OK here is a scenario…say I build ten objects piled on top of one another, like a stack of cubes for instance all twisted around and piled together like a mountain. Say I want them all to crumble and fall over top of one another and land in a perfectly streight line on the ground. I can get the key frames in from the start position to the finished position. My problem is the in between. When they fall over one another, some of them go through each other or intersect in the mesh. Now if these cubes were turned into bolders then that would look silly! So how do I make it so my cubes or bolders fall naturally? If a bolder hits another it should bounce off it and not go through it correct? If you have an answer or tutorial I will be more than happy to go through it and do the work.
