Default T-Pose Base Position for UE4 Mannequin?

Hi everyone,

Does anyone know if it’s possible to set the UE4 Mannequin’s base pose from A-Pose to T-Pose? I know you can create a new pose (such as T-Pose) within engine when retargeting animations from one model to another, but that doesn’t change the default base pose from A-Pose.

The reason I’m asking this is because I’m te sting LiveLink and have noticed the following issue. When streaming motion capture data into Unreal Engine to models with a A-Pose default base (such as the UE4 Mannequin), the arms of the model gets all skewed. Streaming to a model with a T-Pose default base plays the animation as it should be. Pictures are below which show what I mean. Anyone else run into this issue or know how to fix it?
