Automated MovieRenderQueue Failed due to Cesium Error

Cesium for Unreal
1

I am trying to automated the video generation using Movie Render Queue with Cesium tileset present in the Level.
CMD: "C:\Program Files\Epic Games\UE_5.2\Engine\Binaries\Win64\UnrealEditor-Cmd.exe" "F:\..\Game.uproject" L_WaikikiWithOcean -game -LevelSequence="/Game/3DGame/LevelSequence/LS_OceanView" -MoviePipelineConfig="/Game/3DGame/LevelSequence/Config_4k" -windowed -Log -StdOut -allowStdOutLogVerbosity -Unattended

BTW, I was able to generated same level-sequence video in editor manually. Also, when I use similar cmd to generate video with Level without CesiumTileset, it didn’t throw error and video output was generated.

Unreal v5.2.1
Cesiurm v5.2.0

What version of Cesium for Unreal are you using? The Epic Launcher doesn’t report the version correctly (there’s no such version as v5.2.0); you have to go to Edit → Plugins → Geospatial. Does the rendering work without crashing if you invoke it from the Editor instead of from the command line?

Its Cesium 2.2.0

In most times, I am able to render without any issue/crashes. In few run, I get error message regarding GPU crashes.

The message you shared above isn’t a “GPU crash”, it’s an access violation on the CPU. Are you saying that in the Editor it usually works, but you sometimes get a different error? If you want help, you have to provide thorough, detailed information.

My major concern is of the error due to “UnrealEditor-CesiumRuntime.dll!ACesium3DTileset::PostLoad()” which can be found in full-log of my first post.
Steps to recreate the issue:

  1. Create Empty Level
  2. From Cesium plugin, add Blank 3D Tiles Tileset and CesiumSunSky
  3. Configure Cesium3DTileset’s Ion Asset ID and Ion Access Token
  4. Configure Georeference lat/lon to Honolulu island.
  5. Add CineCameraActor and LevelSequence.
  6. Track CineCamera in LevelSequence, after finalizing shot.
  7. Configure render setting in MovieRenderQueue and choose the preset.
  8. Save Level, LevelSequence and MovieRenderQueue preset. Close Unreal Editor.
  9. Run Unreal-Cmd with ProjectName.uproject, LevelName, LevelSequence-Path, PresetName
  10. Low-Quality preview of MovieRenderQueue does not appear and Unreal closes with error message in console.

The GPU crashes are something which is different than my concern which I posted in my first post.

You still haven’t answered the question in my first response above:

Does the rendering work without crashing if you invoke it from the Editor instead of from the command line?

Yes, rendering work without crashing if you invoke it from the Editor instead of from the command line.
