Detailed Description

Contains the vertex UVW coordinates for a single texture coordinate channel.

A mesh may define an arbitrary number of UVW coordinate channels. Each channel associates a single UVW coordinate to each vertex in the mesh. Channels are defined by an ID (not an index), and such IDs are defined sparsely - i.e. a mesh may define UVW channels 0,1,5.
