Syntax

struct FGeometryCollectionMeshGroup

Remarks

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.

Variables

	Type	Name	Description
	TMap< FGeometryCollectionStaticMeshInstance, FMeshId >	Meshes	Map from mesh instance description to the its index in the MeshInfo array.
	TArray< FGeometryCollectionMeshInfo >	MeshInfos	Array of allocated mesh infos.

Functions

Type	Name	Description
FMeshId	AddMesh ( const FGeometryCollectionStaticMeshInstance& MeshInstance, int32 InstanceCount, const FGeometryCollectionMeshInfo& ISMInstanceInfo )	Adds a new mesh with instance count.
