When working with Victoria 4(not sure if this is the same with 5-7) I've run into an anatomical problem with the depth of her shoulders front-to-back that's somewhat annoying, particularly with some poses. It's not really anatomically correct, especially for a more slim or thin figure. Is there a way to adjust or morph the depth of her shoulders so they are less thick front(chest & neck area) to back? Somewhere in the parameters, perhaps after clicking Show Hidden Settings in that tiny box, there is a setting for Shoulder Blade Depth, and I tried that, but that didn't do what I was wanting.

I dont think there is a morph for that. If you have another modeling program you can try to do it yourself.
