Thank you in advance to anyone who assists me with this, I have been stuck on this problem for two days now. I have the same bone armature along with identical hand meshes, one just mirrored. When I automatically weight the objects the left hand works perfectly while the right hand is attached to multiple fingers.
I tried searching for ways to fix this without manually weighing every finger as its very tedious, unfortunately I couldn't find a post with a way to fix this.
Left Hand that is working correctly: [ https://gyazo.com/4b0aa45edfefcf9a3d083ab616887887 ]
Right Hand, which is copy, pasted and mirrored to the correct direction: [ https://gyazo.com/ec044e1b62b559bcd2f65a68759bc04a ]
Here are the weights. Once again, an exact copy and paste. Yet automatic weight caught different sections of the hand.
