Detailed Description

A mesh group which is a collection of meshes and their related FGeometryCollectionMeshInfo. We group these with a single handle with the expectation that a client will want to own multiple meshs and release them together.

Member Function Documentation

AddMesh()

FGeometryCollectionMeshGroup::FMeshId FGeometryCollectionMeshGroup::AddMesh	(	const FGeometryCollectionStaticMeshInstance &	MeshInstance,
		int32	InstanceCount,
		const FGeometryCollectionMeshInfo &	ISMInstanceInfo,
		TArrayView< const float >	CustomDataFloats
	)

Adds a new mesh with instance count. We expect to only add a unique mesh instance once to each group. Returns a ID that can be used to update the instances.

BatchUpdateInstanceCustomData()

void FGeometryCollectionMeshGroup::BatchUpdateInstanceCustomData	(	FGeometryCollectionISMPool &	ISMPool,
		int32	CustomFloatIndex,
		float	CustomFloatValue
	)

BatchUpdateInstancesTransforms()

bool FGeometryCollectionMeshGroup::BatchUpdateInstancesTransforms	(	FGeometryCollectionISMPool &	ISMPool,
		FMeshId	MeshId,
		int32	StartInstanceIndex,
		TArrayView< const FTransform >	NewInstancesTransforms,
		bool	bWorldSpace,
		bool	bMarkRenderStateDirty,
		bool	bTeleport
	)

Update instance transforms for a group of instances.

RemoveAllMeshes()

void FGeometryCollectionMeshGroup::RemoveAllMeshes

(

FGeometryCollectionISMPool &

ISMPool

)

Remove all of our managed meshes and associated instances.

Member Data Documentation

bAllowPerInstanceRemoval

bool FGeometryCollectionMeshGroup::bAllowPerInstanceRemoval = false

Flag for whether we allow removal of instances when transform scale is set to zero.

MeshInfos

TArray<FGeometryCollectionMeshInfo> FGeometryCollectionMeshGroup::MeshInfos

Array of allocated mesh infos.
