(It is possible to add your own textures to Vue by using .bmp files. But how can I create the .mat files myself? How do I convert textures into that format?) Yes it is. Open the material editor check coloring mode. Click load then find the bmp picture you want as your texture. Now go to your bump tab. Right click the bump picture icon and select edit function. A new window will open check mapped values. The bump icon will go black in the lower right corner you will see another square black icon double click that and then find the same bmp picture for you bump mat. Click ok now you have a bmp picture texture and a bmp bump mat that match. :O) CLR format I believe is an HP printing format and you may be able to convert that in Photo Shop. Best of luck.
