So I'm pretty happy with the textures I have going on here. I started the rig a while ago and have been posting about the progress on CG Society. You can check that out here;http://forums.cgsociety.org/showthread.php?p=7090003#post7090003
I ran into an issue with the rig that no one over at CG Society has responded to yet, maybe someone here can help.
So the problem I'm having is with the spring object within the dynamics objects roll out. I have these springs set up for the shocks and I wanted them to stretch when the body of the cart was pulled away from the wheels, I had a handful of shots in mind where this would happen. So I have a spring object, and the top and bottom are bound to their own point helper so that I can manipulate the spring. I found that I had to position constrain the top point helpers to the center of gravity controller and the bottom point helpers to the master for the wheels. With this set up I can lift the body of the cart up and down and the springs works perfectly, but when I rotate the body, the springs don't move with it. It seems that whatever you bind those ends of the spring to, only reacts with a change in position, not in rotation. So I'm kind of stumped. Basically I'm trying to think of a way to keep the top end of the the springs to stay glued to bottom of the cart, so that I can rotate and translate the body where ever I wanted and still have those springs work properly.
