light_shaders

#Overview Each light object in the scene has a Light Shader applied to it. This shader is responsible for determining how the lamp functions. A number of the shader functions are set by the selections made in the lamp object data tab (such as the lamp type, size and cone angles), however, there are a number of useful settings that are handled within the node itself.
Please note the settings in the light object data will override the settings in the light shader node if they do not match up. For instance using a PxrStdAreaLight node with a light that is set to Sky in the object data will result in a sky lamp for the scene, not an area light.

##Light shader types

• PxrStsAreaLight: This light shader is valid whenever the Area, Spot, Distant, or Point lamp is selected.
• PxrStdEnvDayLight: This light shader is valid whenever the Sky lamp is selected.
• PxrStdEnvMapLight: This light shader is valid whenever the Environment Light lamp is selected.

##Shader options Please refer to the Renderman documentation for more information on the shader settings and what they do.
