Syntax

template<typename ParentType>  
class TDynamicVertexSkinWeightsAttribute : public UE::Geometry::TDynamicAttributeBase< ParentType >

Remarks

Forward declarations

TDynamicVertexAttribute provides per-vertex storage of bone weights (skin weights)

Variables

  Type Name Description
Protected variable ParentType * Parent The parent object (e.g. mesh, point set) this attribute belongs to
Protected variable TDynamicVector< FBoneWeights > VertexBoneWeights FIXME: Replace with a local slab allocator storage to avoid per-item TInlineAllocator.
