A few programs when exporting their figures as .obj files also create a file with the
extension .mtl
I would hazard a guess to say that these are the materials that the program used.
Is it possible for a program such as zbrush to access these files and readjust them.
Or failing that ,to convert them to bitmap files.
I have the feeling they are worthless when looked upon from a “readjusting” of textures
point of view
Thank you
