I am an experienced max user but i have never used combustion before. I have project coming up where it would save me a lot of time if i could swap out a texture on a couple faces of an object in combustion rather than having to re render it in 3D. Ive researched a bit about RPF files and im wondering if this is the approach i could take. Is this possible? If so, does anyone have any links or tutorials i could find that would help? Any ideas or suggestions are greatly appreciated.
