Copy Pose/ Retarget Pose Anim BP nodes doesn't copy simulated poses?

Using LeaderPose node works fine, but the skeleton differences prevent the usage of this, as it’s from als to metahuman, so I am using the Retarget Pose from Mesh node in Animb BP.

This was working fine for this project in 5.3, after upgrading to 5.4 the Retarget Pose node is not copying the simulated positions, just the target animation positions.

This issue is happening with both copy pose and retarget pose from mesh, but not set leaderpose node.

Example Bug Video

This video example is using the retarget pose from mesh node, issue also happens with copy pose from mesh.

Any one have any idea what could be triggering this weird behavior? We never experienced it in UE5.3

Seems related to LODs somehow, since cam distance seems to affect it, at a distance you can see the source mesh is ragdolled/simulated on the floor, but the copying mesh just stands there ignoring the physics until you get closer, it’ll snap into ragdolls position…

Not sure where to begin on that, is there such a setting that causes copy pose/ retarget pose to ignore simulated joint positions at higher LODs?




Here’s also some screenshots of the retarget node in animbp and retargeter.
And showcasing the issue, from a distance, simulated joints are ignored when using retarget or copy pose from mesh node.

Edit:: Just a update, its not all meshes, seems to only happen in the als character bp.

But I can’t find any LOD setting related to having simulated joints copied or something similiar.

Edit 2 :: problem solved, removed capsule component from affecting camera trace collision. guess it was messing up the bounds of attached components.
