Version 2.1 is out. Fixes some missing features in Max 2010 & 2011 (Display Walkable wasn't working in them) and suppresses errors for features not supported in Max 2009 and older. Also ads a placement helper.
When I loaded this file it was supposed to fix an error in Max 2009 and older... but in reality I loaded it with the wrong version number to check against. I've updated the files in the latests download... but didn't bother to make any version number changes.
