Setting up the UE4 Mannequin for Rokoko Studio
Setting up the character
You can set up the SK_Mannequin skeletal mesh as you would with any other character. Just follow the Rokoko Studio Live Plugin for Unreal Engine guide: https://github.com/Rokoko/rokoko-studio-live-unreal-engine/wiki/Rokoko-Studio-Live-Plugin-for-Unreal-Engine
Here is a cheatsheet for the Bone Map Data Asset:
Setting the character from A-Pose to T-pose
Start by navigating to the SK_Mannequin and opening the skeleton. Now pose the character in a T-pose.
Create a PoseAsset and choose Current Pose.
Now open the Animation blueprint you have created and drag in the PoseAsset. Right-click the pose asset in the Animation blueprint and convert to pose by name.
Set the pose name to the same as the name of the pose inside the PoseAsset and set the pose weight to 1. Now connect it to the Rokoko Body Pose
Now when you click play it should have fixed the pose.
