hi
I have a little problem.I was generating the controller on metahuman when I removed the rig group and found that the model was slightly deformed
Did you bake your joints first?
No, I just deleted the rig group
That’s your answer. You severed all the connections, so yes it breaks things. Bake the joints first, and it won’t happen. Then you can safely delete the rig controllers.
Unless you mean the problem is that your rig is building into a non-neutral pose. That might be a different issue.
