Is there a guide on adding laser and reticle for Oculus Go app in Unity?

Honored Guest
Tried following, but the scene used in it is not part of Oculus Essentials for Unity anymore apparently, besides, some parts of it (like making line renderer a child of CenterEyeAnchor) made little sense.
So far I tried making line renderer a child of TrackedRemote (which is a child of RightHandAnchor) but it resulted in line coming from the center of camera for some reason.

@imperativity I follwed the blog examples and implemented a laser pointer on my oculus go controller using OVR Pointer Visualizer. I want to make the laser pointer end at the point it collides with any collider. I am finding this very challenging. have you attempted a version like that? the OVR Pointer Visualizer uses the Ray datatype which has an infinite length, so I'm not seeing any pre-made solutions in the example files in the documentation or the blog that will help me with a colliding laser raycaster.

this one is pretty robust -

this one is more specific to what you are asking about -

There is a laserPointer.cs script built into crossVR manager, which was very handy after slight modification.  IIRC for most things where it wants a "camera" we put it on the controller of origin for the raycast/"laser."
