Topic: version 4 MAXScript Language Improvements/Language Improvements
A forceUpdate function added to MAXScript.
Right now when the user changes the topology Unwrap resets the mapping. If the forceUpdate is set to true then the mapping will not be reset, but you can't edit/see any mapping that makes sense. This flag is for advance users that want to lock a mapping and then set the topology back down for maximized viewport speed.
forceUpdate(BOOL update)
