I'm not sure if this new hybrid back/forward feature would be an exception to this rule?
Nope, it isn't.

Re: Hybrid Back/Forward path tracing (aka BiDir without MIS)

So this scene is actually no valid test scene for the new hybrid solution, which I should have figured before :oops: If you add a couple of walls, it is a good test scene: - Path tracing => mostly fireflies - Hybrid path tracing/BiDir => good caustics on walls - Something able to render SDS paths t...

Re: Hybrid Back/Forward path tracing (aka BiDir without MIS)

Important note: because Hybrid Back/Forward path tracing has still a strong path tracing component, it is often useful to disable the light visibility in specular paths to avoid many fireflies. This fact is was hidden by the bug I have fixed. How to disable the light visibility in specular paths? I...

Re: Refreshing the LuxCore Wiki

The main reason why we are considering to use a different wiki service than the current MediaWiki is that the MediaWiki syntax is obscure and cumbersome to learn and use. The new wiki service should offer a simple and standardized syntax, for example Markdown. It should be easy to contribute to the...

Here it is (220 MB): https://drive.google.com/open?id=1vS5v1 ... HYGO6DegDX
I get all the right highlights:

Yes, thanks.

Side node: Hybrid uses always Metropolis sampler for light paths (it is just always better, doesn't make sense to use anything else) so it is better to use Sobol with GPUs (it will be used for the eye paths).

Re: Hybrid Back/Forward path tracing (aka BiDir without MIS)

P.S. the next step is hybrid GPU path tracing with CPU BiDirVM ... remember my axe :mrgreen: That bidirVM will actually render SDS right? So at that moment the caustic cache will no longer be needed. Caustic cache could be modified to render only SDS paths so Hybrid+caustic cache produce the comple...

In your rendering I see a bug I need to fix: "ES*L" paths (eye => any number of only specular bounces => light are not rendered at the moment in Hybrid Back/Forward).
Have you managed to fix this too?
Yes, the fix is part of my last "infinite lights" fix.

Re: Hybrid Back/Forward path tracing (aka BiDir without MIS)

While it works already great out of the box with the Wallpaper scene, in my pooltest scene everything is black apart from the tiles. Looks like infinite lights are not supported yet I should have fixed this problem (see above). unlike BiDir no caustics are rendered in the water. Like BiDir, no caus...
