I tried searching for an answer to this on a few different sites but I wasn't able to find anything. It's easiest if I explain in a video:

Basically I want to change the size of my brush by rotating my pen, but Krita seems to count drawing at a different angle as rotating the pen, as opposed to just twisting the pen. I tried using the tilt angle parameter to offset this but it didn't work. Is there a way to get the brush to behave how I want?
