I've been looking at some tutorials, and some of them call for smudging. Most of these tutorials show the menu that they used for brushing, and it has options such as "Scattering" and "Smoothing" ticked. Whenever I go to my brush menu, I'm not able to select these. Is there a way to unlock them? Please help.
