Size/Opacity

[snowhawk]

Hey, I am on version 20.10.30. I need to know how to adjust pen pressure for size/opacity at the same time, like Photoshop. How do I adjust the new brush dynamic? I don't see any way to edit brushes (new ones) .. I can change thing in the mapping matrix for a new brush, but it didnt change anything, even when I adjusted the curve.

So basically, how do you adjust pen pressure for size/opacity at the same time.

Thanks.
