Can someone explain what should be found in the background AOV. I am quite certain that in earlier versions of Arnold 5, I was using the background AOV to store; for example a skydome and holdout of any geo in front of the skydome. However, now using MtoA 18.104.22.168 the background AOV is empty and skydomes are now found in the emission AOV. Is this a bug? or now the intended outcome?
