Objects move to scene center when rendering

[arno_saar]

Hi,
When rendering, all the scene contents move to scene center 0,0,0; but everything is fine in the viewports.
This only happens when rendering. Nothing is animated, a new clean scene, only two geometries and a v-ray light source.
It doesn't matter if I use single frame rendering, IPR or viewport integrated IPR.
I'm using 3ds max 2024.2 and currently V-Ray 6.2, but had issues already with 3ds max 2024.1 and latest 6.1 beta versions.

Some further testing showed that objects only move on X and Y axis, but not on Z axis.
Also lights are somehow not affected, but cameras are.

This happens with a brand new scene? After restarting Max?

Sometimes it happens just "randomly", but what certainly brings out this behavior is when opening a new or existing max scene while another max+v-ray scene is rendering. Then the following opened or created max scenes are also possessed by the same issue.

You may have pre-render callbacks (not of our making).
I tried what you mentioned but it doesn't reproduce on my side.

Is your scene an xref bound to a helper?

No, I got errors already from a brand new scene.

Although I got some progress by deleting: C:\Users\<username>\AppData\Local\Autodesk\3dsMax\20XX - 64bit\ENU folder - to reset 3ds Max user preference settings.
Now at least so far, scenes are working. But when I dare to open new 3ds max instance while another one is rendering, I still get the same error in the new opened max scene (doesn't matter if new or saved scene).
