## Introduction

Light shaders are able to set some of the properties of Redshift Lights. For this their *Light Color Shadow Amount* output has to be connected to the *Light* Input port of a Redshift *Output* node. Finally this node material has to be assigned to a matching Redshift Light object. Although it is possible to apply, for example, a *Dome Light* shader to any other type of *Redshift Light* object, only applying a *Light* shader to a matching type of *Redshift Light* guarantees that all the shader's settings can be applied to the light object.

Only the *Physical Light* shader can be applied to any type of *Redshift Light* as it only sets standard light parameters, such as the *Color* of the light, the *Decay* or the *Shadow* options.

All settings of the *Light* shaders are identical to parameters found at the *Redshift Light* objects. The only exception is a **Gobal On** option, to switch the light emission on or off directly from within shader.

The fastest way to use a matching *Light* Shader with an existing *Redshift Light* is by using the *Add Graph* button in the dialog of the Light object.

The new material is automatically applied to the light source and controls some of its settings from now on. Because of this, some parts of the Light Object dialog will appear grayed out, but you can still edit these parameters by opening the new *Light Shader* group on the Object tab of the *Redshift Light* object dialog.

Using the *Add Graph* button will always create a *Redshift Shader Graph* material, that can be edited or removed directly from within the light objects dialog by using the **Remove Shader Graph** and **Edit Graph** buttons.

## Available shaders

The available *Light* shaders match the Redshift light types for *Dome Lights*, *IES Lights*, *Portal Lights* and the *Sun Lights*. All other light types are covered by the *Physical Light* shader. For more information about how to create and to apply light shaders to light objects, please have a look at the Introduction part on this page.

For an in depth description of the *Redshift Lights* and their parameters, please refer to the description of [Lights](https://help.maxon.net/r3d/maya/en-us/Content/html/Lights.html.md) in this documentation.
