Yes, MATS are a very good convenience. The first time I decided that was when I tried setting up the textures for the SAMS3D saloon. Man, that was some wonderful and complex model. I had such trouble figuring out the textures, and setting them up. Then I remembered there is a better way.. and a way to save others the hassle. So that was my first freebie: the MAT files for the saloon. It's a pain in the butt to setup textures for Mike, Vicky, et all. I much prefer MATS.
