How to make custom masks in Quixel?

jacjac

So I've recently gotten Quixel and am loving it so far.
Currently working on a game with a few people which requires a custom mask for each model/asset to contain metallic, roughness, ambient occlusion and emmisive data. Each needs to output through different colour channels, eg. blue,red,green. I, for the life of me, can't figure out how to do this in Quixel, or even if it's possible?
We're working through UE4.
Please let me know how to do this, thanks!!

Well, you can output your different maps from quixel as different images, then combine them in photoshop, with roughness in the green channel, metalness in blue, etc, then export.

Quixel's export calibrations are scriptable.  The docs are right here.  I've made a few of my own custom export options for different ways I've packed channels int eh past, it's not too bad.
