I am moving my discussion here as it is more relevant and may assist future readers.
I have added tags for 2 members who have knowledge in using blender for texturing and may be able to provide insight.
My dilema is I do not know how to get BforArtist 2 (equivalent of blender 2.93 alpha) to change which images the *.mu file looks for to texture parts of a model, without having to use a Hex editor, and as such I am limited to the number of characters the original texture file had as it's title, as I am afraid to change the number as it might damage something. Following OrbitalManeuvers instructions I thought I had found the right section, but even though I edit in program and it looks right, it reverts to the original texture names when exporting as an mu. I am missing something that makes the edit to new texture files permanent. I feel that I have gleaned a lot more about how the texture/shading is handled, but just can't make it stick.
If anyone can help to tutorial how to make it work, it would be appreciated.
