I was discussing the shoulders recently. There's that kink on the top of the shoulder, and different DAZ figures need different tweaks to collar and shoulder positions to minimise it. There's also the problem on the inside to the knee and elbow. Posette has it really bad, but it's still there with V3. It looks as though there's a limit to how much the mesh can bend from the zero position. At least V3 doesn't have that weird bump emerging that Posette has.
