How to zero velue a red area of weightmap?

When it's 100% red I have to use the S brush. Because if use the P brush. the value won't change at all. Selecting area and setting value to 0% also doesn't work.

But S brush is like just moving/distributing around value from one bone to another.
If I fixed a weight map in one bone, it change the value of other bone, back and forth.

How to solve this?

Weights shall usually add up to 100. So in order to get it to 0 for one bone the weights must be distributed to other bones.

But I want certain area to have no weight... for any bone....

How do you want the area to behave when posing?

You could create a child bone and assign all weights to that.

James

The area have to stay the same, when posing.
I'll use morph to accomodate body pose situation. and use Dforce to follow the body.

Hemm... wait maybe I shouldn't do that...

If you did that then the area would be left behind when the figure was moved. If you want it to stay unchanged by posing then assign it to the hip with 100% weight - but be aware of what will happen at the boundaries. Orif this is to be a 100% dForce simulatd item don't rig it at all, as long as you don't mind having to start from a zero pose (or whatever pose the base shape fits).

I see.

I suppose that you're manipulating the weight on a wearable other than a Base figure as we rarely touch the latter... Technically you can carefully select the polygons or vertices relate to the 'red area' of the weight (100%) then use Attenuate or Fill Selected to modify the weight then repaint or smooth it.
To avoid the influence to other bones' weight when you manipulate the weight on a Bone, you can Lock Selected Bone(s) Weight first by selecting other Bone(s).. for instance, if you modify the weight of a Parent bone, you shoud select all of its children bones for Locking.
