Almost forgot, there's two bump map channels in P5, a gradient bump map, and a standard bump map. The gradient bump map is for the older P4 style bump maps. The standard bump map is for P4 Pro and beyond bump maps. In p5, regardless of the type, bump maps default to the gradient bump map channel. You'll have to manualy switch the channels over if you want the bump maps to render correctly. While I'm at it, is there a script out there that will do this? ~DM
