How to pause everything except the post process materials

I’d like to pause then unpause everything but the custom post process material from blueprints.
I tried “SetGamePaused” but it also stops executing the delay node so never gets unpaused, plus the materials stop as well.
I saw “SetTickableWhenPaused” but that’s for actors.

I don’t think I quite understand, Are you doing something in the material like a panner or some effect you want to keep going?

If that’s the case in the time node inside the material editor you can check “ignore pause”

Exactly, my goal is to freeze the world but have materials keep on working.
Oh I totally missed that flag, thanks!
