Firefly always had a problem with scale in poser. There's a thread by ronstuff explaining how to parent all your scene to a box and scaling the box 1000%. This fixed a LOT of issues for raytrace artifacting. Scaling the box will not scale bumpmaps so, you'll have to do it manually (0.01 becomes 0.10) at 1000%. I'm of course, guessing here. P6 could have new probs.
