Detailed Description

An IFF chunk containing a vertex buffer.

A native mesh resource can contain multiple vertex buffers, which are grouped at run-time according to their slot and unit properties. When rendering a single geometry batch, all vertex buffers with the same slot are grouped, the actual combined vertex data is sourced from that group. All so-grouped buffers must contain an identical number of vertices. A specific vertex attribute may only be defined in at most one of the buffers in the group.
