Question about uv texture generation.

[zoe2718]

There are serious problems when generating large pose faces' texture.
I runed the demo.py to generate uv texture and textured mesh, the results are as follows：


Why does it look like this in self-occluding regions?
Is it because of the inaccurate shape or orthogonal projection? Or it is the bug of the code?
Thanks！

The texture is sampled from the original image, so invisible (self-occluded) regions will be filled with pixels where the vertices are projected. It is not the bug, or the projector problem.
