Not a script but still usefull
For many max versions i have been using Scene Explorer: http://sourceforge.net/projects/se-max/
It's a pluging to view and edit your scene hiarachy and manage your layers. In my oppinion it is vastly superior to anything that ever shiped with Max.
My problem is that it's not compatible with Max 2009.
I was hoping that someone with the ability could recompile it for Max 2009.
Since it's open source there should not be any big deal to it.
Thanks for any effort towards this.
