a simple test for check my custom otl looks. it's a tool can add some detail after fractured the mesh. the debris emitter is also custom otl because Houdini's Debris shelf will not work correctly in my case.
the crack edge tool still WIP.
btw, I upload the debris emitter scene in here : get-igou.blogspot.tw/2013/10/rbd.html (another scene different with this video)
