Cryptomatte in Fusion

[studioyf]

Hello all,
I've been exporting Cryptomattes lately, which is an awesome features.

I would usually do my compositing in After Effects, but for a few reasons I'm doing this one in Resolve / Fusion.
I have an issue when importing Cryptomatte (with the Cryptomatte plugin from Reaktor) :

this is how it shows up in Fusion

It just shows 2 colours rather than a nice colour separation for all objects.
I've seen a fair amount of tutorials with people importing Cryptomatte in Fusion from Redshift / Arnold / Houdini, and it looks pretty good.
Not sure if it comes from Octane itself ? Or the Fusion plugin ?

Anyone had any luck importing them in Fusion ?
thanks
