I juste would like a thing...
I made a cube in 3DSMax, with just a color, no texture. I've seen in the DirectX user guide that textures coords are used only when a texture is define.
So, why the textures coords are define in the DAE file after export? for what that is used?
Because after parsing, I have to test each vertex if he a same (only position and normals) is present to know is a have to create a new vertex or just specify an index of an already exiting, and it is very low...
