CanvasTexture
=============
**Inherits:** :ref:`Texture2D<class_Texture2D>` **<** :ref:`Texture<class_Texture>` **<** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`
Texture with optional normal and specular maps for use in 2D rendering.
.. rst-class:: classref-introduction-group
Description
-----------
**CanvasTexture** is an alternative to :ref:`ImageTexture<class_ImageTexture>` for 2D rendering. It allows using normal maps and specular maps in any node that inherits from :ref:`CanvasItem<class_CanvasItem>`. **CanvasTexture** also allows overriding the texture's filter and repeat mode independently of the node's properties (or the project settings).
\ **Note:** **CanvasTexture** cannot be used in 3D rendering. For physically-based materials in 3D, use :ref:`BaseMaterial3D<class_BaseMaterial3D>` instead.

.. _class_CanvasTexture_property_diffuse_texture:
.. rst-class:: classref-property
:ref:`Texture2D<class_Texture2D>` **diffuse_texture**
.. rst-class:: classref-property-setget
- void **set_diffuse_texture** **(** :ref:`Texture2D<class_Texture2D>` value **)**
- :ref:`Texture2D<class_Texture2D>` **get_diffuse_texture** **(** **)**
The diffuse (color) texture to use. This is the main texture you want to set in most cases.
.. rst-class:: classref-item-separator
----
.. _class_CanvasTexture_property_normal_texture:
.. rst-class:: classref-property
:ref:`Texture2D<class_Texture2D>` **normal_texture**
.. rst-class:: classref-property-setget
- void **set_normal_texture** **(** :ref:`Texture2D<class_Texture2D>` value **)**
- :ref:`Texture2D<class_Texture2D>` **get_normal_texture** **(** **)**
The normal map texture to use. Only has a visible effect if :ref:`Light2D<class_Light2D>`\ s are affecting this **CanvasTexture**.
\ **Note:** Godot expects the normal map to use X+, Y+, and Z+ coordinates. See `this page <http://wiki.polycount.com/wiki/Normal_Map_Technical_Details#Common_Swizzle_Coordinates>`__ for a comparison of normal map coordinates expected by popular engines.

.. _class_CanvasTexture_property_specular_color:
.. rst-class:: classref-property
:ref:`Color<class_Color>` **specular_color** = ``Color(1, 1, 1, 1)``
.. rst-class:: classref-property-setget
- void **set_specular_color** **(** :ref:`Color<class_Color>` value **)**
- :ref:`Color<class_Color>` **get_specular_color** **(** **)**
The multiplier for specular reflection colors. The :ref:`Light2D<class_Light2D>`'s color is also taken into account when determining the reflection color. Only has a visible effect if :ref:`Light2D<class_Light2D>`\ s are affecting this **CanvasTexture**.
.. rst-class:: classref-item-separator
----
.. _class_CanvasTexture_property_specular_shininess:
.. rst-class:: classref-property
:ref:`float<class_float>` **specular_shininess** = ``1.0``
.. rst-class:: classref-property-setget
- void **set_specular_shininess** **(** :ref:`float<class_float>` value **)**
- :ref:`float<class_float>` **get_specular_shininess** **(** **)**
The specular exponent for :ref:`Light2D<class_Light2D>` specular reflections. Higher values result in a more glossy/"wet" look, with reflections becoming more localized and less visible overall. The default value of ``1.0`` disables specular reflections entirely. Only has a visible effect if :ref:`Light2D<class_Light2D>`\ s are affecting this **CanvasTexture**.

.. _class_CanvasTexture_property_specular_texture:
.. rst-class:: classref-property
:ref:`Texture2D<class_Texture2D>` **specular_texture**
.. rst-class:: classref-property-setget
- void **set_specular_texture** **(** :ref:`Texture2D<class_Texture2D>` value **)**
- :ref:`Texture2D<class_Texture2D>` **get_specular_texture** **(** **)**
The specular map to use for :ref:`Light2D<class_Light2D>` specular reflections. This should be a grayscale or colored texture, with brighter areas resulting in a higher :ref:`specular_shininess<class_CanvasTexture_property_specular_shininess>` value. Using a colored :ref:`specular_texture<class_CanvasTexture_property_specular_texture>` allows controlling specular shininess on a per-channel basis. Only has a visible effect if :ref:`Light2D<class_Light2D>`\ s are affecting this **CanvasTexture**.

----
.. _class_CanvasTexture_property_texture_filter:
.. rst-class:: classref-property

- void **set_texture_filter** **(** :ref:`TextureFilter<enum_CanvasItem_TextureFilter>` value **)**
- :ref:`TextureFilter<enum_CanvasItem_TextureFilter>` **get_texture_filter** **(** **)**
The texture filtering mode to use when drawing this **CanvasTexture**.
.. rst-class:: classref-item-separator
----
.. _class_CanvasTexture_property_texture_repeat:
.. rst-class:: classref-property
:ref:`TextureRepeat<enum_CanvasItem_TextureRepeat>` **texture_repeat** = ``0``

- void **set_texture_repeat** **(** :ref:`TextureRepeat<enum_CanvasItem_TextureRepeat>` value **)**
- :ref:`TextureRepeat<enum_CanvasItem_TextureRepeat>` **get_texture_repeat** **(** **)**
The texture repeat mode to use when drawing this **CanvasTexture**.
