What do I use instead of a Compositing Tag?

[infoARNXD]

I'm new to Arnold. What do I use instead of the Compositing tag to knock out the background for a PNG? I would normally use the C4d compositing tag and uncheck "Seen by Camera" so I get all the correct lighting on the subject but minus the background. I've searched everywhere to find info on this but couldn't find anything.

You can assign an Arnold Parameters tag to your object and uncheck the Camera visibility flag.

Many thanks! I knew it was hiding somewhere.

For some reason it still doesn't work. I'm guessing it's something to do the Arnold Sky? 

Is there a way to knock out the background without deleting the sky?

Right, if it's a light (Arnold Sky is a skydome light), then you find the visibility flags at the bottom of the light attributes, not in the Arnold tag. Just set Camera to zero.

Perfect! Thank you!
