Hi everyone,

I’m currently working on rendering a very complex space… I’ve been stuck on it for several weeks now.

It’s a windowless restaurant with segmented mirror cladding on all walls and a fully mirrored ceiling. Aside from the floor and the tablecloths, almost everything is reflective: chrome leather sofas, silver fabric curtains, a brushed stainless steel bar and baseboards, etc.

There are also many light sources: spotlights, chandeliers, lamps, and glass wall lights.

The issue is that I’m getting a lot of noise (or fireflies). The spotlights seem to make things significantly worse, but when I remove them, the lighting becomes very flat and honestly not very appealing.

After several weeks of testing (sampling settings, light intensities, material tweaks…), I still can’t seem to find a satisfying balance.

Does anyone have advice or experience with this kind of ultra-reflective space with so many light sources?

One more thing: the infinite mirror reflections are creating a sort of black horizon in my render. Is that something that would happen in real life, or is it just a rendering artifact that could get improved?

Thanks a lot in advance

I'm unsure which Maxwell version you're on, if v5, try using the Denoiser which has an option to remove fireflies. With all the highly reflective materials it's a complex scene. Maybe also look at reducing the camera resolution to lower the file size being generated so it doesn't bomb-out as your RAM gets used up?
I came across a tip a while back which suggested including opening(s) in the model to allow light rays to exit the scene which reduces the light rays bouncing around for longer periods. This might require turning off the wall(s) behind the camera, and not shown in any reflection off the wall mirrors?
Hope this helps.
