Hello!

I'm using Blender for my little game development hobby and my content pipeline relies on the X file format.
I get blend files from 3D artist, they are like the one attached.
Animation is based on constraints, so I have to bake bone transformations to get them to X file (see BakingForX.jpg).
And then I export the mesh (ExportDirectX.jpg) by selecting the mesh and the armature.
The problem is that in the exported X file the animation doesn't always match the one we can see in Blender. For example the legs of the dog for some reason get crossed at some frames.
(BlenderPose.jpg and StrangePose.jpg)
And the fall animation twists the spine a lot.
I expect animations to be identical.
Not sure what I can do about it.
Thank you!
