Zhann, Not sure I understand the situation but: If you use grouper and the poser bump map is in bum format you can convert bum maps to something usable from within grouper. If there is a seperate poser bump map give the bmp map it's own channel(2), and only use the bump height with channel 2. If there is a seperate poser trans map give the transparency map it's own channel(3) and only use the transparency with channel 3. just my uneducatable guesses, - TJ
