or if you're really really lazy you could make a pose file that loads a buttload of textures for materials that aren't really in the scene (or stick 'em on a simple prop like an invisible plane -- erm, square that is, not the wonder woman variety)and afterards you can just select the already-loaded maps from the drop-down menu. Just save a pose or prop and open in a text editor, then make a material block for each three maps you want to preload. Why each three? because you can comandeer the texture, reflection, and trans for each material block you use. You can't steal the bumpmap except to use for a bumpmap because the pre-loaded bumpmap mwenu isn't shared, at least in P4
