hi,
the tokens i use are:
*MESH_NUMTVERTEX // number of Texture coords

*MESH_TVERT // the texture coord

ase files are text files so u can open the with notepad and read them.

thanks !
but i have a problem :
with *MESH_TVERT, there are 3 coordinates of texture but the last is always at 0.0, have i to ignore this coordinate ?
and i have another question :
what is *MESH_TFACE ? what is the difference with *MESH_FACE ?
thanks.

MESH face and mesh vertex store the (x,y,x) coordinates of your geometry

tface and tvertex store the homogeneous coordinates (UV) of your model for texture mapping
hope this helps
