- A custom visual shader graph expression written in Godot Shading Language.
- Description
- -----------
- Custom Godot Shading Language expression, with a custom amount of input and output ports.
- The provided code is directly injected into the graph's matching shader function (``vertex``, ``fragment``, or ``light``), so it cannot be used to declare functions, varyings, uniforms, or global constants. See :ref:`VisualShaderNodeGlobalExpression<class_VisualShaderNodeGlobalExpression>` for such global definitions.

- An expression in Godot Shading Language, which will be injected at the start of the graph's matching shader function (``vertex``, ``fragment``, or ``light``), and thus cannot be used to declare functions, varyings, uniforms, or global constants.
