I'm weight painting my character and some of the vertices on the finger are not moving with the others despite the fact that it is included in painted area.

Here's the example of moving the finger's bone and it's top view with vertices selected. enter image description here

Maybe you've got some ideas of fixing that.

  • $\begingroup$ The bone's name is index1.L but actually bone named spine2 gives the same problem and I cannot understand why. As for spine2 when rotate it along the X axis so the character leans left and right several vertices on the neck are staying on the place. $\endgroup$

If I enable the modifier's On Cage option, select the vertex, open the N panel and take a look at the Vertex Weights, I can see that this vertex is also part of the group called Spine2. Just remove it from this group (press the X button):

Parenting With Automatic Weights won't always work fine, you often need to give it correction in Weight Paint mode. Select the armature, shift select the object, switch it to Weight Paint mode, select a bone with Ctrl left click. In the brush settings, don't forget to disable Front Faces OnlY if you want to paint through:

  • $\begingroup$ Thank you very much! Finger issue is actually solved. What do you think is the reason for these artifacts? drive.google.com/file/d/1ZzYPFm-VZpf2a7vrmqRMXuBavlgehHSZ/… $\endgroup$

  • $\begingroup$ same thing, it's a bad parentage issue, but it's hard to tell how it happened, as I said if it's caused by the Spine2 bone bad parenting, then try to reparent for this bone only for the moment? $\endgroup$

  • $\begingroup$ Spine2 has spine1 as a parent. Which other bone should I assign it as a parent? I used empty groups for all the bones not automatic $\endgroup$

  • $\begingroup$ reparenting With Automatic Weights doesn't seem to fix the issue, you should try to correct that in Weight Paint mode. In the brush settings, disable Front Faces Only $\endgroup$

  • $\begingroup$ That's exactly how I'm trying to fix this issue with Weight paint mode but I don't see any vertices not included in any of the bones. Why can this happen? $\endgroup$
