Okay, so I got a little improvement by decreasing the “spine bend multiplier” to -0.3. But it looks like “spine 01 and 02” are being influenced, but “spine 03” isn’t being influenced at all.
As for the clavicles, I don’t have a problem with them when the arms go up and down *vertically (it still could be better), but when I move my arms left and right *horizontally, the clavicles aren’t being influenced at all. Or if they are being influenced, it’s probably extremely subtle
