	<brief_description>
		A base type for the parameters within the visual shader graph.
	</brief_description>
	<description>
		A parameter represents a variable in the shader which is set externally, i.e. from the [ShaderMaterial]. Parameters are exposed as properties in the [ShaderMaterial] and can be assigned from the Inspector or from a script.

	<members>
		<member name="instance_index" type="int" setter="set_instance_index" getter="get_instance_index" default="0">
			The index within 0-15 range, which is used to avoid clashes when shader used on multiple materials.
		</member>
		<member name="parameter_name" type="String" setter="set_parameter_name" getter="get_parameter_name" default="&quot;&quot;">
			Name of the parameter, by which it can be accessed through the [ShaderMaterial] properties.
		</member>
		<member name="qualifier" type="int" setter="set_qualifier" getter="get_qualifier" enum="VisualShaderNodeParameter.Qualifier" default="0">
			Defines the scope of the parameter.

	<constants>
		<constant name="QUAL_NONE" value="0" enum="Qualifier">
			The parameter will be tied to the [ShaderMaterial] using this shader.
		</constant>
		<constant name="QUAL_GLOBAL" value="1" enum="Qualifier">
			The parameter will use a global value, defined in Project Settings.
		</constant>
		<constant name="QUAL_INSTANCE" value="2" enum="Qualifier">
			The parameter will be tied to the node with attached [ShaderMaterial] using this shader.
		</constant>
		<constant name="QUAL_INSTANCE_INDEX" value="3" enum="Qualifier">
			The parameter will be tied to the node with attached [ShaderMaterial] using this shader. Enables setting a [member instance_index] property.
