Vertical Plane Detection help.

Hey!

I have this script that uses a placement tracker for arfoundation markerless AR.

When the screen is clicked it places a gameobject on the plane it has detected.

I now need it to work for vertical plane detection although if someone has another way, id be happy to use that too.

Im new at all this, so looking at it, its not obvious for me what to change. The only thing i tried was changing the var cameraBearing = new Vector3(cameraForward.x, cameraForward.y, 0).normalized;

and sticking a zero into one of the other axis, but to no avail.

Any help work be much appreciated.

Cheers
