annoying deformation problems
 

Does n-e one know how to make an underlying model, for example a sphere, that can stop or prevent geometry going thropugh it. because even after painting weights for this rigg the stomach bends in instead of out when it bends foward.

How could i get the stomach to deform realistickly?

try doing it with the set driven key technique?

if you just want it to be by joint power alone, you'll need to really get particular with the weight painting. The position of the joint within the mesh would also be a factor.

To get it as realistic as possible, you could also make use of blend shapes to get the fine nuances of the contraction right.

thanks, ive worked out how to use skin weights proply.
