I have a model and rig that I'm trying to mirror to the other side. When I try to perform the operation it works totally fine on last weeks file. But when I do it on my most recent file, it doesn't seem to work. Even though I'm doing the exact same sequence. I've included a video displaying the issue and here are google drive links to the files in question.
If anyone has any idea how to transfer the weight paints properly from one side to the other in my recent file, I'm open to all ideas. Thank you very much for your time!
