Here is the problem:
the bottom of my cat is connected to the whiskers part, and I don’t know how to change that. I tried with the normalise things and it didn’t work.
Anyone has any tips? thanks
You might have a situation where two vertices just happen to be at mirrored locations (butt and whiskers) even though that’s not an intended mirror axis, and you have mirrored painting on. Make sure that all symmetry axes are disabled in sidebar/tool/symmetry then try again.
Otherwise, I’d probably have to see a file to figure it out.
It was that! I had the Y mirror activated in the sidebar ( for possible future noobs like me: in the weight paint mode, pressing N ). I was looking everywhere before, can’t remember when I activated it. Thank you!
