//I've extended the mesh converter so it only reads certain mesh subsets.
Can you share this?

Breakable objects are almost ready in Newton's code, that is written in c++.. somebody just may convert it from c++ to lite-c and work is done
i'm working on character controller and car controller, in addition i dont have enough time for that... maybe, after controllers i'll go to brekeable objects.
