I have used texture paint to paint a rust texture on my mesh. When i discover paint at undesired places i try to set the blend mode of the brush to subtract. The issue is that this doesnt only remove the painted texture, but also leaves marks where there was no painting done.
So my question is how to remove texture that has been painted on with texture paint mode,
I know i can ctrl-z, but this is after the file have been saved and closed so there is no undo steps available.
The selected texture is the paint texture. You always can edit it or simply delete it and create a new one. To do this, jump back into texture paint mode.
