Just by the way... here's how it looks faked in cycles
They are not exactly hard to fake in LuxCore too:

with the not so small difference that they are true caustics instead of faked one.

It is exactly the contrary according the paper (and it makes sense).
You mean the paper or my idea makes sense? :)
The paper :D
To further elaborate: the paper makes sense in the context if this infinite angle reduction ... in practice it may be different, I can try that.

Re: Path Space Regularization (aka the solution to SDS paths)

So if I currently set the pathspaceregularization.speed to 1... and let's say scale to ~1(or whatever value). Won't I end up with the same result as if mollification was removed? Yes, exactly (indeed, the .speed parameter has been removed in the very last sources). And if that's the case, then the ...

Re: Path Space Regularization (aka the solution to SDS paths)

That's what I've been thinking about the last few days. Doesn't PSR mollification have to happen during MLT small mutation ? Large mutation phaseses dont know about each other, so an old phase wont help the next to find a path... I mean, the reduction of the mollification bandwidth has to happen be...

laser .ies file for the light.
LuxCore has true laser light source, use that.

Re: Path Space Regularization (aka the solution to SDS paths)

Yes but that is a Metropolis problem, not a PSR one.

Re: Path Space Regularization (aka the solution to SDS paths)

Can we compute the "minimum useful angle" for a given scene and film resolution and use it as lower cap? Yes, this was my initial idea however, if you use a cap, on the long run, any rendering done before the cap will fade out. For instance, let's say we spend 1,000 samples to reach the cap, and th...

Are eye paths and light paths connected when using Add Light Tracing?
Nope but it would be useless because the same paths are better rendered by normal path tracing.

It rather seems to me, that they are separate renderings which then added together.
Yes, they are just added together.

One thing I don't understand is, is this inability to hit round surfaces (or faces at an angle) a limitation of metropolis or is it a limitation imposed by PSR?
It should be more a Metropolis problem than PSR (may be accentuated by the very narrow angles used by PSR).
