The brush itself belongs to ka05's splatter brushes on Deviant Art. [link]
I have made it smaller and this is to be used for smudge settings...
Smudge settings are available exclusively to PlanetRenders.net members only + a select few gruntsrus.com and other web site members.
Comes with two brushes. 77 and 55 size.
Strength: Varies. I use 40, 60, and 90. use whichever one u think is best.
Actual smudge settings are at planetrenders.net forums. In like a month they will be free.
In case you don't know how to download 'em juts click download and go to Adobe>Photoshop CS_>Presets>Brushes. Save there and then when you load photoshop click the "brush" tool and then click the arrow 'load brush preset' and then append.
