Vertex/Face colors in 3DStudio ASC/ASE files ?

[byaniv]

Where in those file-formats is the color codes hidden ?
What's the AB BC CA in the faces' data ?

AB, BC and CA tells you what direction the polygon is facing. A polygon has three sides, called A, B and C. AB=1 means the side is going from A to B. AB=0 means the side is going from B to A. Same thing with BC and CA.

It's more or less a way to define if vertices is specified CW or CCW. You don't have to worry about them.
