Member Function Documentation

AddInstanceGroup()

FInstanceGroups::FInstanceGroupId FGeometryCollectionISM::AddInstanceGroup	(	int32	InstanceCount,
		TArrayView< const float >	CustomDataFloats
	)

Add a group to the ISM. Returns the group index.

CreateISM()

void FGeometryCollectionISM::CreateISM

(

USceneComponent *

InOwningComponent

)

Create the ISMComponent according to settings on the mesh instance.

InitISM()

void FGeometryCollectionISM::InitISM	(	const FGeometryCollectionStaticMeshInstance &	InMeshInstance,
		bool	bKeepAlive,
		bool	bOverrideTransformUpdates = false
	)

Initialize the ISMComponent according to settings on the mesh instance.

Member Data Documentation

InstanceGroups

FInstanceGroups FGeometryCollectionISM::InstanceGroups
