Thanks dude

Found it
under
OCTANE SETTINGS
tick on radio button ALPHA CHANNEL

Hi Guys!
How can I tell my camera in C4D not to render the „DAYLIGHT“ and „ENVIROMENT“ Lights - within the Scene - for a clean alpha channel
I tried it with the Octane Object Tag but its still there.

There is one previous POST but the link leads nowhere.

Thank you so much
