So when you have a bump map, how do you get it to show on the model. Do you put the dot in column A next to the bump height and then use the slider to control how much impact it has? And do you have to convert to gray scale? I tried loading the same color map I was using here, figuring it would convert it to gray scale. But I'm not getting much of an effect when I do that. Or does the bump height only work with the procedural bumps? Thanks. Kevin
