Global Illumination

This scene is created using Maya Software. Rendered using After Effects Software.


Primitive shapes are used to create a simple scene.
I have disabled default lighting and used Mental Ray to render the scene.
Spot Light is used as the main source of light for the scene.
Exponent value in the attributes can be used to control Photon value.

  • All the diffuse lighting in a scene until the light decays.
  • Indirect lighting method uses photons.
  • Spotlight is best suitable for firing photons.
  • Photon color, intensity and exponent.
  • Photons can be computed and saved in the project for future use.
  • A photon map can be generated to view photons in the viewport.
  • Color bleeding can be observed.
  • Accuracy, scale, radius and merge distance.
  • Sometimes GI must be combined with other lighting method to improve the quantity of render.
