Editing AudioLink Setup (section)

=== Step 5: Choose a Mapping Method ===
By default, the colour of your emission map (including any alpha transparency) will be multiplied by the AudioLink band colours that are selected for each of the 4 audio bands (ie. Bass, Low-Mid, High-Mid, and Treble):

Using these default settings, AudioLink will glow blue for bass notes, red for low-mid notes, and green for high-mid notes.

This default mapping method works well if your emission map is white, and it also supports alpha transparency. However, if your emission map is something other than white then it will act as a colour filter. That means that the AudioLink colours will not be visible if they don't match the colour of your emission map closely enough.

Fortunately, there are 5 other mapping options that allow you to map the AudioLink band colours directly to the RGBA channels of your emission map:

The bottom 4 options allow you to select just one of your emission map's colour channels (ie. RGBA) to control the strength of all the AudioLink colours directly. That means they won't apply any colour filtering, nor will they apply alpha transparency.

Choosing "'''Map Band Colours to RGBA Channels'''" is the most advanced option, and will map the AudioLink band colours to each RGBA channel in your emission map, as follows:
