cycles has this under review atm:
https://developer.blender.org/D5399

I will do it tomorrow (anyway, it is not only for bump mapping).

P.S. the problem is a bit more complex than in Cycles because it goes only from eye to light while we go in both directions.

Ah, fantastic. So this is going to be part of 2.2 release.

This is, hand down, the best stuff out of SIGGRAPH 2019: "Path Guiding in Production" (https://jo.dreggn.org/path-tracing-in-p ... index.html)

I'd love to see some pathguiding voodoo in luxcore even if it was cpu only. With todays cpu threadcounts we can afford some threads to do lighttracing and rest doing pathtracing + all the caches can boost performance a LOT.

I would really have no issue having to render something even on cpu with luxcore as env.visibility cache and photongi do have give a great performance boost.

The bigger problem for luxcore (for my purposes) remains lack of features (which I talked a lot about and they're all on github already)

But it is really exciting watching this renderer becoming very attractive for many purposes (why don't we have a in smilies?)

But i just always wonder why people give all that super complexe detailed paper for free. Considering they will be at the disposal of the competition.

True. Following since 2017
My path with tracing started in 2005 with Maxwell, Fry, Indigo and Lux (in constant flux). Which all took an awful lot of time to render clean VS Vray. But then with multi-core CPUs, GPUs & finally Corona, things just got quick and simple to handle. Reading about how and what each one does feels like watching sports. I'm simply fascinated by these 'intellectual gymnastics'.

I believe, it's in the human spirit of reaching the higher ground (officially, the academics).
With open competition we all grow, evolve and finally everyone wins fair & square

When you go into details you soon realize it ain't as easy as it looks. It's huge intellectual endeavor, takes a lot of time, patience, discipline, mental strength to comprehend, envision, to first construct, "project" idea in mind, do the prognosis and then stay focused, concentrated on work to achieve the final goal -- Get constantly stable & efficient results simply by touching and swiping on screen of a "tablet". Magic!

From my experience it's whole lot easier to prepare for and run the marathon.

Here, here...

One amazing aspect of working at Walt Disney Animation Studios is the huge amount of support and encouragement we get from our managers and the wider studio for publishing and sharing our work with the wider academic world and industry. As part of this sharing, the Hyperion team has had the opportunity to publish a number of papers over the years detailing various interesting techniques used in the renderer.

I'm feeling the same. Last year I came across this course in siggraph 2018:
https://cgg.mff.cuni.cz/~jaroslav/paper ... arning.pdf

Then I became very interested. And recently I even saw a WIP pull request that tries to bring path guiding into appleseed:
https://github.com/appleseedhq/appleseed/pull/2656

Having the author's implementation based on a well-known codebase (Mitsuba) is great, and I'm really looking forward to see it implemented in LuxCore
