Why vertices are changing their position during Weight Paint Mode? I am new to Blender. I am making a MineCraft character.
In the Weight Paint Mode, When i am assigning weight to vertices they are changing their positions. Like, a small change in global z axis or along x axis.How can i solve this problem.[![enter image description here][1]][1]
Thankyou.

Via weight painting, you increase or decrease influence of the bones on vertices. That's why they change position. If f.ex. some bone influences a vertice with strength of 0 nothing happens, but when you give this vertice weight of 1 it starts to be influenced by this bone with strength of 1 and it's moving closer to it. This is normal and expected behaviour. Although your example looks weird.Could you provide the .blend?
