IK Retargeter is not retargeting IK bone information

[Naivrat]

The IK Bone constraints are broken (or I’m just stupid ) I had similar question, and finally I have found how to fix this:

Are offsets supported within the IK Retarget?

Answering my own question: I was right about feet bone position difference (UE4 & UE5 mannequins), but I didn’t realize, that while UE5 mannequins feet are getting snapped to a position where UE4 mannequins feet bones are, the root bone remains in the same position. The exported animation skeleton will look like this: [image] So this is what is actually causing problems like floating feet, because the skeletal mesh origin/pivot is where the root bone is. And the static offset is the way to so…

Constraining bones is covered in this video, #9.0 Constraint Bones - UE5 Manny Integration - ALS Secrets

Look at the video in my answer, it has much easier solution to get the IK bones work.
