Xen Custom Shader Parameter: Fixed Color Distribution

[martinmichl]

Hello I would like to create cables with Xgen and I am stuck getting the color right. I am looking of a solution to distribute 4 predefined colors to a description. that means I would like blue,red and yellow to be randomly distributed amongst them. it should not be color varieties nor random colors. help would be much aprechiated thnx Martin

$blu = [0,0,1]; #color

$yel = [1,1,0]; #color

$red = [1,0,0]; #color

$rand=rand(0,3);

wchoose($rand, $red,0.33, $yel, 0.33, $blu,0.33)

The  values after each variable, 0.33, control the weighting of the choice, so you could bias Blue over the other two by increasing it's weight (The weight has to normalize to 1)
