look left not working

[branaway]

const lookleft = this.vrm.expressionManager.getExpressionTrackName( THREE_VRM.VRMExpressionPresetName.LookLeft );

It would return null.

The model is a custom made by an external artist if it's relevant.

three-arm 1.0.6 with threejs 146

it would return undefined t be precise.

I'm working with something similar. In fact, I have issues setting the look left, look right, surprised, lookup, look down while other expressions are just working fine.

I cannot rule out the possibility that the model from VRoid studio is faulty thou.

Moving to Discussions since it's an avatar specific issue

VRoid Studio models doesn't have Look expressions, since the eye movement is manipulated by bones instead.
You would want to use LookAt API instead.

See the lookat.html example in three-vrm:
https://github.com/pixiv/three-vrm/blob/v1.0.6/packages/three-vrm/examples/lookat.html

What about surprised expression then?

[0b5vr]

What do you mean?

Eye controls are LookAt's duty, facial expressions are Expression's duty.

Surprised and Neutral don't work too
