Does anybody have a file format description for the *.bum files that Poser creates for bump mapping? Got some of them that don't seem to work right and was also interested in going to/from bum, jpg, gif, etc without having to go through poser first. Thanks.

Larry Weinberg sent me the following: On Mac, the bum file is a mac PICT file. On win, I think it's just a bmp file if I'm not mistaken. The mac utility, Graphic Converter shareware) will read the bum file natively. FYI, I tested one *bum made on a PC and it is indeed a bmp file.

If you have MAC OS then check the Freestuff, Utilities. MartinC wrote a "SpeedBump" plug-in for Graphics Conveter to save as Poser bum images from within GraphicsConverter, much faster.

heyas; you can't convert anything to a bum. you can read a bum as a bmp or pict, but poser uses a special algorithm to determine the red/green values based on greyscale ramping velocity at any particular point. it's all very complicated and fascinating. :) similarly, there's no way to convert a bum back to a greyscale image. :/
