Vision

For items that can accept vision modifications (like helmets and ballistic masks) but don't have a rating, treat as Rating 2 instead.

For Imaging Scopes and natural senses not granted via awakening, treat as if Rating 6.

Apply Vision

let rating = origin.system.technology.rating; /* For most technological sources. */
let rating = actor.system.attributes.magic.value; /* For adept and critter powers. */
let rating = 6; /* You can also set a static value, for natural senses or special cases. */

Combine one of the above with one of the below. Change the angle to 30 for handheld items (scopes, cameras, etc).

Thermographic Vision

token.document.update({
	sight: {
		color: "#CC6600",
    	range: (rating / 2 + 1) ** 2, 
    	angle: 360
	}
});

Low-Light Vision

token.document.update({
	sight: {
		color: "#002244",
    	range: (rating / 2 + 2) ** 2, 
    	angle: 360
	}
});

Remove Vision

token.document.update({
	sight: {
    	color: null,
        range: 0,
        angle: 360 /* Always reset back to 360. */
	}
});
