Updated and .....problem solved! Thanks.

By the way (changing topic here): when closing the Carrara scene before closing the Octane render window carrara crashes, every time.
No big deal since I can change the order of closing the windows but.....maybe there is a reason I don't see and I can fix ...

I'm trying to simulate a tilt shift effect on basis of a distorted photo and animated camera focal depth by keyframes.
When rendering a single frame everything works fine.
But when rendering as a movie in the carrara render room it doesn't work.
What settings do I miss?

Can't get the carrara shadow catcher to work properly.
A question of settings or is it not supported?
