A small update is available on the beta branch. This just changes it so that surfaces using the leaves or groundplant vegetation shader will be skipped when computing a convex decomposition. This was implemented specifically to make it easier for Nenero to get his Tree Pack approved for sale in the Workshop Store. At this time, only the Windows build is affected.
I will be in Seattle tomorrow evening for Steam Dev Days, along with some other people from the Leadwerks community.
