Well, this is impressive.
I am not sure if this is exactly possible, but would you be able to make it so you can change textures?
Well, not change exactly, but make it so you can change some random room effects like Animated Textures and/or Room Effects (Jabu Jabus moving walls)
I guess you could do it in a Hex Editor if you know what your doing.
Anyway, this is really impressive. Hopefully itll be the next UoT, I cant wait til its out to try it myself.
