I’ve been testing one of my recent characters and have linked that character into a scene file. While working on it I realized I needed a new bone and bone constraint. I went back to my original file, added the new bone, made the new bone constraint and modified the rigify script so I had a custom slider.
When re-opened the scene file, the new bone and modified scripted updated just fine, but the bone constraint does not show up.
Any thoughts as to why this did not work?
