Direct Light cache: how to avoid splotches?

[Sharlybg]

Hmm.. So apparently, corona's own new light solver (that helps with the same situations as this direct light cache should) is still not working 100% and is disabled by default. Cycles's lithttree is also still not implemented(I'm not even sure if it is being worked on still). So this makes me think if there is a fully working and tested solution for huge amount of lights..?

Vray adaptive light

while not a production renderer and more just a hobby project, psychopath renderer by cessen has an implementation of a light tree. this was also the first renderer I saw implement an open source version of a light tree to aid in direct light sampling. he did a blog post or 2 about it on psychopath.io, and it was even good enough to earn him a nod in an academic paper on the topic.

Done, this is direct light only:

and this with GI:

Impressive what are the DLSC settings for this ?

The defaults, I only raised the warmup samples because the default value (12) is really low. I'm thinking to rise the default.

P.S. for the record, it is a scene with 11,000+ light sources.

11k lights sources .

How can we update this new code ?

Please Dade can you test the new code with AMD and my problematic scene here ? :

I think that the sign on the left is the main problem.
I added on the fly cause I had to finish in hurry and I didn't think to optimize it.
The lights on the track on the ceiling should fine. The emissive material is assigned to just a triangle.

Could you confirm that , expect the logo sign, the lamps are well setup?

EDIT: I saw that on the floor (visually on the bottom part of the image) there is some bright pixels. I can't understand if it's correct or not... the mesh under the fur should have a dark material assigned.

It is working fine for me (but it was also before with my Linux + very old (stable) AMD drivers I never upgrade ... because they work).

To test the new code you have only to replace the pyluxcore.pyd file on your HD with the one included in the daily build: https://github.com/LuxCoreRender/LuxCor ... tag/latest
