Dear All,
I'm having issues with one of my spare time task. I'm using instances of a table and instances of light, so on the attached screenshot, the two tables are exactly the same, as well as the light litting them is the same, however, the one on the leftclears up really quickly, but the other won't. Even if I reach the max sample set to 10.000. I tried to use region render to clear that area, but it never gets better. I'm using PT kernel. The light is IES light. What should I change? Thanks for your efforts in advance!

Hi elsksa,
thanks for the feedbacks and to point on the weak points in my settings. However, specular depth is set to this amount to avoid the black areas behinde the glasses on the other parts of the scene (a lot of glasses next to each other, like in a bar).
I'll read the pages you copied me, thanks!
I accept of course if the wrong settings cause the issue, but then why it affects only a few object in the scene? This is strange for me.
