Background object?

[EditRoom]

Hi!
#1. Any ideas how to make the HDRI not seen by camera? (Normal way to check oft the traffic light doesn't work.)

#2. Any way to use some kind of background object? (When lighting a scene with HDRI and having just a colored background that doesn't influence the lighting)

I'd like to know the answer to your 1st question as well. I tried the Compositing tag to hide the Sky Object but it didn't work.

My workaround was to put a gigantic plane in the background (covering the HDRI) and then put a standard Cinema 4D material on it, because - as far as I understand it - those get ignored by the Octane render engine and they also don't affect it.

Compositing tag is not our tag, as i said.
in Kernel settings, enable alpha channel. Put a background object with standart material which has a image texture. And start render.
Also new sdk has a few option for visibility, i'll check for possibilities

samples pack has scene:
background_and_matte.c4d
check it please

In the kernel settings tick alpha channel and un-tick keep environment
(http://render.otoy.com/manuals/Cinema4D/?page_id=82 settings are here)

This will mean you get full alpha where the HDRI would normally be shown.
Is that useful?

Thanks
Chris.

Yes, FooZe and aoktar, that definitely is useful. Thanks!
