warning: Failed to create VFB2 user interface.

Im trying to render a vrscene with standalone cmd prompt but get this error
warning: Failed to create VFB2 user interface.

So I dont get to see the VFB as its rendering
I do have the -display=1 in the code.

It does render fine but just cant see it until it saves the file.

It never used to be like this all latest install builds for Maya 2020.4

This issue has been around for a while and we are working on a fix (already developed in the V-Ray for 3ds Max nightlies). Until then, no preview will be available, I'm afraid.

[stezza]

Thanks for the feedback, is it available in the Maya nighlies?

[hermit.crab]

Not quite yet, but its implementation is in progress.

still no news on that problem ?

Same problem on vray 5.2
"Qt version (5.15.2) does not match the expected version (5.12.9)"

Same problem on vray 5.2
"Qt version (5.15.2) does not match the expected version (5.12.9)"

That's usually caused by a bad install or bad environment variables (if using .zip installation). Reinstall / Reset environment variables and try again.

I'm using zip instalation. The environment variables are set correctly, checked several times, but the error is still present.
Everything is work fine,except the framebuffer

Have you set the Standalone specific ones as well? Also, any other warning/error messages?
