V Ray Next not saving Mat ID or Object ID and other passes

V-Ray V-Ray for 3ds Max General
1

Hello, This is the third time I have this issue, I do a render on my Machine and V Ray next, do not create the Mat ID, Object ID, VRay ID pass.
IF I see the render buffer, the passes are there but if I open the saved file it is not there, in Photoshop I can open all the passes but these passes are all black.

I am using EXR file format, just like always.

What output type you have chosen for those elements? I suspect that Photoshop doesn’t work well with integer.

Actually, I am using the same workflow from 3.x nothing changed, this is a new scene, started from Scratch with V-Ray next. I did choose using Color with AA and still, it doesn’t save any ID map. I am saving the images as EXR just like always. I am in 3d Max 2019.
OK Corrections, it seems to work if I save separated EXR but doesn’t save any Mat ID if I save a single EXR with all the passes inside, just like I did with 3.x
This is frustrating.

Can you send us your scene to support@chaosgroup.com for investigation ? You can add this thread as a reference.
You can also add the multichannel EXR with missing MatID to the archive.
Thanks.
