Hey,
I think It would be nice if there was an option to offset or rotate the lowerarm/hands in/outwards, I’ve noticed a lot of models I’m trying to port have this issue where the hands get inside each other or even are inverted when doing the Pistol pose.
Note that the shoulder options used to move the whole arm which usually fixed this issue at the cost of the shoulders looking a bit wider, but now the shoulder offsets don’t affect the hand position at all unless it’s taken to the extreme.
Here’s some pictures so you see what I mean.
I’m no expert on blender or anything, but I didn’t have this issue as much with the previous rig lol
