FBX export of armature using Spline IK looks very wrong
Open, Needs TriagePublic


Blender Version
Broken: 2.79

Short description of error
I'm working on a lasso rig using Spline IK. Things seemed to be going okay until I did a test .fbx export. It seems Blender's having trouble correctly baking the animation due to the Spline IK constraint.

Here's a screen grab of what should be the same action being played back together. On the left is what it should be, on the right is the .fbx export.
As you can see, the export goes crazy.

Attaching the .blend file:

To reproduce the error

  1. Export an .fbx of the original animation.


  1. Bake the action.

Either will show a craziness unlike the original animation.
