It will read MAT files. If it involves materials for P5, there is a difference in the way the two programs handle shaders, so they are not interchangeable. Although there are ways to simulate similar shader types...it's a matter of settings in most cases. Remember that for the best "quality" render, sliding all the way to the right is best. If you need a good, fast render, then sliding all the way to the left to "speed" is the one you want to try. Cris
