Hello! I have just imported this animation (from Mixamo), but it looks all jittery when I play it… Is this something common anyone knows how to solve? It plays perfectly in blender, but has this shake when imported to the engine (see video).
Thanks in advance!
Hello @LeoTMad1 ,
You could try the solution mentioned in this post.
In the FBX export settings, try swapping the primary and secondary bone axes (Primary/Secondary Bone Axis), as this can influence how rotations are interpreted when the animation is imported.
Also, when exporting the animation, try disabling the “Simplify” option or reducing its value (for example, to 0.1). This option optimizes keyframes and, in some cases, may introduce small variations that appear as jitter.
Hope it helps!
Unfortunately I don’t export FBX files from blender, but rather I use this awesome plugin Blend File Importer - Unreal Engine Asset to import .blend files directly to Unreal Engine. I use these settings when importing:
Do you perhaps see something here in these import settings that can be done, or do you think all hope is lost as long as I use .blend importer?
I don’t know much about the topic, but from what I’ve been researching, some animations can present jitter due to the plugin, so it’s possible that’s the issue.
If you have Blender, I’d recommend trying to export the animation as I mentioned before to rule out that possibility. On the other hand, in that post several possible solutions are mentioned that you could try; maybe one of them helps you resolve the jitter.
In my opinion, it could be a problem related to the bones and/or the root but I can’t think of any other solution.
