Interesting note from second or your link, about indirect light though.
„IMPORTANT
Icon
When an emitter is excluded and does no affect a certain object, what is excluded is the direct contribution from that emitter, but its indirect illumination as it bounces off other surfaces will still affect the object, as once bounced it cannot be attributed to any particular source.“
Well, to be honest, I wished severeal times mureley, material should have the option to increase number of bounces, or change their count depending on counts (of course there should be a safety feauture to kill beams or certain types, or set all to default after a time limit)).
I can imagine these additional material features is easy to use, quite helpful for complex scenes and feasible with reasonable effort. Its not really a tweak its just changing probability of beams next step.

Re: DLSC test
That second part I am actually not big fan of. Inclusion/Exclusion should be a light property not object.. well in theory this could go both ways? Bounces or samples amount should always be handled by the renderer though/globally not per object.
But DLCS should work hand in hand with gi visibility of object, and this goes for future secondary gi caching too.
In theory it is very simple, but of course I have no idea how hard these things are to implement. One way or another, the more luxcore will be popular the more requests for this there will be.

Re: DLSC test
In my opinion light interacting is a matter of objects and therefore related to material.
Surely you may add some attributes to ray like number of bounces since emiitter and a stack with references to last object/material and a stack for last vectors. Vectors and object references may be used for denoising, removing fireflies.

Re: DLSC test
Struggle to render this with DLSC but metropolis + power give good result. Saddly DLCS with cache entry higher than 1cm ( at 5cm DLSC computing start to e to long so imagine 1cm ) lead to black artifact on the chair.

Re: DLSC test
As I wrote in another thread, the problem is likely to be the warm up samples count for cache entry, not the cache entry radius. Try to increase the warm up samples count (you can probably even increase the radius without problems).

Re: DLSC test
I think we need tooltips for DLCS setting ?Try to increase the warm up samples count (you can probably even increase the radius without problems).
Here are my test and it seem that i've to decrease samples count to have good result. high samples count + small Entry radius lead to white dot on chair (look like extremelly converged area) . don't really know impact on DLCS performance
Here is my light bulb setup and it work pretty well

Re: DLSC test
what is your light count for the scene in info tool?
Nice idea to use a 2D approach for a still.
