Hello again veent_veent ,

Can you please also add the corresponding V-Ray assets (textures, proxies) that you used as we can't reproduce the issue without them. The easiest way to pack them is by exporting a .vrscene file as archive.
Please, whenever we request any files, don't attach the link to them directly on the forum. Email them either through our support system or directly at me ana.lyubenova@chaos.com

Best,
Ana

P.S. How to export a .vrscene file as archive?
1. Navigate to Settings/Paths & Sharing tab and enable the Export As Archive option under the V-Ray Scene Export Options
2. Make sure the problematic view is selected as Current View in V-Ray
3. Expand the Render toolbar panel and select Export V-Ray Scene. This will generate an archive file which can then be sent.

Also, can you let us know if you're using the most recent V-Ray for Revit version? And if not, can you update to it? (It can be downloaded from this link.)

Hi veent_veent ,

It seems like the issue is caused by the Primary GI engine being set to Irradiance map. That was the default value in the past and most probably it was transferred when you migrated your project. Set the engine to Brute Force as shown on the screenshot.

Oh, dear Anna and Teodora, sorry for my carelessness... when I copy file to my google drive and open it at another computer I forgot to reconfigure Vray settings. I don't know why but in this case settings get lost. But at least problem with ceiling now solved.
