Glass dispersion with participating media scattering with bidirectional path tracing, Metropolis sampler and network rendering (aka the BFG9000 ):

We have an attic full of crappy pcs that we sometimes use for small LAN parties (age of empires II etc.).
Can't wait to combine their "massive" computing power with network rendering

wow the phoenix is back !

I'm bit lost sometimes between dispersion and spectral rendering. Is spectral enable in your render ? Do you think switch option between RGB & Spectral will be exposed in Alpha 2 ?

Yes and yes.

how many time on a regular i7/R7 (i7 6700 / R7 1800x) to reach the same level of noise for the same resolution ?

It was BIDIRCPU+METROPOLIS so was running on my i7 3930k (an old six cores) and i7 860 (an even older 4 cores). They (combined) run about at the same speed of a AMD 1800X.

And what was the render time?

I don't remember exactly but something in the range of 20 minutes, it is quite fast to render. You can try to render the scene if you want, it is scenes/cornell/cornell-vol-caustic.cfg (https://github.com/LuxCoreRender/LuxCor ... es/cornell).
