Hey all..... I'm new to mental ray and am looking for some good tutorials on mental Ray's shaders. I've also been told that if you use the native maya shaders in mental ray it takes longer to render....anyone know if that's true? -D

depends on what you do. Dgs for sure is more expensive for the raytrace simple blur than mayas native ones. Thye are in mr code youknow.
