Over the years I have written a bunch of scripts for collapsing geometry, especially since I started working with CAD files more often. I finally had some time to wrap them all up into one interface for easy use.
The collapse tool is very simple to use, you can collapse the selected objects only, by material, layers or an individual layer. Most importantly it has been optimised for collapsing large object counts. A progress bar is displayed so you know Max is still doing something, unlike the standard collapse tool were you often wonder if Max is still working or it has crashed. You can also hit escape to stop as well.
By default it will do a scene hold before the collapsing starts. Max’s undo function is also turned off to increase performance and memory usage. Both of these options can be turned off or on. I am currently adding the option to create a multi sub mat for the collapsed geometry. It is mostly working at the moment but needs further refinement and optimisation before it is released.
As usual if you have suggestions or run into any trouble please post a comment below.
