Ouuu!!!
Photorealism will remain the same?

Yes

In scenes with many light sources, this method should be vastly superior to the current generic light strategy.

This method is also unbiased.

So with LC1 we remove light strategy completely (no need to keep it) ?

appleseed uses a many light sammpling strategy, it works pretty nice.

This is the first rendering with DLSC enabled:


It can do a huge difference with many local lights as expected but the results can be good also in some really simple scene. Disabled:


Enabled:


And as a bonus some nice "little spheres anywhere" debug rendering:

DLSC is implemented like a new light strategy. It can be selected like any other strategy.

you're reaching striking result. I estimate a jump 8X or 12X (woawou ).

Is there any reason to keep the older light strategy ? Or do you think there are some lighting scenario where older light strategy could perform better ?

The DLSC adds to the startup time, in more complex scenes it needs a few seconds to build.
So the older light strategies will still be useful if a scene does not benefit from DLSC and/or if you need very short render times and the startup cost is higher than the payoff.
At least that's my guess.

Yes, for the above reason, it is likely to not to be the default light strategy too.

P.S. it costs memory too (to store the cache).

Simply fantastic!!!!

My showroom test scene is warming up

So, with scenes with only an hdr will not be benefit?
