True displacement instead of just bump-mapping. Area rendering that affected part of the original image (like "plop rendering" in Bryce). Getting the function room to be able to automatically change it's node's input/output parameters to match those of what you want to plug the function into (like Poser's materials room does). A way to push the preview updates to the top of the priority list, so I can see more quickly the effect of the latest change I've made. (Plus many more I can't remember at present.) Some of the above may already be available, if they are I'd add "a better "how to do" section in the manual":-)) True displacement (I know I've already said that, but it's my one, real, most important wish-list item) Cheers, Diolma
