I've recently implemented this, with good results (particularly from the diffuse multiple scattering) but I'm stuck on how to numerically integrate the diffusion in order to calculate the Rd->alpha_prime table for artist-friendly parameterization. Has anyone else implemented this? Or has read the pa...
My suggestion is to clamp the sample contribution in image space to some maximum value. Implementation is trivial and doesn't require any path and material roughness tracking. The downside of this method, however, is that you will end up clamping contributions that are not noisy, e.g. directly visi...
