Hey guys. I finaly upgraded me to 4.2 from 4.0 and have encountered a problem if anyone could please help....
I am currently creating a fat guy character, and throughout the modeling I am testing him with the biped rig (in 4.0). He will have a belly, so I have been using the belly option, which has been working fine.
However, the belly in any rigs I create in 4.2 are not dynamic, and they just stay put!
The rigs I made in 4.0 open up fine in 4.2 and work as normal.
Here are some screenies. The first is a biped rig created in 4.0, but open in 4.2. The second is a rig created in 4.2 and open in 4.2
In the 4.2 rig the belly has no secondary motion. It rigidly follows the hip area, whereas the 4.0 rig works as it should.


Any help guys please! I am the only XSI user at my college so our Maya dude cannie help!
Thanks alot guys
