I in the earlier post in your blog, I remember, that the Brigade showing some pretty good implementation of MLT and pathtracing, clearing caustics and tough scenarios with ease. I remember, that there was an interior, which was lit only by an opened door and the brigade implementation of MLT was been able to lit and clear the image really fast, comparing to the pathtracing. There was another scene with a ring, that showed caustics resolving pretty fast. I was wondering, is there an option to implement and add this kernel, that Brigade was using, into Octane, to speed up the rendering, as the current PMC, pathtracing or even Diffuse render in directlight mode are not efficient , slow to render. And is there a possibility to finally add a switches, so we can disable caustics for indirect or direct light sources, together with turn on/off lights sources, bumps, etc., known as diagnostic mode? This seems doing a great job in terms of speed up, in other unbiased render engines, GPU and CPU based, cutting the unpleasant fireflies, speeding the render.
PS: To add to the list with the optimizations, that can be made real time, trough all the materials, with those switches, that will give us a lot of speed up:
