Hi Hans,
You may want to read this post for info on how to share pictures and or files.
Thank you, I did that, attaching the files now... two pictures showing the problem and the project file (large!)
- The forum has 18 posts/threads on "white spots" and 10 on "black spots". They may offer some insight in the problem.
I'm sorry if there were already other answers... I tried a search, but I think all I found was a suggestion to move the objects around a bit, which didn't work for me. This appears to be like a non-graceful overflow of some sort when there are points too bright... But then, in one of the photos you can see the dots also in the mirror, so who knows.
- Q1 and Q2 rendering depends on hardware, and your video card may influence results. Q3 and Q4 rendering depends on software and should produce identical results, even between different computers.
Indeed... That's why I ruled out driver problems, and I did point out that renderings on two different machines gave the black spots in the same places!
- You may want to experiment with the settings of the afflicted (furniture) models. Changing between Unchanged, Matt and Shiny may (or may not) solve the problem.
Yes, changing things to matte does prevent objects from getting dots; but 1) some objects I want to be shiny; 2) lights often have the spots, and they don't go away just setting the light to matte. That too makes me think the program doesn't handle well what happens when it renders a very bright point.
- You may want to use Q3 (which doesn't have the spots) and make an extra large rendering, which you then reduce in size to obtain the same quality as a Q4 rendering.
Would that really be the same quality? Same shadows and lighting? And how much bigger should it be, would 2x on both directions be ok, to be then resized with a cubic resize?
- You could share your design, so we could have a look at it and see if we can reproduce, isolate, or solve the problem, and/or offer a workaround.
