changing the 3D model of the ARkit face tracking demo
I was able to get the Unity ARkit face tracking demo working with an iPhone X (screenshot 1) to animate a face model in realtime.
I then tried to get it to work with my own 3D model, and imported the FBX file with the same blendshapes (though each blendshape has a different name from the original sloth model, screenshots 2 & 3). By using the hierarchy, ARFaceAnchorManager, and changing the Anchor Prefab I was able to select the model to use.
The problem is:
- the rendered model is flipped around the z axis (it faces away from the camera - screenshot 4). I've tried to apply a 180 degree rotation to the model in Unity's transform window, but it doesn't seem to do anything.
- I'm unsure how to map the blendshapes coming from the iPhone app to the blendshapes in the FBX model - where is that done? Couldn't find any code for it.
