I didn't think I was asking for a benchmark. What I was interested in was the manner in which Max will save the modifiers. Some graphic programs with "undo's" will save a copy of each of several versions of a file and therefore the file will quickly grow very large. I wanted to know if each modification is saved as a discrete object (like a morph target) or is just the modification _data_ saved? Alec Jason
