IK retargeter exported animation breaks #356

I am trying to export animations from IK retargeter in UE 5.3.2. The animations seems to be working fine in the IK retargeter preview.

But when i export the animation out, its hands and related bones are scaled abnormally.

I tried to replicate this issue in 5.2.1, but there the animations from IK retargeter gets exported properly without any deformation. I also tried to migrate these correct animations from UE 5.2.1 to UE 5.3.2. But it doesn't seem to export the VRM related assets there like the materials, asset list , skeleton etc. They are just not getting migrated. I also tried the copy paste method in 5.3.2, and it didn't work either.

VRM4U Plugin versions i have used ( 5_2_20240212, 5_3_20240212 )

If anyone can help with this issue it would be nice.

UnrealEngine Version: UE 5.3.2

Hi. Check the TranslationRetargeting section of Skeleton. If you set it to Skeleton, only the rotation angle of the animation will be applied. When imported by VRM4U, it should automatically be set to Skeleton.

Thanks for the reply. I have tried to change the retargeting options for both the skeleton in my project which are being used in IK retargeter. But sadly it didn't resolve the issue.
