loaded in the editor, which apparently was dropped in an integration error, causing all legacy maps (before the BuildData change) to lose their built lighting.

Metal validation checks to test for drawing of the end of a vertex stream as seen in UE-48172 (Landscape Mesh Flickers Rapidly When Using Sculpting Landscape). This is not a fix for that but just a error log to catch the bad draw calls.

Change 3659644 by Mark.Satterthwaite
D3D11 equivalent to 3656341 (only enabled when -d3ddebug is) to validate DrawIndexedPrimitives isn't trying to draw off the end of the instanced vertex streams which has inconsistent (and potentially undefined) behaviour across the various APIs we support. This fires when painting the landscape because the code attempts to render with a FirstInstance value that is as large as the number of elements in the instance-data streams which D3D11 drivers silently fails to render, but which Metal (& probably Vulkan too) will renders as garbage. This pattern is wrong & will be even more dangerous in a Draw*Indirect world.

Reflection Captures support Lighting Scenarios without recapturing
* Reflection Captures are now part of the Map Build
* Modifying a capture in editor will display a preview, but game can only display built captures (black for unbuilt with screen message)
* Reflection Capture build data moved to the BuildData package
* Building lighting / reflection captures no longer dirties ULevels
* Sky lights which capture the scene now work correctly with Lighting Scenarios
* Lighting Scenarios must now be loaded for each time they are made visible (no switching back and forth while keeping both loaded)
Change 3663215 by Mark.Satterthwaite
Initial, incomplete, tool added to mtlpp to help debug macOS Internal Compiler Errors - the mtlpp command-line tool can be fed the debug output from UE4 along with compiler settings to automatically compile shaders and construct the render pipeline that crashes the runtime compiler.
So far only macOS render-pipeline-states are supported currently.

In the prototype Metal stdlib extension library add inline versions of the D3D SM6 "wave" intrinsics that can be expressed in terms of Metal 2.0 simd/quad group operations (macOS=simd, iOS=quad). These are unlikely to be as efficient as direct intrinsics but they should be functionally equivalent.
These functions are not available *yet* as I still need to hook the ue4_stdlib into MetalShaderFormat & MetalRHI.
The following HLSL 6 functions are implemented:
WaveAllBitAnd
WaveAllMax
WaveAllMin
WaveAllBitOr
WaveAllBitXor
WaveAllEqual
WaveAllProduct
WaveAllSum
WaveAllTrue
WaveAnyTrue
WaveBallot
WaveGetLaneCount
WaveGetLaneIndex
WaveOnce
WavePrefixProduct
WavePrefixSum
WaveReadFirstLane
WaveReadLaneAt
The following can't be implemented in Metal as of Metal 2.0 AFAIK:
WaveGetOrderedIndex
WaveIsHelperLane
GlobalOrderedCountIncrement
QuadReadLaneAt
QuadSwapX

3665210 - Invalidate all Metal shaders again to force a recompile to workaround another driver bug.

3667584 Fix black flickering on some materials that use World Position Offset - the Metal sincos intrinsic comes into two flavours for single precision floats and we want the precise version not the fast version. The "cross" implementation needed a few more fma's too and this change has to invalidate Metal shaders again to take effect.
#jira UE-50399
3667805 Changing sincos in Metal fragment shaders had undesirable side-effects - the compiler is now re-associating another floating point operation - so limit the use of precise::sincos to vertex-shaders for now. This fixes the WPO materials without causing any other obvious problems.

Stop trying to be so clever with Metal clip-distances: AMD have a bug in 10.13.0 that means we can only emit one clip-distance value, so simply emit the value with the lowest index (we have handily ordered them by importance!) and let the others become user-interpolators until this bug is resolved in a macOS SU (according to Max@AMD the fix is in, just not in time for 4.18). This means planar reflections will work, VR no-multi-view-fallback will work & layered rendering will work either individually or together - the difference being that on macOS *only* the VR no-multi-view-fallback & layered rendering paths may be slower when combined with the global clip plane.

Fixed/Improved DnD validation between Content Browsers
Dragging assets between Content Browsers now goes through the same common DnD code (DragDropHandler) as dragging assets between the SPathView and SAssetView, and between items within an SAssetView. This also improves the validation of asset/file drops to prevent you dropping assets/files into class paths.

MAJOR FEATURES + CHANGES

Change 3209340 on 2016/11/23 by Ben.Marsh
Convert UE4 codebase to an "include what you use" model - where every header just includes the dependencies it needs, rather than every source file including large monolithic headers like Engine.h and UnrealEd.h.
Measured full rebuild times around 2x faster using XGE on Windows, and improvements of 25% or more for incremental builds and full rebuilds on most other platforms.
* Every header now includes everything it needs to compile.
* There's a CoreMinimal.h header that gets you a set of ubiquitous types from Core (eg. FString, FName, TArray, FVector, etc...). Most headers now include this first.
* There's a CoreTypes.h header that sets up primitive UE4 types and build macros (int32, PLATFORM_WIN64, etc...). All headers in Core include this first, as does CoreMinimal.h.
* Every .cpp file includes its matching .h file first.
* This helps validate that each header is including everything it needs to compile.
* No engine code includes a monolithic header such as Engine.h or UnrealEd.h any more.
* You will get a warning if you try to include one of these from the engine. They still exist for compatibility with game projects and do not produce warnings when included there.
* There have only been minor changes to our internal games down to accommodate these changes. The intent is for this to be as seamless as possible.
* No engine code explicitly includes a precompiled header any more.
* We still use PCHs, but they're force-included on the compiler command line by UnrealBuildTool instead. This lets us tune what they contain without breaking any existing include dependencies.
* PCHs are generated by a tool to get a statistical amount of coverage for the source files using it, and I've seeded the new shared PCHs to contain any header included by > 15% of source files.
Tool used to generate this transform is at Engine\Source\Programs\IncludeTool.
[CL 3209342 by Ben Marsh in Main branch]
The display name, filter string, and tooltips for the property editor (and associated detail customizations) are now stored as FText rather than FString. This allows us to remove SLATE_TEXT_ARGUMENT from the detail customization widgets.
