Using layer-map RGB channels to alter multiple properties independently (PB only)


    In both the Persistent or Ephemeral Property Mappers, you can control up to three particle properties independently by using a single RGB image as a layer map. Particle Playground achieves this by extracting brightness values separately from the red, green, and blue channels in the image. The Persistent and Ephemeral Property Mapper options map the red, green, and blue channels to different properties through the individual color map menus: Map Red To, Map Green To, and Map Blue To. You don't have to use all three channels if you want to modify just one property. To change just one property or change up to three properties using the same values, use a grayscale image as the layer map, because the RGB channels are identical. For more information, see Creating an RGB layer map (PB only).

    Illustration with these callouts: A. Layer map viewed in RGB mode. B. The red channel contains a spiral layer. C. The green channel contains a horizontal-gradient layer map. D. The blue channel contains a vertical-gradient layer map.
