VrayEnvironmentFog to show only outside, not inside of the building

[MikkoK]

Hi. I'm doing a short animation where the camera moves from outside to the inside of a building. I have used VrayEnvironmentFog to make some atmosphere but I would like it to show only outside, not inside. Is this possible? Also the building has curved walls so I can't use those Atmospheric gizmos.

Thanks in advance

You can also use a custom object as a gizmo, where you disable its "Visible to camera" option prior.

Oh, okay, I didn't know that. It works perfectly. Thank you!
