Maya 2016.5 Paint weights becomes super strong at low values like 0.0001?

#1

I binded my character and now it´s time to correct weights…but, every time i paint in add mode at values of 0.0001… even do my mesh does not receive a lot of paint (no white) the mesh is super affected, it almost goes back to default position, for example, when the arm is flexed iff the bicep goes under the skin and i try to add weights to soften that area even at a value of 0.001 and opacy of 0.001 to the bicep makes a hudge movement insteed of a soft of by receiving such low values of weight…why is this happening, it feel like at low values like 0.001 or 0.0001 i am painting at 1…

Please help, basicaly i canot correct weights right now because of the crazy strenght of paint weights tool

That is most likely as

(1) You had locked joints affected when weight painting
or
(2) You have check the Max influence in the Skin Cluster Node option

Thanks, i fixed by unckecking maintain max influences… i didin´t knew this option has this effect.

You always want to turn that off, it causes lots of weird weight corruption. If I need to limit influences (like some game engines need) I use a helper to verify it, but maintain max influences is just broken.
