Was trying to weight paint an object and I didn’t understand why it moved the way it did, until I found out about normalize. Once I normalized all groups the weird moving area was all-red, which made sense. BUT. Now I dug into normalization to figure out how it works. And there are some things I don’t understand.
I have an object with 2 bones. All vertices have weight 1.0 on both bones. If I move a bone it looks right, it’s affected equally by both bones, as expected.
Now I go to weight paint and under Weight Tools select Normalize All. I go back to edit mode and look under the N-panel. My randomly selected vertex will have weight 1.0 on one bone, and 0.0 on the other bone. I had expected 0.5 on both bones, since the normalize description says they will keep their relative weight. This goes for most vertices, though a few have something like 0.994/0.006 or even 1.0/0.0000006. With this behaviour I don’t understand how to use normalize all, since now the object will react completely different to bone-adjustments. Can someone explain this behaviour?
Also. If I choose normalize (not normalize all) in Weight Paint, nothing happens to the group. If I instead use the Normalize in Edit mode under Vertex Weights, then I get the expected 0.5 weight on both vertices.
I posted a version of the same question here:
There’s a gif that shows what I’m doing as well, couldn’t add the gif to this post.
