    public INodeMappingProviderInterface

Remarks

SkeletalMesh is geometry bound to a hierarchical skeleton of bones which can be animated for the purpose of deforming the mesh. Skeletal Meshes are built up of two parts; a set of polygons composed to make up the surface of the mesh, and a hierarchical skeleton which can be used to animate the polygons. The 3D models, rigging, and animations are created in an external modeling and animation application (3DSMax, Maya, Softimage, etc).

Variables

uint8: 1	bSupportRayTracing	If true, a ray tracing acceleration structure will be built for this mesh and it may be used in ray tracing effects

Deprecated Functions

		Name	Description
	UBodySetup &...	GetBodySetup()	Please do not use this non const function; use the combination of USkeletalMesh::CreateBodySetup() and USkeletalMesh::GetBodySetup() const. Cast the skeletal mesh caller to const to force the compiler to use the USkeletalMesh::GetBodySetup() const function and avoid the deprecation warning
