Tile loading issue when recording panoramic videos with cesium for ue5

[111111oct]

I encountered the issue of tiles not loading when using Cesium for UE5 to add level sequences for rendering panoramic videos (exporting sequence frames). This means that when the camera moves to a certain location, the tiles disappear or are missing, but when the camera leaves a certain location, the tiles will load again. When using UE5sequence sequence to record regular videos normally, this problem will not occur. Is there any solution? Thank you very much

Hi @111111oct, welcome to the community!

Can you show us the problem you’re seeing, perhaps with a screenshot or video?

Based on your description, it sounds like Cesium for Unreal may be having trouble determining the parameters of your camera, perhaps because it has a very wide field of view. If so, you may have some luck by changing the following options on the Cesium3DTileset:

• Turn OFF “Enable View Frustum Culling”.
• Turn ON “Enforce Culled Screen Space Error”.
• Set “Culled Screen Space Error” to the same value was your “Maximum Screen Space Error” (16 by default)

Another option is to use the CesiumCameraManager to give Cesium for Unreal custom camera parameters. Instructions for setting that up are here:

Tiles not loading at edge of render area

Much to our frustration, Unreal Engine provides us with no way to determine the dimensions of the output render when using Movie Render Queue, and thus we can’t determine its aspect ratio. So if your video has an aspect ratio other than the usual 16:9 ratio of 1920x1080, you can end up with artifacts like this. The only way around this currently is to use the CesiumCameraManager to define a custom camera that reflects the position, orientation, width, and height of the actual view used to record…
