When sculpting, my brush changes from Add to Subtract and viceversa When sculpting, my brush changes from Add to subtract and viceversa if i sculpt in some places of my mesh. How like that?



As it seen in the image, it switches or changes to add or subtract in some places, so everytime i have to press ctrl and stop pressing it because this thing. In some places flattens, in others just add, and it's absolutely annoying, can't sculpt in peace.

Maybe i pressed some "autocontrol-switch option" somewhere, or maybe not.

What's happening?
If you try to enter Sculpt Mode with your model, you can see the warning message Object has non-uniform scale, sculpting may be inpredictable .




First, select the object in Object Mode and then Apply the Scale by Ctrl+A > Scale.
Then go into Edit Mode, select all by A and Make Normals Consistent by pressing Ctrl+N.
If normals are now inverted, invert them back by W > Flip Normals.


Then your sculpting tool should work equally on the whole model.
