That's nice to hear. I want V6! Is it possible to implement some kind of adaptive raycount, i.e. before starting the real tracing, the Raytracer object looks around a bit for close objects or close surface curvatures and determines raycount from there. For this first step, no materials would have to be evaluated, just geometry. Basically, what I mean is: use high raycount/low blur where it's needed near details and corners, low raycount/high blur in the middle of large areas. The Blur effect would have to be adaptive too - difficult...
Some sort of adaptive sampling would be nice, but if I remember correctly, the RayTracer object already does this with higher RayCounts. This doesn't affect the blur kernel size though. What you're describing is pretty close to how photon mapping works, which would be nice to have in RS.
