Yellow spots appearing after the render is completed

[jet1990]

Hi All,

This has happened a few times to me now. After the image is done rendering i open it up and it appears with all these yellow spots/ blotches all other. Any ideas what this is?

I cant share any scenes as i am operating under an NDA for a big client.

thanks

Hi,

It looks like something that can be caused by transparent materials and caustics, but without the scene it is difficult to say.

What are your render settings? Are you using Custom Control?
Does the image look fine in the preview window?

Im using quite a bit of cloudy plastic material in the scene.

Interior mode is on.

Using max samples to renders.

Caustics aren't on.

Image is fine in the preview window and the preview of the render. it seems to be occurring once render is completed and it saves the image.
