= SUMMARY =

This article provides a method for controlling a model’s ambient color locally, without the influence of the Atmosphere>Ambience RGB settings. Presently, there are no features available to create this type of effect.

= MORE INFORMATION =

The following procedure offers an effective workaround:


 * 1) Set the Atmosphere>Depth Fading RGB values to 0.0.
 * 2) Set the model’s Material parameters to the desired settings.
 * 3) Define a Light source.
 * 4) Edit the Light source: activate the Selective Light->Include option, edit the Light’s RGB values to the color you want to set for the model’s Ambience.
 * 5) Select the model and associate the model to the Light by choosing Light->Associate, then pick the Light icon, or the Light’s Schematic view representation.
 * 6) Repeat steps 1 through 5, to control other scene models’ local ambient color(s).
 * 7) Preview or render the scene.

Now the model’s ambient color is affected by the light source that the model is associated to, without the influence of the global ambient color.
