Ue5.0.3 - issue with fbx animation import

Development Character & Animation

I upgraded to UE 5.0.3 and i cannot import fbx animations anymore.
I do everything as usual, and never got problems until 5.0.2

With the 5.0.3 version, i always get this error:

“Animation lenght (value) is not compatible with import frame-rate (value fps) - sub frame (value), animation has to be frame-border aligned.”

It happens all the time with any length, any frame-rate.
It happens by importing animations from Rokoko Studio and Mixamo.

I know probably is a bug from latest version, but i really don’t know what to do!
Is it possibile to downgrade to UE5.0.2???

Thank you

Use the custom range and do min 0 and play with the max

Changing of range did not help me. But Bake of animation with “smart bake” option resolved the problem

I’ve been facing this issue too. Tried all the advice on every similar post.

My last resort is to compile the engine from source and try to fix the bug myself.

I’ll post back here if I succeed.

I did also have this problem - but played around with the ‘set range’ and started with a range of 0 to 5 and then after a few tries found 0 to 140 worked.

I’ve been unable to successfully compile 5.0.2. GenerateProjectFile.bat keeps failing due to outdated .NET, even though I’m on the latest.

To everyone else facing this issue: the problem seems to occur when the ratio between Animation length and import frame-rate results in a non-whole number. Tweaking your range can be helpful in some cases, but often results in critical data loss.

This is not a good solution.

Depending on the length of the animation, there may not be a workable value.

I had this problem. I opened up the animation in Maya, then changed the frame rate in the time slider from 29.98FPS to 30FPS, then re-exported it.

It all depends on the target frame rate of the skeletal mesh and your UE project. If you have other animations for that skeletal mesh, hover over them and check the framerate.

Same thing here. I cannot import animations anymore. I hope this gets fixed soon.

Try “Exported Time”. Under the check mark “import animation”, try choosing exported time vs animated time.
I always used animated time till it didn’t work.
