Is possible to replace texture part?

Yeah here is project source, you need nxPascal to compile. I remembered wrong though, this demo is using framebuffer for realtime texture editing. For that reason it propably can't be pixel-perfect, but it's efficient. May be difficult code to digest, i can only barely keep up with it myself. Material map is a separate dynamic array.

Framebuffer allows things like even rendering actual 3D-models into the texture.
