Take a model. For example 'F1 Car' that comes with DarkMATTER it renders in a nice yellow/black with DarkMATTER written down the side of it.
Now supposing I wanted to change the texture so that it looked like a Jordan F1 car (for example), then with a good art package and a lot of patience I could change the bitap that comes with the model and that's what I get - a model of an F1 car that looks like a Jordan.
Now suppose that I wanted another car that looked like a Ferrari F1 car I could do exactly the same as above and it would work but I would lose my Jordan.
If I wanted to keep them both and use them in the same program (and I do) then I thought I could change the filenames of the model and the bitmap. It sounds like it should work but it doesn't. ragardless of the filename of the model it always loads the original bitmap for texturing.
So onto my question (at last!) How do I get a model to look at a different bitmap for texturing?
