[cielbleu]

Hi all, I am newbie on vray and am trying to do an interior render in white. there are black dots all over the ceiling and on the floor, I spend half of day try to make changes on setting, but it just stay the same if not worst. Can someone enlighten me what I have done wrong? ??? ???
Thanks in advance.

Lower your Image Sampler Adaptive Subdivs to 8 maybe and the Noise threshold to 0.01

Also in the Irradiance maps to -3-1 and 60/30

Hi Leobonilla, thank you for you quick reply.

Sorry, I am not very good at vray.... when you say lower the Adaptive Subdivs and noise threshold settings, I am not sure where they are....do you mean the max subdivs sample of the adapative dmc setting ? or the the dmc sampler setting? It would be great if you can point me where it is. Thanks

Hi, you have insufficient light in scene. Before doing anything in Vray settings, you should increase the light.

Also double check that you don't have overlapping surfaces.

Best
