Ryan Schmidt	6497a53181	ModelingComponents: Add DynamicMeshActor ... - ADynamicMeshActor type has a UDynamicMeshComponent subobject (similar to StaticMeshActor) - Add IPersistentDynamicMeshSource, a ToolTarget Interface for accessing a UDynamicMesh - Add UDynamicMeshComponentToolTarget, a UToolTarget implementing the above as well as various standard interfaces, to allow Tools to operate on an external DynamicMeshComponent - Update UE::ToolTarget:: helper functions that get/commit via DynamicMesh to handle IPersistentDynamicMeshSource directly, instead of going via existing MeshDescription/DynamicMesh interfaces. Add UE::ToolTarget::SetSourceObjectVisible() helper function. - Add support for creating DynamicMeshActors in UCreateMeshObjectTypeProperties and UEditorModelingObjectsCreationAPI - register UDynamicMeshComponentToolTargetFactory in ModelingToolsEditorMode - Rename existing internal ADynamicMeshActor to AOldDynamicMeshActor. Does not appear to be in use and will be removed in a future CL. #rb lonnie.li #rnx #jira none #preflight 60d0effc367e6700014c2e89 [CL 16735093 by Ryan Schmidt in ue5-main branch]	2021-06-21 18:08:56 -04:00
semion piskarev	3cb0babc20	MeshModelingTools: Added tool targets that operate on static and skeletal mesh assets without an underlying component, and refactored to use the same code. Also changed the dynamic mesh shared pointers in the tool targets to be thread safe ones. ... #rb Ryan.Schmidt #jira none #rnx [CL 16615477 by semion piskarev in ue5-main branch]	2021-06-09 19:21:27 -04:00
Ryan Schmidt	75a21c9bb9	ModelingTools: add support for creating Volumes directly from DrawPolygon, DrawRevolve, DrawPolyPath, and AddPrimitive, CombineMeshes, CutMeshWithMesh, PlaneCut, BaseCreateFromSelected Tools. Improve support for Editing volumes, eg handling mesh/volume interactions, and add configurable auto-simplification for volumes to avoid painful Editor hangs. ... - Move ToolTarget implementations, DynamicMeshToVolume to ModelingComponentsEditorOnly module - move VolumeToDynamicMesh, DynamicMeshProvider/Commiter interfaces to ModelingComponents module - Add UCreateMeshObjectTypeProperties property set to expose mesh/volume options - Add FCreateMeshObjectParams::TypeHintClass to allow AVolume type (or other UClass hints) to be passed to creation APIs - Add UE::ToolTarget::ConfigureCreateMeshObjectParams() util function in ModelingToolTargetUtil, tries to determine output type in a FCreateMeshObjectParams based on input ToolTarget - Add UEditorModelingObjectsCreationAPI::CreateVolume() implementation - Add UEditorModelingObjectsCreationAPI::FilterMaterials() that strips out any internal materials and replaces with WorldGridMaterial. This occurs when (eg) subtracting a Volume from a StaticMesh, because the temporary volume mesh gets assigned internal materials, but the Tools don't know this. Use in EditorModelingObjectsCreationAPI when creating new objects. UStaticMeshComponentToolTarget also does this filtering in ::CommitMaterialSetUpdate(). - Add ::ComponentTypeSupportsCollision() function to ComponentCollisionUtil, use to avoid checks/ensures for Volume targets - Add support for automatic mesh simplification in DynamicMeshToVolume. Add CVar to VolumeDynamicMeshToolTarget.h to control max triangle count (default 500). Apply auto-simplify when creating or updating an AVolume. This prevents the Editor from blocking for long periods on meshes that are too high-res for volumes (even 500 is quite high). - DynamicMeshToVolume now emits polygroup-faces that contain holes (ie multiple boundary loops) as a set of triangles, rather than emitting separate overlapping faces for each boundary loop #rb none #rnx #jira none #preflight 60ba50632c42ea0001cb54c5 [CL 16561742 by Ryan Schmidt in ue5-main branch]	2021-06-04 16:04:03 -04:00
