From Human to Animal: Transforming 3D Models with Colors and Texture

I tried to joke in the last post.

Now what I promised to do is a texture in my library. It takes 1 or multiple images with knots or control points on a material.

The example I take in my code is a head model with face points and parts. This model has colorsa and is put on 3d mode of man or woman. Then, I have to change it, for example, to an animal or a teapot.
