Cant import GLTF Animation

Really impressed with GLTF support so far!

Unfortunately having issue importing animation.

Just trying to roundtrip standard Manny walk animation.

Steps to reproduce:

Export Manny walk animation to GLTF.
Import that gltf into a different directory.

Error Log Not Much Help:
LogInterchangeEngine: [Pending] Importing
LogInterchangeEngine: [Pending] Importing
LogInterchangeEngine: Error: [Failure] Import Done
LogInterchangeEngine: Error: [Failure] Import Done

Thanks again for any help/advice

what export fbx option did you check?
are you on 5.1?
can you share the gltf file with us?

Tried on 5.1 and 5.2

Exported the LyraStarterGame/Content/Characters/Mannequins/Animations/Manny/MM_Walk_Fwd.uasset
MM_Walk_Fwd.glb (20.4 MB)

As far as I can tell, you cannot roundtrip any Manny animation? Let me know if you find one you can export and then reimport. Maybe I am missing a configuration setting?

On import it says:
LogInterchangeEngine: [Pending] Importing
LogInterchangeEngine: [Pending] Importing
LogInterchangeEngine: Error: [Failure] Import Done
LogInterchangeEngine: Error: [Failure] Import Done

Thanks for your help

  1. Your glb seems to be wrong as it does not import in Khronos gltf viewer.

  2. I managed to export from 5.1 and 5.2 but failed to get skeletal mesh animation in UE. I did not get the error though and those load in gltf viewers.

I will discuss with dev and see what could be the issue, thank you for reporting.

Thanks @UE_FlavienP - the GLB was created just by exporting the stock manny animation.

Would be great if we could export glb mannequin animations from UE!

Noted.

The dev fixed some bad transforms in the export, but we are still investigating the re-import issue in UE.

Bests.

This is still an issue in 5.2.

Choose any animation and export as gltf or glb.

Then try to import that back into unreal.

No animation is created :frowning:

The two tickets I created for the “Manny walk animation”, issue on exported animation and issue on reimport, have been fixed for 5.3. If you build from source you could try.

Awesome! Thank you @UE_FlavienP !!

Cant wait to use GLTF/GLB for more pipeline stuff. :slight_smile:

Let me know if you need a step-by-step repro for the reimport - but it seems to happen with any animation.
