While testing my Gargoyle project with Blender 3.2 and Verge3D 4.0, I noticed some problems with the tracking of the eyes. See my former post.
In the Blender 3.01 and Verge3D 3.9 version, I used Damped Track together with Limit Rotation constraints for eye tracking, which worked without any issues. Eye-tracking was smooth and precise.
In 4.0, I switched to using Track To constraint, together with Limit Rotation constraint (with slightly different settings) and now the eye-tracking works well for 4.0.
I don’t know if it was the change in Blender or in Verge3D that caused issues with Damped Track constraints.
I would advise using Track To constraint if you use Blender 3.2 and Verge3D 4.0(.1).
