Tweak color bleed

Color bleeding is a by-product of rendering with global illumination. You can affect color bleed with or without lights in the scene.

To render color bleed with light sources in the scene

1. Make sure Illuminates by Default is turned on for the light source(s). (It is on by default.)
2. Select the object onto which you want to bleed color.
3. Tweak the Diffuse attribute of your object’s shaders if necessary.
4. (Optional) Adjust the Irradiance Color slider to reduce or increase intensity of the color bleed.
5. Render with mental ray for Maya.

To render color bleed with no lights in the scene

1. Turn off Illuminates by Default for the light source(s).
2. Select the object onto which you want to bleed color.
3. In the mental ray section of that object’s Attribute Editor, do any of the following:
   • Adjust the Ambient Color attribute.
   • Add some color to the Incandescence attribute.
4. Render with mental ray for Maya.
