VfR vb functions - AddVFBChannelByName

[Simontam]

I'm using the VfR plugin to access scriptable functions within my script. Specifically I can't seem to get the function AddVFBChannelByName to work.

I want to enable the Shadow channel by doing the following:
Dim vro
Set vro = Rhino.GetPluginObject("V-Ray for Rhino")
if IsObject(vro) then
vro.AddVFBChannelByName("Shadow")

This doesn't seem to be working, likely because I don't have the right name. What are the official names of all the channels such that this would work?

Thanks,
Simon

Is there really no answer here? Clearly the API exists and I'm sure someone is using it. I just need to know what the actual names are of the channels to make this work.
