Extrude by colour

  1. It is better to paint on a black surface right away, because that way all color channels are initially set to 0.
  2. After painting you should promote colors to primitives, because this is what primitive extrude is working with.
  3. If however you have chosen to paint red on white, the red channel will be set to 1 everywhere. Red = 1,0,0 and White = 1, 1, 1.
  4. Thats why the green or blue channel is more distinctive here: Set your primitive wrangle to f@r = 1.0 - @Cd.g; so its able to tell where red is being used.
  5. Inside the primitive extrude set 'distance' to something larger than 0 and set 'distance scale' to r.
