glTF animation import faulty - hundreds of sequences - why?

Hi there,

I have been testing out the first animation exports in blender as glTF. On import into unreal engine 5.3 I get hundreds of animation sequences with 1 second. The full animation is there as well as shown in the picture provided.

What export setting or import setting do I need to tweak to only have the full animations imported?

Best wishes!

Have you tried on a newer version of the engine?
Could you share the glTF file with me in DM?

Hi there,

I can not, but I have the same issue like this person had a while ago in another thread (link at end of this post). There was no update on this unfortunately and im trying to figure out how I can prevent having 600 animation sequences created on import. You can also see a provided file to reproduce the issue I have.

Any help greatly appreciated!

Apparently it is because there is a mix of nodes that are joint and not joints in the hierarchy. At least that was the case for the robot sample from the other thread.
Support for this edge case was added in 5.6.

Alright, well I will investigate that in detail then in the future. At least the animation is “somewhere” between those hundreds of sequences. When I find something, ill post it here.
