Error after 2500/3000 frames of rendering

Cesium for Unreal
1

Hi,
I’m trying to render a 1-minute 360 video at 60fps (for meta VR handset). A plane takes off from the ground and flies over Verona, Italy. Everything starts fine, but it always (not every once in a while) breaks after a while, say after 2500-3000 frames. Am I doing something wrong?
I use Unreal 5.4, Offworld plugin for 360 rendering and Google Titles API.

You can see some frames here:

Hi @robisoft,

I haven’t personally seen these artifacts before, so I’m not sure what’s going on. But just to confirm my understanding, is the video being rendered from the view of the VR headset? If so, it’s possible that this is being affected by the smaller depth buffer on the device. Maybe playing around with the camera’s Near plane value will improve the rendering of these frames?

Hi Janine,
the video isn’t rendered by the headset, but directly by Unreal Engine using this plugin: https://offworld.live/
It’s a sort of 360 camera that I move along the path.
