VRay Render differences with RT Preview

[Tony McEvoy]

Hi,

Newbie question.
I've been doing a test using a Modo Texture that I use for TV screens etc. But don't understand the difference I see from the preview to a render. The screen box is placed on a green surface with no illumination other than the screen. The RT preview shows the surface illuminated by the screen face, but the Render shows no illumination on the green surface.?
The basic materials are all Modo.

Can you attach the scene, so I can take a look what's causing this ?

Hi Vladimir,
Scene attached.

It seems like a bug with the Irradiance Map, you can use Brute Force for Primary engine to match the results in RT.
We will log the bug.
