Problems with IK bones with UE4 -> UE5 retargeters provided in 3rd person example

[E_PepeGamer]

I am converting my UE4 animations to the new UE5 skeleton (manny and quinn) using the UE4 UE5 IK retargeter provided with the default 3rd person empty project.

Animations are converted to the new skeleton and look properly, however when showing the ik bones (ik_foot_root, ik_foot_l … , ik_hand etc) these are not at their correct position.

I could attach an example animation or pose, but first I would like to know if anyone else has experienced this issue and how to notify the developers.

I have the same problem. @E_PepeGamer , have you already found a solution?

[E_PepeGamer]

Nope. Also, I think I saw these bones marked as deprecated? I am not really sure about this though.

I had the same issue with IK bones not being properly retargeted/positioned.

To fix the position issue, I used this free plugin to reposition the IK bones, by snapping them to FK bones using a custom solver in the IK Rig asset.

Here’s a post I made today, with additional notes/tips about the IK bones’ retargeting process:

UE5 - IK Retargeter not properly positioning IK bones

Don’t forget to check if the chain mappings for the IK bones are properly mapped in your IK Retargeter asset. Also, check if the retarget chains for the IK bones are actually set up in both the source and target’s IK Rig assets! For some reason, it seems Epic removed the retarget chains for the IK bones, in the default IK_Mannequin IK Rig asset. So, I had to re-add them myself. Additional notes about my retargeting process: I’m using Unreal Engine v5.4.4. In my screenshots, I’m retarge…
