Which cleaner script do you use? I did some research quite a time ago and ended up with "the" cleaner script:http://www.scriptspot.com/3ds-max/scripts/cleanerWould also be interested in any reasonable alternative to compare.But the imho best method to "clean" a scene (if it´s only about objects) is still:- save out selected what you really need- merge into a new sceneGood Luck!
I use "3dwannab-CleanUp.mcr" also..Found it somewhere here http://www.scriptspot.com/forums/3ds-max/scripts-wanted/clean-bloated-max-fileHelps me alot!
I sometimes use this, although it's probably included in the cleaner script:t=trackviewnodes;n=t[#MaxMotionClipManager];deleteTrackViewController t n.controller;gc()
