I am using Blender 2.8
On my last work I encountered trouble with mirroring my weight paints. My bones are named correctly with R and L prefixes. It may look like everything work correctly, I press Mirror, under weights panel, and my paints are transferred to another side. The only problem is I want them to be copied to another side, not transferred, because my model is symmetrical, and I want same weights on both sides.
Thank you in advance ;).
