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.
