I would like to know how to mirror skin weight from left to right. enter image description here I have prepared symmetrical bones and did paint weight only left side,

.

And run the script called "Mirror Vertex Location & Weight" in edit mode as selecting all the left vertices. Then I got syntax error in picture below... enter image description here

I would like to get advice about how you do mirroring all the weight at once..

like "mirror skin weight" in maya. enter image description here

thank you

  • $\begingroup$ You should try the mirror modifier. : blender.stackexchange.com/a/9392/86891 Tell me if you can't get it to work, I'll post an updated answer $\endgroup$

  • $\begingroup$ thank you , I read the page. I thought it is useful if i use a couple of bones. when I have arm1 arm2 arm3...etc, its bit complicated. I found this page,, blenderartists.org/t/copy-and-mirror-weight-vertex/556790/11 the script written by mathiasA in Dec 2012(which is at middle part of the long page.) It worked to mirror all vertex group at once. $\endgroup$

  • $\begingroup$ Oh Okay you only want to mirror some vertex groups, not all. You can either add the errors in your question so I can try to troubelshoot it or add the code so I can see by myself because the python API has changed in Blender since 2012 $\endgroup$
