I have rigged a custom character in AccuRIG and used Pose Offsets to fine tune the character rig. When I upload the character to Actor Core and export Motions with the Unreal Engine profile, if I import them in UE5 animations have the original pose instead of the one that I fine tuned with Pose Offsets, and it clips the character body and looks wrong. Everyting looks fine in the Actor Core preview. I'm importing the dowloaded fbx files, one with the Actor and one with the Motion.

Steps:

Modify pose in AccuRIG from default.
Upload character to ActorCore.
Select Motion for custom character.
Download Motion with Unreal Engine profile and zero root motion.
Drag and drop in Unreal content browser with the Actor File.
Drag and drop in Unreal content browser with Motion.
Open the animation in the editor.
You will see the animation with the original pose and no Pose Offsets applied
