Is there a way to scale the Brush size/settings with how far I zoom out?

Say I want to draw something in high-resolution, the only way I know to do that is to zoom all the way out and/or make a frame with the resolution I want. The problem is, the brush size doesn’t scale along with it. Is there a way to scale it exactly with the size of the image, or would I just have to adjust the settings until I get it to the size I need?

There is a custom input in the brush settings that you can map to the Zoom Level. Then you can use that “custom” input in the brush radius to scale it negatively with the zoom level. It’s not totally precise since it just adds to the current base radius but it might do what you want.

I prefer to just scale the current brush using the keyboard shortcuts (see Preferences > Keys > Increase/Decrease Brush Size)
