What's going on with blender weight painting? I was painting the body bone by bone and doing great. Every finger moved the way I wanted to, the arms and legs were fine.

I try to fix up the shoulder bone and suddenly nothing works. I move a random SHOULDER bone and it suddenly has an effect on my legs.
Should I just use the auto weights?

go in edit mode and remove all weight from that bone's vertex group

I don't see the vertex group tab while I am in the edit mode of the armature?

Nor do I know how to remove all weight from the vertex group :(

There should be a checkbox for "normal weights" or something along those lines. Make sure it's checked.

Correction. Make sure "auto normalized is checked"

Not sure where to find it or what it does even. I ll just scrap entire thing at this point and make a new model.

I give up

Did that and nothing changes what does it even do?

How can a chest area bone even effect legs at all? None of this makes sense

Separate the mesh from the armature and rejoin them using automatic weights. Make sure auto normalize is checked and touch up your weight paints after

Everything apart from random eyebrow movement is fine now?

But why would the eyebrows move

Alright I fixed it by not setting automatic weight to the face. Thanks guys!

What's going on with blender weight painting?

Looks like you accidentally painted weights onto the leg whilst working one something else. Easily done.

Any bone can effect any area. Every bone (typically) also effects every single bone below it in the heirarchy.

>muh auto normalize

All auto-normalize does is make it so that that the sum total of all weights on a given vertex is 1. It's got nothing to do with what's going on here, which is a simple case of some weights assigned where they shouldn't be.

OP, check out pic related. You can change the weight painting color gradient so that 0 is transparent. Let 0.00000001 be where the color starts. This will make your life so much easier that it's franky insane that it isn't the default behavior.

Also, Weights > Clean

You can use it on a specific vertex group (that's a bone in your case), or all vertex groups, to remove all weights below a specified value.

If you did some painting Blender seems fond of overstepping the boundaries of your brush and consider every tiny pixel you touch as valid for strokes, same with texture paint, there is probably an option we have to manually check now because in 2.8x it didn't happen as often.
