Use your own textures for this brush! This brush is will also not cross the referance layer which make it easy to use!
This is a texture brush in which you can use any of your own textures.
To change the texture or add a texture to the brush, go to [tool property] > [texture], then a box will pop up titled [select paper texture material]. Click on the texture you want and press [ok].
This brush has a [do not cross line of reference layer] feature. This allows you to draw within a certain area without having to erase. With the feature turned off, the brush will cross the lines. (You need to have your lineart swiched to a reference layer for this to work!)
[texture density] allows the background layer to show through. The more you turn the [texture density] down, the less background will show through.
