Hi, Im new here. Im trying to render a office ( I cant do it on Best quality cause the render time is way to long (+10hours to get to 15%) I play with the custom settings and get high values on most of the things, but when the render its done, I’m having this issue with those White spots on the walls. I check the paint (it is regular White paint). I check the lights ( Revit fluorescent downlight and just using one long light. Anybody have came across the same issue. Please help.

Regarding speeding up render time. Have you tried rendering to the cloud. Its much quicker - 20mins render time tops. Free if you are a student.

Regarding white spots. Have you tried adjusting your exposure settings in render?

Yes, I check the exposure and play with all the settings. The weird part is I remove the paint on walls (because I use paint tool but the material was different) and it kind of solve the problem, but I still got some spots.

What i do was using natural and artificial light, so the natural light fills the room and covers the white spots.

You need to turn on Daylight Portals. Yes. It will take more time. But this only works if you have openings in your model and it's daytime. Otherwise, Artifical only is enough.

And avoid rendering at 'Best'. High is generally enough unless you plan to render a good quality exterior. Also check the size of your image. Are you rendering at 300dpi? Or rendering at screen size?

You can also increase the light intensity in your light families.
