Black/White Matte for Keying

Hi,

I have a black/white matte (Z depth) as a picture that I want to use for keying.

I was not able to manage that in Fusion (e.g. use it as traditional mask).
Is there a quick way to make it work?

Change the Channel setting to Luminance in the settings of the node for the mask instead of Alpha.

Great! Works! Thank you very much!
