Hold on, I gotta take this opportunity at 3 AM to gush about how much I adore oC’s watercolor brush, because it is unlike any other tool I’ve encountered in any other program.
The big square with the circle in the middle is the brush preview, and just under that is minimum and maximum size for pen pressure. As you can see, you can only select the maximum size for watercolor.
To the right of it, that box with the crosshair? That changes how hard or how soft you have to press to get to the maximum size. It’s really helpful if you want a big brush you don’t have to push hard on (but still has small tails!), or if you want a small brush that can still go big when you need it to.
Those three rectangles in a row at the top? They control what your pen pressure is affecting. The first is size, the second is opacity, and the third is… well, as far as I can tell the third just makes the edges of the brush all gradient-fuzzy-like.
But finally, what I think really makes this tool unique, besides its blending ability, are the RGB bars. As you use the brush with your base color, it will actually blend in a bit of the colors you choose too!! I actually really like the color variation you can get out of it. It makes things look a lot less computerized, to me at least.
and that is why I love oC 1.1 to death even if it’s a pain only being able to work with multiply, addition, and subtraction layers
(the networking parties are worth it)
