=== Decal Positioning / Sizing ===
The decal UV coordinates specify the centre of the decal. The centre of the decal remains fixed when rotation and scaling are applied.

Although the decal's position can be set manually, it is much easier to zoom-in to where you want the decal to be, then click the "Click here to set decal position" button. Note that this uses Unity's raycasting, which does not always work reliably (I'm not sure why). If it does not work, move or rotate the camera slightly and try again.

If tiling is on, the decal will repeat. Otherwise it will only appear in one location.

=== Decal Albedo ===
The decal will be applied as though it is part of the fur's albedo colour.

=== Decal Emission ===
The decal will give off its own light.

Note that if you intend the decal to only light up when AudioLink is active, you should leave this off.

=== Decal Hue Shift ===
Allows the decal map's colour to be "rotated", so that Red -> Green -> Blue -> Red.

If the "Decal Hue Shift Cycling" is set to use an AudioLink channel, then the hue will shift whenever the matching AudioLink band is active, with stronger sounds rotating faster. When the sound stops, the rotation will stop, and it will remain on the colour it has stopped at until another matching sound plays.

=== AudioLink Reactive ===
When an AudioLink band is active, the decal will give off additional emission. This can be applied as static layers, dynamic layers, or both.

Each of the 4 AudioLink bands can be assigned to light up with its own colour, which will be multiplied by the decal's colour. Typically this means you would want to use white decals for AudioLink effects, so that the actual colour can then be determined by the AudioLink band colour.

In the screen grab above, I have configured a heart decal on my chest to light up the dynamic layers in red whenever a bass note plays.

=== Luma Glow ===
Luma Glow allows a world to broadcast colour data directly, rather than as a reaction to music.

"Zones" will be applied as a consistent emission colour along the entire length of the hairs, using the AudioLink static layer skin, root, middle, and tips strength settings.

"Gradients" will be applied as a gradient of emission colours, changing along the length of the hairs.

The differences between the various zones and gradients is determined by the world's authour.
