How to extract Cryptomatte mask from a VRay-rendered EXR and combine it with the Vantage-rendered EXR?

[hill_lam]

Is there a way to extract the Cryptomatte mask from a VRay-rendered EXR and combine it with the Vantage-rendered EXR?

This way, I can edit the EXR rendered by Vantage in the VRay VFB and easily add Cryptomatte masks.

I tried using the Exr-IO plugin in Photoshop to open the EXR rendered by VRay, drag the Cryptomatte Raw Data layer into the EXR rendered by Vantage, and save it. However, it failed, as the VRay VFB couldn't recognize the Cryptomatte mask.
