A P4 bum map is weird colors and has embossed channels. Poser Pro Pack uses a standard greyscale bump but can also use a P4 embossed style .bum (which is actually a .bmp). P5 can use a .bum, but it has to be plugged into the gradient bump channel. What I used to do was provide information in the Readme that told P4 users which files to convert to .bum so the MAT poses would work properly. Now I pre-convert (with the weird embossed channels), save as a .jpg, and make the P4 MAT poses point to the P4-style bump (yes, P4 can read a .jpg for bump, but it has to be pre-converted and it has to be applied by a MAT pose and not manually). bonni
