Overview
The Positional Anchor resource attaches an anchor to an object in the scene. Anchors represent a position in the scene. This anchor can be used by other resources, such as the Screen Message and Move User resources.
The author is also able to specify an anchor to which this Positional Anchor is attached to.
If an anchor/scene object is specified, the Positional Anchor's position will be relative to the anchor's origin/pivot point. Otherwise, the anchor will be relative to the scene's point of origin.

Creating a Positional Anchor
If you don’t use the VR Editor to create a custom Positional Anchor, you can manually enter in location values. Follow these instructions to create a Positional Anchor.
Adding a Positional Anchor from Catalog to a Script
Let's say I want to add a video at a certain point in the scene in a particular location. I'll use the positional anchor to place the video exactly where I want. I've previously used the VR Editor to create a custom location, instead of manually adding a fixed or relative position.
Open the appropriate script and go to the area where your scene objects are
Use the Catalog icon on the far right to find the positional anchor
Drag and drop the anchor to the Resources pane of the script and save
Open the frame where you want to put the Resource.
Add the appropriate resource for the content (in this example I’ve added a Screen Media Resource to show a video)
Select your custom anchor from the dropdown:
Test in the headset. The Resource should appear at the location of the Positional Anchor:
