Probuilder Object disappears depending on camera position

Hi,

I made some walls with probuilder. Now I have the problem, that depending on the camera position the walls are not visible anymore.

Here you see an example:

That happens in Edit mode and with the game mode camera as well?

Any idea what could be wrong?

Thanks in advance
Frank

Since it happens in both editor mode and game mode it makes me wonder if probuilder is not updating the bounding box appropriately. If that’s the case, it would be a probuilder bug and I’m not sure how to fix it.

This sounds dumb, but have you tried simple things like unloading the scene and reloading it, or restarting Unity?

yes, I tried realoading the scene, restarting Unity and many more. Only thing that works, was to create a new separate object for this part of the walls.
