Where is VolumeCollector --> Emission Intensity in Anrold 5?

The Volume Collector in Arnold 4 had an attribute called emission intensity. This attribute is gone in the STandardVolume in Arnold version 5. How do I achieve the same thing in Arnold 5?

I have been able to *kinda* work around this issue by eyeballing the value in the color of the emission, but I find it frustrating that Arnold removes attributes from shaders without explanation/docs on how to deal with these missing attributes.

if you want to use the legacy aiVolumeCollector, just type in script editor (Mel)
createNode aiVolumeCollector
or you can tab search aiVolumeCollector in the Node Editor

Hey Lee, I thought so too, but I can't crank that value past 1. What I am trying to achieve is an effect like color accumulation in the Maya Hardware render.

You could also try the Volume Sample Float and Volume Sample RGB shaders.
