Adding Another Glow
 
 
 

The effects you’ve added to the Sun have included the Glow Behind option, so they are not adding a glow to the planet, which is in front of the light. Now that your Sun is glowing in the sky, you need to add glow to the planet itself.

Add a second glow to your scene:

  1. Select the planet in a viewport. Right-click and choose Properties in the Transform quadrant of the quad menu.
  2. In the Objects Properties dialog > G-Buffer group, change Object Channel to 1 and click OK to close the dialog.

  3. In the Environment and Effects dialog > Lens Effects Parameters rollout, add another Glow to the list of effects.
    NoteIf you closed this dialog you need to select the Sun omni light and click Setup on the Atmospheres & Effects rollout.
  4. In the Glow Element rollout, rename this effect Glow on Planet.
  5. Click the Options tab and in the Image Sources group, turn on Object ID.

    Notice that the number is set to 1 by default.

    The planet now renders with a bright white glow. This is too intense.

  6. Click the Parameters tab. Set Occlusion to 0.0 and turn off Glow Behind.
  7. Change Intensity to 45.0 and Source Color to 50.0.
  8. In the Radial Color section, change the white color swatch to a darker brick red.

    The planet is looking better now.

    TipIf the planet is still shadowy, move the marslight closer to the planet in the Top viewport.

Make global adjustments:

On the Lens Effect Globals rollout, you can make global adjustments to control the whole effect.

  1. Experiment to see what happens when you change Size to 11.0, 22.0, and 33.0.

    As an additional exercise, try animating the effects' settings.

  2. Save the scene as mymarsandsun.max.

Summary

This tutorial has shown how to create Glow, Ring, and Star lens effects, and how to adjust their settings. It also showed how multiple Glow effects can create the effect of ambient lighting, how to create and navigate a camera viewport, and the use of omni lights for scene illumination.
