Hello everyone. Has anyone encountered a similar problem? In preview everything is good, but exported animation is deformed
Hello there @TurboDestruction!
That looks like a retarget mismatch. Just to retrace your steps, I assume you have already applied “Retarget Animations” to all your old assets, and transfer between the two types of skeletetons, as seen in the short guide below:
What the video doesn’t show, is that both skeletal meshes should be side by side, and animating in sync. And an incorrect pose could be causing the problem you are facing.
For that, checking around the community, other users have worked out this problem using a IK Retargeter, to properly pose the target mesh. Please test the following steps:
-
First, create the IK Retargeter via right-click → Animation → IK Retargeter, and set it like this:
- Source = UE4 skeleton
- Target = UE5 skeleton
-
Next, match the poses, save the base pose from the source, then create a new pose for the target, and adjust it to match the original pose. Check all your bones, as well.
-
Now, you can load a UE4 in the Retargeter, and if it still looks off, tweak the target pose until its aligned. Once that’s set, you can Export Animations to a new folder.
This is exactly what I did to get results on my screenshots. I tried to do same process at UE 5.4 and got perfect results where preview = export. Looks like Epic’s break something …again.
UPD: And looks like problem only in exporting stage:

I’m having the same problem. It looks fine in the preview but it’s broken after retargeting. I’m seeing the same warnings/errors in my output log too. As you can see in the screenshot it says “IK Retargeter bone chain, root, was unable to be normalized. Chain too short.” but I’m not sure if that’s causing the issues.

@micahpharoh Do not let the Root chain on top of your IK’s chain list. That’s all
