Quote: "But I'm guessing that Advanced terrain can only update culling to 1 camera at a time."
That's my guess too. I'd assume it updates for camera 0 (or the current camera - I'll try to find time to do some tests or, better, ask Mike Johnson who should know
). Of course that should also work for the refraction camera as you say - it's the reflection camera that should be wrong which might explain some of the problems I'm having.

Seems quite likely in view of our experiences.
Quote: "It depends what the user wants. If you look at the demo there are only 2 cull updates. One before the refraction and main camera gets rendered (as they are in the same position and point the same way) and another before the reflection camera renders. The user is able to update LOD and Culling for each cameras or make cameras share cull/LOD updates if theyre in the same position.

Thanks. That makes sense.
This has been a useful discussion and I now have a clear idea of what to check next in my demos. Thanks.
Anyway, I doubt the update terrrain command will help AT that much. Have you got any comparison results for FPS with and without update terrain for your demo (ignoring the culling difficulties for the moment)? I'd do it myself but don't have BT ... yet.
