Proximity 📏
Proximity allows us to hide the hologram if a user is too far away (or, optionally, too close). This is useful because it can free up resources for people not actively looking at the hologram effect, and I suggest leaving the values relatively low (for example, start fading between 10 and 20).
Far Away Proximity
This hides the hologram for users too far away, with a smooth fade-out transition effect. Start is when the hologram is still visible, but starts to fade away, and End is when it is completely invisible and doesn't render for anybody.
Close Proximity
This hides the hologram when people get too close to it (for instance, right in front of it). The Start and End operate on the same principle as the Far Away Proximity. This is off by default and doesn't provide many performance benefits, but may be useful for stylised choices.
