VRay Aerial Perspective

Having an issue where the VRayAerialPerspective renders fine using IPR but when rendering production through Adv I just get a solid colour never resulting in the geometry being visible despite playing with the values.

Max 2017, VRay Next with latest update 1.1. Any ideas?

Hm, can you get me a scene for this?

Apologies for the delay in responding. Just went to set up a reduced scene to send over and it’s working fine now. Maybe a restart did the trick. Thanks anyway.
