   correct texture coordinates from model
  Well, since OpenGL uses a single index for al diferent element atributes (position, texture coordinates, color, normals, etc) what can I do to make models in 3dMax that respect opengl requirements?   
  Your 3dsMax exporter should duplicate those vertices where different attributes are used at the same position.   ;  That works great for fewer position vertex than texture vertex but when a single position vertex have multiple texture vertex?   ;  That's the case I was talking about - there's multiple attributes (tex coords) at the same position.If there's a position used with 2 tex coords, call it V(P1,T1,T2), then you create two vertices V1(P1,T1) and V2(P1,T2)   ;  Oh, thanks!Sounds logical now, :DThank you very much.
