I'm so very happy to hear C2 has this function! I've been hoping not to ever need to leave MC's old style of 3D apps. i.e. P5, V4, B5, C2 for thier much more complicated bretheren. This kind of caps things for me! I just browsed around through the Tutorials and Back Room areas, for physics Would you care to post a few screenshots, to help me get things going? I'm sure I'll be needing two different reactions from the force striking either the ground plane or another object, ore and stone. I ca'nt think of any other materials that may be in my collection. Has you seen presets for either anywhere?
