Hi Peate let me go through your message one by one.
”very tight for specifically this area” Does that mean setting up a tighter zTet?
I'm not sure what a tighter zTet means. I was referring to using surface tension to encourage the tissue to web across the leg and the torso.
I've added a new material layer between the leg muscles and the torso.The interior and exterior models of this area are whitewashed and the rest are blackened and the pressure is set to 0.
For this type of work I'd recommend painting the entire fat tissue to black and then painting white in selective areas only on the inner surface.
When the leg is lifted, the model on the other side of the rib is jacked up.
I'm not quite sure what jacked up means but it definitely sounds like parts of the fat are being affected that typically wouldn't be in a real creature.
When the fat is in this position, it is easy to have the problem of interlacing and pulling. How can this be avoided? In your description I see that you've added some material stuff.. Did you make the changes to your model that I suggested?
