MutliChannel EXR confusion in the VFB

[BeneZ]

I have found out after long research, that I can only store all channels into a file at the "Vray" Tab > Frame Buffer "Vray raw image file".

Does it mean that the "save as" in the Common Tab is obsolete?

I don't understand why this is not all at the same place and better explained

And then I'm getting a warning, because I have disabled the standard common output:



I had basic "common" output (Render Output > save file) unchecked.
Thanks

If you render using Vray's tab then you can safely ignore that popup.
It's a core part of Max, so you can still use it to output other file types.
