I am rigging an elf and am satisfied with everything……. except the arm bone. Every time I move it, the ear move. I tried weight painting so that only the head bone can control the ears, but that didn’t work. I even checked the vertex groups, but nothing seems wrong. What should I do?
Have you checked the lower arm bone and the hand as well?
Also, it might just be a very small blub (seeing that it does not wiggle much). → vertex paint it again with weight 0, strength 1 and perhaps a constant fall off. Tip: if you can keep the arm pose duringpainting to see when is snaps back.
Is the head a separate object? probably not, but if, you can remove vertex groups which should not influence the part of the figure.
The head is a separate object by the way.
Enter edit mode, select all, make any vertex active (by selecting it), open sidebar, go to item tab, vertex weights panel, set the head bone influence to 1 and click copy
I already fixed the issue before you replied. The problem was that the hand and thumb bone were controlling the ears, so I edited the weight and that fixed the problem.
