hi gster123

thanks for replay. i know with IPR render is easy and quick, but i ,m using some gnomon maya dvd training. In the dvd lecture he use normal modeling view. and he does not need everytime press IPR render, so should be somewhere that need to be turn off or on to see the bumpmap,
i try contact the lecture of dvd , but it is hard, he use all the time for explain the dvd's, but he did not explain how to see the bumpmap. so it is for me question, it is in somewhere, but i don,t know. it is gnomon car modeling dvd. any help welkom
