I’m encountering an issue when rendering animations (Movie render queue) out of Unreal Engine (UE5.5) with Cesium tiles loaded into the level. Specifically, the render seems to get stuck during the motion blur phase of the render process.
Notably, when I render the same animation sequence without any Cesium 3D tiles present in the level, everything renders as expected without any issues. This leads me to believe the problem may be related to how Cesium tiles are being handled during the rendering process. Cesium is updated to the latest version
Hi @matija_v,
When Cesium for Unreal detects an active Level Sequence, it switches into a mode where it waits for all tiles to load before returning from the Tick method. This makes sure you get a high quality rendering with all necessary tiles loaded, but it does take some time.
However, if you’re seeing it hang indefinitely, then something is wrong. In that case, can you tell us what tilesets and raster overlays you’re using? One possible explanation is that one of your tilesets or raster overlays is making a network request that never comes back.
If you can give us step-by-step instructions for reproducing the problem, preferably starting with the Cesium for Unreal Samples project, we can more easily investigate and debug.
