omg.. just opened the material list for that peterbilt... nearly every material line has a raytracing map meant for rendering in 3ds.  think i'm going to re-export it as an obj with no mtl file and set the maps manually...  guy who made it was pretty in-depth.. fortunately he named everything with nice descriptive names..  all just practice for me.. not this quarter(just started) but next quarter in school I start my solidworks classes(CAD and architecture major).  I've seen the rendering that solidworks and 3DS does and it doesn't hold a candle to the D|S - Reality - Lux flow and lux just renders things so beautifully.. it's going to be my secret weapon to give me a visual foot up on the competition in school.  can't wait to start learning how to make stuff like this peterbilt.
