MovieRenderPipelineCore Failed to load (Python)

Hello,

I am trying to use cmd or python to render a sequence using MovieRenderQueue.

Here is my cmd:

UnrealEditor-Cmd.exe D:\ThirdPerson\ThirdPerson.uproject
/Game/ThirdPerson/Maps/ThirdPersonMap.ThirdPersonMap 
-LevelSequence=/Game/LevelSequence.LevelSequence 
-MoviePipelineLocalExecutorClass=/Script/MovieRenderPipelineCore.MoviePipelinePythonHostExecutor 
-ExecutorPythonClass=/Engine/PythonTypes.MoviePipelineExampleRuntimeExecutor 
OutputDirectory="D:\" -game -Windowed -stdout -FullStdOutLogOutput

but it comes this error:

[2022.09.06-23.19.28:050][  1]LogUObjectGlobals: Warning: Failed to load '/Engine/Transient': Can't find file.

I am using UE 5.0.3, anyone could help? Thanks in advance!

@songks1 hi! Have you managed to solve this? I’ve met the same issue.

Figured it out. For me the problem was that I was using incorrect powershell command:

& "UnrealEditor-Cmd.exe" `
    "test.uproject" `
    <# level name: #> `
    DesertLevel `
    -MoviePipelineConfig=/Game/MRQ_Main_preset.MRQ_Main_preset `
    -LevelSequence=/Game/Resources/Spawnable.Spawnable `
    -game `
    -MoviePipelineLocalExecutorClass=/Script/MovieRenderPipelineCore.MoviePipelinePythonHostExecutor `
    -ExecutorPythonClass=/Engine/PythonTypes.MoviePipelineExampleRuntimeExecutor `
    -windowed -Log -StdOut -allowStdOutLogVerbosity -Unattended

Correct command (note that paths are wrapped in quotes).

& "UnrealEditor-Cmd.exe" `
    "test.uproject" `
    <# level name: #> `
    DesertLevel `
    -MoviePipelineConfig="/Game/MRQ_Main_preset.MRQ_Main_preset" `
    -LevelSequence="/Game/Resources/Spawnable.Spawnable" `
    -game `
    -MoviePipelineLocalExecutorClass="/Script/MovieRenderPipelineCore.MoviePipelinePythonHostExecutor" `
    -ExecutorPythonClass="/Engine/PythonTypes.MoviePipelineExampleRuntimeExecutor" `
    -windowed -Log -StdOut -allowStdOutLogVerbosity -Unattended
