Ambient Occlusion VUE vs Luxology settings

Hi everyone,

This has been highlighted in an older posting, not sure if a solution was found.
I am trying to copy/re-create the same settings (in Connect Edition VUE)  that Luxology (V8i) had under Ambient Occulsion. I really like this render setting.

Comparing settings, it seems that to produce the monoclour/black and white image,only the Alpha channel was exported? 
In VUE it is greyed out, and I cannot untick Color&Aplha?
What is the workaround please?

thanks...
