I have tried by playing with settings (pressure and thinner in particular) to get a dry brush look where you can see the individual bristles of the brush and can use it to scumble one color over another. I have not had success.

It can be done in Photoshop by using a brush made from a sample of some random spots to simulate the bristle spread of a dry brush. Is this effect of opaque paint scumbled dry over an other color obtainable with ArtRage Studio?

Here is a sample of what I mean:



Thank you.
