This is caused by using Gen4 poses on Genesis. The models have different bone structures and so the poses are not fully compatible.
The fix previously posted will help to correct the problem.
I haven’t yet figured out how to save pose presets in DS4, but if you do you could use the pre-genesis pose, use the fix and then save as preset for use later.
I have also seen this occur while using Genesis poses…that is what my fix above is for .
It seems to happen when the rigging is out of alignment, so far I’ve only seen it where I have used extreme scaling,I suppose that is why they have allowed the ability to create rigging for different shapes.
I am posting some pics of Genesis prior to using my fix and the same figure immedieately after applying my fix.
One note, I did make an error in my description of the selection after edit it should read adjust rigging to shape not align to body shape as I had previously written.
