I like to do do a very simple, i.e. loose/rough, watercolour or colour pencil effect in a viewport. My drawing is all 2D, just a group of classed polygons that I'm building my plant list from.
I've followed Pat's advice from here -
But the effect is underwhelming, just simple blocks with loose edges but no colour blending or splotchiness. I've been doing my nice images in Rebelle (which is now close to the real thing), but some times I just want quick and dirty like now.
Has anyone developed a workflow to do this? Also, how do I avoid a black background?
