Any brush above the line works fine. Any brush below will move the object instead of doing their work.
Any time I choose the advanced brush(below the line), drag on the object and the whole object will be moved just like using the ‘move’ brush.
Once I released the mouse(drag end), the brush will change to a basic brush I used before(clay,strip).
I have tried installed a few versions of blender 2.9x. Is there any settings I don’t know? I think I’m sort of intermediate blender user, I never see this occurs on other people I know.
