Hi, I've attached an image I'm rendering. It seems to have patchs of noise that are rectangle. On the opposite side of the wall there are windows that are this shape. I'm using the glass material from the Corona material pack. Does anyone know how to fix this noise?

Thanks :)

You could try as burnin' has suggested. It's hard to really know without seeing the file. If you can share that with us, please feel free to use the Corona Support link in my signature below.

Can't really remove the glass for this project. Ticking the Thin (no refraction) button in the glass material seems to have fixed this. :)

Removing the glass or disabling refraction is still a workaround. It would be good to check the scene and find the root cause of this.
Maybe there are some environment overrides used, or some other non-physical effects that are causing the extra noise?

I also agree. If you're able to share the scene with us or a stripped back version, that would be great!

Thanks. Where do I send the scene to?
