I tried some solution found on internet like this "make a duplicate of my bone chain, and completely blow away the parenting relationships within the chain. then I added copy transform constraints on each bone in the duplicate unparented chain to its corresponding bone in the spline ik chain." but still cant get right result

I also tried Bake Action in pose mode but also shows wrong result

System Information
Operating system: WIN10

Blender Version

Broken: 2.80 2.79 2.81

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

1.Open File and Export to FBX with Only Deform Bones
2.Import the FBX

I think this is the same as the bug I recently filed, maybe these should be merged? https://developer.blender.org/T73863 Haven't tried DAE though. I described the fix you tried and why it doesn't generally work.
