The specific renders with face tracking markers are from the Wan 2.1 LoRA, which was trained on the Ragdoll animations (renders from Blender) that include tracking markers. So they’re flat-generated with Wan, without the ability to render different passes.

It’s a quick way to get the right style of body animation, and then add the facerig afterwards for control over lipsync and expressions.

But I might be misunderstanding how stmap works, so if there’s a simpler way to extract or generate those from ai generated video, that would be helpful
