Okay, I agree, it is still not perfect but it is an improvement.

If there only were the option of irregular spectrum input for point lamps..
(I have the feeling this option would add some tasty extra, especially for interior space images.)

DLSC now automatically estimated the best radius if lightstrategy.entry.radius is set to 0.0. So it works like PhotonGI and there is no more need to worry about picking the right radius by hand.

Could we test it just downloading the next daily build?

Yes, if you just set the radius manually to 0.0 (if it is allowed by BlendLuxCore). However, I have not yet changed anything else (I started from more obvious things to borrow from PhotonGI): it is a only "quality of life feature".

P.S. Has anyone a simple test scene showing the splotches problem with glossy material ?
