I can't weight paint on my lowpoly mesh. Brush just makes no influence on weights (only gradient alt + LMB making effect).
For example i want to remove weights for this bone (red selected) and this mesh (yellow selected).
Can someone suggest a solution? I am facing this problem every time i try to rig a lowpoly model =(
