A smudge tool to help build color in shapes that don't have defined edges or require color gradients
This brush is mainly to use to help gradients have more textures or to have a cloudy effect when rendering rough shapes like shrubbery and clouds.
Examples below is how I use this brush, mainly to help build color transitions and to help block out objects that aren't going to be well defined or will need building later. You can play around with the amount of paint, paint density, and color stretch to give more variety to the texture. I don't often use for features, but its nice to have!
Forgive my use of my cursed PNGTuber model, it was the most recent example of me using this brush
