How to get texture?

[pengzhao-life]

Hi, thanks for sharing the great work! In the result .obj file, I don't see 'vt' for texture. Can anyone help me understand how to get the texture?
One more question: in the code, it seems that outputs are vertices only, and then the pre-defined faces are vertically stacked after all the vertices. So only vertices for the initial output? And how the faces were defined?
Thanks!
