Ok, well that's still useful. It would be ideal if there could be a script compiled that would take all the existing texture nodes that may be in the material room, remove them all, then apply the base white color. It's simple enough to just apply a previously saved white material to individual body parts on a figure via the material room, but it would be so much more efficient and time-saving to have a script that can do it all at once on every figure in the scene, including all props, etc. Even if it didn't have "undo", it would be the most functional solution for doing an ambient occlusion pass on a scene without having to manually go to every individual prop or body part and changing the material. Is that possible, Ockham?
