There are squares in my pictures. I do not know how or why this happens. Anyone who has experienced such problems?

First i tough it could be the denoise that made the squares, then I tought it could be collision between the lights or maybe the texture from the table. I have now tried to render without the denoise, I have removed the light from the candle and moved the table. I still can`t figure out what makes the squares. Same results every time.

enter image description here

I remove gloss from the lamps in the background (bookcase). It removed the squares, but I want the gloss on the table. Any way around this?

I now know that the problem is from the area lamp in the bookcase. When I turn the gloss off, the problem with the squares are gone, but I want the gloss though. So I remove the whiskey glass and glass that is in the bookcase. I remove the emissive from the spotlights and turn down the strength from the area lamps. But I still get the squares. I tried a different angle, but the results remains the same.

    $\begingroup$ Not sure why, but they seem to only appear as a reflection of the lights in the bookcase. The reflection of the candle and windows are fine. Check the setting for the bookcase lights. $\endgroup$

  • $\begingroup$ Perhaps not related, but there also seems to be something semi-transparent on the empty shelf of the bookcase. This may be right in the path of the reflected rays. $\endgroup$

  • $\begingroup$ Try to increase number of Bouncesin render settings. Or even try Transparency, Max and Min. $\endgroup$

    $\begingroup$ Can you share a simplified version of the file, just with the light and the table (with the images used as textures packed into the file)?. You can upload it at blend-exchange.giantcowfilms.com and then paste the resulting link as part of your question. $\endgroup$

Finally!

I had to increase the size of the area of the arealamp. i was set to 2mm or something. So the area was to small and messed up the light.

Want to give my thanks to Bfoot for helping me out! :D

Now I just have to redo every change I made to correct this :P
