For this tutorial I will explain the simplest use case using A single PC for both VR rendering and rendering the UE scene.
The APS live link plugin can be used in configurations ranging from using only a single PC for both VR rendering and rendering the UE scene, to advanced setups using separate PCs for VR tracking/rendering and a separate dedicated tower for UE rendering.

The APS live link plugin requires the vr avatar skeleton used in APS be the same as the skeleton used in the Unreal scene. Building custom avatars is pretty simple, but for this tutorial I am using the prebuilt UE mannequin standard skeleton avatar available on the workshop.

After download a mocap avatar navigate to the Avatars tab, search for "Mannequin" and select the new avatar to activate it.
New sliders have just been added to the arm IK solver profile for limiting the (negative) rotation of the clavicle bone. These were added to address a issue when using Metahuman avatars over live-link, but may be generally useful for other avatars as well!
The new Shoulder Low Limit slider can be used to clamp the clavicle bone rotation so they do not rotate below a set angle.
The new Shoulder Pos Offset slider adds positive rotation offset to the clavicle bone.
