unreal engine 5 skips some bone animation keyframes(FBX file exported from Blender)

i’m not good at English, so i use translator.

when i import an FBX file from blender 4.1 into unreal engine 5, some bone animation keyframes are skipped, i import the same file through another 3D tool(MAYA), it works correctly.
i tried many methods, but still couldn’t fix the issue.

Hello there @anteaterxxxxxx!

Unreal and Blender don’t have the best relation, and animation import is a regular point of conflict. If Maya is giving you good results, I would stick with it.

On the other hand, if you need Blender to work by all means, the first approach is to reset import/export settings on both programs, then test exporting again.

If the issue persists, I would suggest trying the following addon for Blender, which eases the transfer process, and gives you a bit more of control over it. Please check the link below:
