ShaderMaterial
==============

**Inherits:** :ref:`Material<class_Material>` **<** :ref:`Resource<class_Resource>` **<** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`

A material that uses a custom :ref:`Shader<class_Shader>` program.

.. rst-class:: classref-introduction-group

Description
-----------

A material that uses a custom :ref:`Shader<class_Shader>` program to render either items to screen or process particles. You can create multiple materials for the same shader but configure different values for the uniforms defined in the shader.

\ **Note:** Due to a renderer limitation, emissive **ShaderMaterial**\ s cannot emit light when used in a :ref:`GIProbe<class_GIProbe>`. Only emissive :ref:`SpatialMaterial<class_SpatialMaterial>`\ s can emit light in a :ref:`GIProbe<class_GIProbe>`.

.. rst-class:: classref-property

:ref:`Shader<class_Shader>` **shader**

.. rst-class:: classref-property-setget

- void **set_shader** **(** :ref:`Shader<class_Shader>` value **)**
- :ref:`Shader<class_Shader>` **get_shader** **(** **)**

Method Descriptions
-------------------

.. _class_ShaderMaterial_method_get_shader_param:

.. rst-class:: classref-method

:ref:`Variant<class_Variant>` **get_shader_param** **(** :ref:`String<class_String>` param **)** |const|

Returns the current value set for this material of a uniform in the shader.

.. rst-class:: classref-item-separator

----

.. _class_ShaderMaterial_method_property_can_revert:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **property_can_revert** **(** :ref:`String<class_String>` name **)**

Returns ``true`` if the property identified by ``name`` can be reverted to a default value.

.. rst-class:: classref-item-separator

----

.. _class_ShaderMaterial_method_property_get_revert:

.. rst-class:: classref-method

:ref:`Variant<class_Variant>` **property_get_revert** **(** :ref:`String<class_String>` name **)**

Returns the default value of the material property with given ``name``.

.. rst-class:: classref-item-separator

----

.. _class_ShaderMaterial_method_set_shader_param:

.. rst-class:: classref-method

void **set_shader_param** **(** :ref:`String<class_String>` param, :ref:`Variant<class_Variant>` value **)**

Changes the value set for this material of a uniform in the shader.

\ **Note:** ``param`` must match the name of the uniform in the code exactly.
