Vray 2.4 3dsMax 2014
We are doing a photo-real macro shot of a chocolate curl (vrayphyscam, domelight, area lights) with in-camera DOF. When no bump is applied to the shader, the render blazes. When I use any sort of bump, the render times more than double. I understand that there is much more surface subtleties that the DOF must consider, but wow the time just sky-rockets. Am I missing something? Is there a way to tell Vray not to spend so much time worrying about whether or not to "bokeh" a small crusty chocolate highlight and just blur it? Like a "bokeh" threshold? Like I said, when the surface is smooth, it doesn't need to sample so much and goes very fast. Is there some way to tell vray to blur it as if the surface is still smooth? Thanks -chad
