PhotonGI cache

[lacilaci]

I'm basically looking for a "flame bait" LuxCoreRender Vs Cycles and I was thinking to this scene because I was under the impression it was available for download. The scene itself is not particularly important. Just to have a significative banner for alpha0 release

I'm in general also looking for more scenes to add https://github.com/LuxCoreRender/LuxCoreTestScenes

Tweak the benchmark scene for 2.2:
300 samples + pgi + oidn

this gives final render quality +/- 12x faster (for me) compared to 2.1

give the scene for people to do their own comparison. 1 minute interiors is pretty big deal on it's own.

65 sc on R9 390 ! Note that this R9 Gpu is equivalent of Nvidia GTX1060.

PGI look So dark on Nakagin capsule scene . Or don't have a given lastest fix

Path 5mn R9 390 + Titan Black + i7 8700k

that's a big difference! How does the debug view on photons look?

How PGI flickering looks on still (with animated & static seed for sampler)

For animations, we are going to need the capability to load/save the cache from/to file, it is something I still need to write. There is also the fact that the cache is not currently deterministic (due to multi-threading), it may be something I will have to change too.

It may be a factor only if you are using caustic cache (not if it was an indirect cache only rendering).

Talking of game changing features

We will need to spread a bit the "word" after the release of alpha0.
