Title: HDR Peter Guthrie very noisy
Post by: anderson18 on 2016-10-29, 14:45:22

Hi all, I have problems with an interior render, I tested two HDR images as an environment for an interior scene with HDR higher quality (peter guthrie) I get too much noise difficult to remove while the other HDR is simpler not so much noise. Can someone explain why this happens? Thank you.

Could you post example images?

This doesn't solve your problem, but I had the exact same problem the other day, only in V-Ray. I turned off lights and pushed up subdivs, but nothing helped until I turned off the HDRI environment. Maybe some of his HDRI's are just noisy?

This might happen if the HDRI is contrasty - for example if it has dark clouds and a small, very bright sun. But even in that case, it should be possible to get noise free image. Maybe you should change some material settings and use portals in your windows? See: https://coronarenderer.freshdesk.com/support/solutions/articles/5000501983

By the way, an example image would be great too!
