@agustrusher(View Post) The problem is, that we have no idea how they do it because there is neither a source code for OE-Cake and/or PhysiCafe available nor a detailed explanation or any documentation. Mostly because PhysiCafe was planned to be a commercial engine for this stuff. Now Prometech (the creator of both things) is doing other stuff like Particleworks, so it's pretty much abandoned.
