another way of stating it
Nutcracker ALWAYS creates rgb effects, even if your entire show is single color props.
Our effect generations have 24bit RGB color values.
The way Matt solved how do you have multi color effects and single color props?
Create a prop using single color red, single color blue, single color green or single color white. And have that prop respond only to its channel.
Suppose you have a bars effect with red
you have 4 mini trees, single color Red, Green,Blue, White
if you put the bars effect on all 4:
1) The Red tree responds to any value in the red channel. So this will light up when the red bar goes by
2) The Green tree responds to any value in the green channel. So nothing lights up
3) The Blue tree responds to any value in the blue channel. So nothing lights up
5) The white tree responds to any time that RGB all equal each other. it will only light up with a
value like 50,50,50, 120,120,120, 255,255,255 . So since we have red (255,0,0) , it doesnt light up.
If you have 50,50,51 then that is not a pure white (or gray) color and the white tree would not respond to those.
BTW, if you turn on sprakle or have any white color, your Red, Green and Blue trees will respond. they have a channel matching the RGB they watch.
