RGBW question

[aERonAUtical96]

Still have a few A/C lights.  The elements I have contain 4 colors.  In the past I've done 2 things.  Either create 4 models, 1 for each color, or 2 models, 1 RGB and 1 White.  I've never been able to get a single model setup as a 4 channel RGBW since when I turned on White, all the lights came on.

In the string properties, there is RGBW Color Handling option with 3 entries in the Drop down.
R=G=B -> W
RGB Only
White Only

Can someone explain or point me to documentation on the behavior of these 3 options?

RGB Only will ignore the white channel entirely.  If you set a white effect on it, the R, G, and B channels will lite up.

White only will only light up white channel (if r=g=b) and not any other channels.   The two of those allow "shadow" models to work fairly well.  Create one for the RGB and another for the W and drop effects where needed.

The R=G=B -> W  is the normal operation.   You can drop any color onto the model and if the three channels are equal, it will light up the W channel instead.
