How do texture coordinates work?

Is there a one-to-one relationship to mesh vertices?

Mapping coordinates (UVW coordinates and the related vertex colors) in 3ds Max are stored in Texture Vertices resp. Color Vertices which can have a completely different count from the mesh vertex count. Understanding the relationships between texture coordinates and the mesh they are applied to is crucial.

The following chapter explains the way texture coordinates work inside of 3ds Max.

The following topics provide information about accessing and manipulating texture coordinates and vertex color data.
