Nancy: The textures are from commercial products.  The bump and displacement maps came with them. I think they were activated by default. Why, should I not have them?

Latex: I put part of the hair on the settings you posted, and it still isn't blonde. Now it isn't even blonde in the preview anymore.

I added my altered textures in the material room because I still haven't figured out how to save them to the material folder in my library. I saved them alongside the ones that they are based on (from the other application, not from within Poser) but they still don't exist in those folders when I open them from Poser. Does it make a difference in how the textures are applied if I apply them directly from the folder instead of importing them in the material room? What is the proper way to add new textures to the folder?
