White dots

Hey, everybody. Help, while working in this scene, white dots appear during rendering (screenshot). Only in this location.

In my exp, those "fireflies" may come from multi or complex emissive lights in an interior scene... Under such circumstances, even if the setting of Firefly Filter is Enabled, you might still see them from the final render...

There seems quite a lot of emissive surfaces there in this bar, better check and see if you can optimize them... e.g. maybe you can hide some of the emissive lights (if they're not meant to be shown in your render), and/or replace them with spotlight instead.

Thank you very much. That really helped.

Did you use some Denoiser in the posted picture (e.g. embeded Post Denoiser in Daz Iray or Intel Denoise)?

Suggestion: Render at double the resolution. Don't spend more time rendering - so you'll actually have more white dots. But then user a free image editing program (eg GIMP) to 'denoise' the .BMP. And then save as a jpg in your intended resoltion.
