How to make the texture image?

[zhwang-hzau]

Hi, in the free dataset demo: 'rp_dennis_posed_004_OBJ' you provided, it provides a texture image 'rp_dennis_posed_004_dif_2k.jpg' for training or testing, but how can I generate a similar texture image from my own 3D samples for training purposes? I would be very grateful if you could answer me!

@zhwang-hzau Hi, I want to get the uv-map and texture too. How did you solve the problem?
