That's neat, _dodger. I'll have to try that. As far as I know, Pro Pack handles bump mapping in the same way as P4. The BUM conversion is simply done on-the-fly, rather than saved to the hard drive. And it'll still use BUM maps if they are provided. In Poser 5, you can apply a "texture mask" to the Ambient channel, so that only specific parts of the material glow.
