Detailed Description

IRdProceduralSkinNormalsStream:

• Specifies vertex skinning normals for normal indices (IRdTriangleNormalsStream) that are calculated in a lazy way - when stream is locked.
• The stream is part of IRdMesh and is stored in custom stream group.
• Stream is identified by STREAMID_NORMALS id.
