Title: Corona VFB disapears
Post by: Naxos on 2025-05-15, 18:26:43
Hello there,

Not really a bug i think, but a strange behaviour.
With a scene (only this one, for now), i can start interactive rendering like a charm, but when i start final rendering, the VFB disapears.
And when i try to click "show VFB", it is the Max's default ugly VFB that comes up.

Of course, i've checked in the Corona's system settings, and "Corona VFB 2.0" is choosen.
I've tested with "Corona VFB", same thing.

Any idea ?

[edit] : Corona 12 update 2 hotfix 1, 3dsmax 2025.3, windows 11.

I was thinking maybe the vfb is on second screen but if 3ds Max vfb shows up on clicking "show vfb" then something may have gone wrong. Is it happening every single time in all scenes across? or in some specific scenes only?

For now only this particular scene.

I could render, and i know i could merge scene for testing, but i was wondering if there were some hidden param or some simple solution to this.

The only thing that controls that is the VFB type in Corona system settings and Show VFB in Render Settings.
Have you checked those? Have you tried changing and then setting to the original values?

Sorry, i've finished this project and went onto next one.

Only this only scene did that.

If the issue is related to a specific scene, it would still be helpful if you can please include that scene in your support ticket. This will help us reproduce the problem and identify any underlying issues we can address in future updates.
