"Old" UE4 mannequin control rig not working properly in UE5

[AF01]

Hello The UE4 mannequin Control Rig, migrated from 4.26 to 4.27, and finally to 5, gives up strange results, only on the legs/feet, when you bake an animation to it.

There are no errors, it all works, but gives up these strange results.
If anyone has any idea how to fix this, it would be awesome, and I’m sure usefull to many more people.

Thanks!

I managed to fix it eventually, by deleting the toe/ankle controls, redoing the leg/foot IK and adding a simple FK toe control.

managed to fix this by simply reversing the Left/Right leg ik node order in the Backwards solve event (knee_l_pv_ctrl → foot-L-ctrl → ball-L_ctrl)

Ty! Have to try this!

@Luffarschack @AF01
Thank you guys, this made it work for me as well!
Before I had this issue:

Then I changed the order of the backward solver to this one:

Then the bake worked perfectly fine.
