How to properly export Cryptomattes for Photoshop? How to properly export Cryptomattes for Photoshop?

Seems I cant find the right thing on the internet so far.

In Modo, was just one click to get the " Color ID Pass" 

I've tried EXR multi layer and it doesn't work, I just want a clean ID pass on material/object.
It's working fine using OpenEXR multilayer. You just have to install exr.io for the photoshop side of things and setup your passes in the compositor using the cryptomatte node and a file output node before rendering.
