What is in the scene(s)? Are they interior scenes? How are you lighting the scene? How long are they running, and what is the finel sample count?

Hi Richard,

It's an interior pre-built scene from Stone Mason (full details below), it takes around 20-30 minutes to complete the render using IRay and I have tried Rendering with and without one of the pre-set cameras - both come out grainy. I'm not sure how I go about finding the sample count - i've attached a screen shot of the render being processed.

This https://www.daz3d.com/starship-bridge ? I don't have it, so can't test, You are using the Iray version (it says it has both)? How does it look when it stops? What is the Environment Modse set to in Render Settings?

I think I added an atmosphere prop to that one,removing it should get rid of some of the grain,

Hi Stonemason,

I cannot seem to find an atmosphere prop - do you know where I can find it?

Thanks,

John
