LookAt blendshapes

[James-messant]

Is it possible to control eye movement through blendshapes using this arkit model:
https://github.com/hinzka/52blendshapes-for-VRoid-face?

currentVrm.expressionManager.setValue("EyeLookOutLeft", 0.6);
This line does not work for me even though the model contains an expressionVrm blendshape for it.

I've tried doing : lookAtTarget.position.y = eyeLookUpLeft - eyeLookDownLeft
Which works somewhat okay but was wondering if there was a better way of doing it.

There are two types of LookAt in VRM: models that use Expression(BlendShape) and models that use Bone.

If you want to support both, use VRM.LookAt.
