It's broken for me too. Every "Tilt & Pressure" setting just detects tilt apart from size, that works correctly. In regards to tilt and pressure, can an "inverted tilt & pressure" be added? With inverted I mean inverted tilt but normal pressure, as you can invert them both by editing the curve. Could we also get random angle dynamic?
It's not brush specific in my case, I just tested a couple custom brushes I already had
