Here's a sample from the link ArtPearl......nothing to write home about really, but illustrative of the success of doing the 'postwork' for the distribution maps in the function editor instead of PS. I managed to blur out the hard lines of the cavity map by blending with a fractal and an ambient occlusion map. It got rid of any visible UV seams from the 3dCoat object. Also I used a 'template' of black mixed with white via the distribution and then just substituted a darker and lighter complex material.
