C4D Floor and Background object

Hey all, anyone know why i cant get the native Floor and background objects to work with Corona in C4D. I’m applying a Corona material to them but only ever get a black background.

Don’t really want to be putting extra geometry in the model for a background if i can help it.

Cheers

Sorry, the short answer is you can’t. this feature hasn’t worked since I got into alpha testing this engine.

Just use a plane with no subdivs,
