NONDIFFUSE

THE BOX'S MAIN HELP:

This box adds the __nondiffuse flag to a light shader's parameter list.
If the FLAG is set to 1, the light will be ignored by the 
diffuse function of any material interacting with this light.
Please refer to the RenderMan Shading Language Extensions.

FLAG (input):

This is a flag, an integer, which must either 1 or 0, on or off.
If the FLAG is set to 1, the light will be ignored by the 
diffuse function of any material interacting with this light.
Please refer to the RenderMan Shading Language Extensions.
