So I've been getting this funny little bug where when I'm in the middle of weight painting my mesh does this: No apparent reason, I haven't figured out what causes it and the only bright side is that I figured out how to fix it without throwing away all of my previous weight painting. But it's a pain in the butt.…
You could be running into an issue with the normalize weights option. Last time I painted weights I remember the "Interactive" weight painting was trying to normalize weights to joints that I didn't want any influence on. I think I changed the option to "Post" and it worked better. Also, when I begin painting I always…
Thanks, I'll give it a go if this issue arises again. So far it's been good with my other meshes and I haven't had a need to weight paint the face again.
Leave it at "interactive". Im sure its the weights cant be applied because of too many locked weights. One can work actually very clever with weightlocking, but its also a bit shaky. Sometimes the normalisation doesnt work. I would try to unlock the weights, and the normalisation should fix the problem, as you described.…
It's odd that it would happen though, I just opened this on my schools computers and it seems to be working fine now. Maybe restarting may be the cure. Hopefully it doesn't happen that often (It has happened on my schools computers as well and on different meshes). I still can't figure out why it happens though, It happens…
