VisualShader
============
**Inherits:** :ref:`Shader<class_Shader>` **<** :ref:`Resource<class_Resource>` **<** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`
A custom shader program with a visual editor.
Description
-----------
This class allows you to define a custom shader program that can be used for various materials to render objects.
The visual shader editor creates the shader.
