Already seen it before but decide to look closely at it today and it is really really mind blowing. Also notice that the more probes you have better will be the quality and rendering are always under 1scs. so we can match Brute Path tracing in just minute easily or with Beefy CpU or Opencl version on GPU in just few sec.Could it be... the next step for light caching?
Normally upcoming ILCS is more robuste than Vray light cache (it is suposed to be unbiased) so i expect less limitation.But I wonder if it also can help with rough glossy reflections similar to vray's lightcache.

Three sampling strategies fused by MIS: central pixel BRDF sampling, neighbor-stealing BRDF sampling, light sampling. Here in glorious 15fps on my GeForce 940M It's all specular btw, even the diffuse-looking walls
im pretty sure this idea the kelemen mlt paper. a variation of this is already implemented at the heart of luxcore and is available as the metropolis sampleroldladyfear wrote: ↑Sun Nov 11, 2018 4:26 am"A Simple and Robust Mutation Strategy for the Metropolis

looks like it could be a simple way to increase the performance with little overhead.
