- 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]
