Opacity map causing weird noisy edges in z depth pass

Hey everyone,

I’ve been using quixel megascans in a couple of engines and I’m having this issues with the z depth pass in each engine. It seems like the opacity map gets read but it doesn’t behave the same way as it does in the beauty pass? Take a look.

This is from redshift.


This is from Arnold. (I placed blue behind so you could see the black)

Any thoughts?

Thank you!
