Yep thought that, but when I have made the object editable and I apply dynamics to it, the model implodes and explodes at the same time. I can make it work perfect for a simple object like a square or sphere but models like a cylinder do this implode/explode thing. Its as though the model isnt classed as solid and each surface hits the other and goes wrong.
Im probaly doing something worng with this side of things, I think I might be able to do this if I could sort the model side of things.
Thanks in advance.
