The mental ray Light Shader rollout lets you add mental ray shaders to lights. When you render with the mental ray renderer, light shaders can alter or adjust the light's effect.
-
Select a light. >
Modify panel > mental ray Light Shader rollout
To adjust the settings for a light shader, drag the shader's button to an unused Material Editor sample slot. If 3ds Max prompts you to choose Instance or Copy, be sure to choose Instance. (If you edit a copy of the shader, you will have to drag the sample slot back to the shader button on the Light Shader rollout before any changes take effect.)
