Not likely, cuz as I seen Pro-Render examples by Pumeco, he has no shadows in his renders, only true ambience "shadow" produced by setting sky dome ambience to black and turning true ambient ON in render settings. This combined with almost identical values for ambience and diffuse in material settings make his renders look the way they do. But, there is no true soft shadows there or real radiance, nothing can simulate infinite amount of light sources in Bryce. We can only do little "dirty" tricks, lol !
