I've noticed a few Vue artists who get an almost impressionistic "brush stroked texture" for lack of a better word, in their renders. Guitta's *A L'OREE DU BOIS* comes to mind right away. My question is how to get this effect of brush strokes in a render? A bump map for the whole canvas? Or is it post work? i.e. Photoshop's Art History brush or something similar.
