EXR passes show up in vray but not in PS


Hi guys,
I’m trying to figure out what is happening.
I have 3 cameras in a scene, I want to render some RE as EXR 32bit for compositing.
For the first camera all worked good, for the other 2 cameras, I can see the passes only in Vray, but not in PS.
When I open the EXR, I see just a transparent layer (The grey-white PS checked texture).

Do you have any idea of what is happening?

Thanks a lot.
