When I export my baked animation as an FBX (to be used in Unity), the IK feet animation doesn’t export but works fine when I play the animation in the original file. I uploaded a comparison of the original and the exported (These are still frames of the animation).
Original
Exported (Ignore the broken UVs. that’s another problem)
Sounds like you need to bake your animation to keyframes before exporting (Google)- also make sure you don’t have any drivers on any bones, as those don’t export. If you do, bake them
The thing is I already baked the animation. I animated it using layers, and then baked them all into a single layer. I also found out that FBX can’t export seam data, so that explains the UVs at least.
