I have this problem with a discoloration of textures in some cases. It is only visible when bumpmaps are turned on.

I've been using Poser 4 Pro for a year now, but I have only noticed this problem recently. I can't say for sure, it could possibly be due to the fact that I'm using higher resolution bit- and bumpmaps than I've usually done before. But occasionally I've used hires textures and bumps before and not had this problem.

Does anyone know of there's a way around this problem, other than turning off bumpmaps? What's causing it?
