Detailed Description

struct Meta_SurfaceShaderDefinition;

A SurfaceShaderDefinition represents a shader object, expected to be used by a Meta_SurfaceShaderInstance.

The inputs to the shader will be set by this nodes Meta_MaterialParameter children.

Expected Implementation Details:-

When the SourceCode property changes a search for <params> defined within it is initiated, which in turn will extract the expected inputs for the shader. Meta_MaterialParameter nodes corresponding to these parameters will be created as children of the Meta_SurfaceShaderDefinition with their defined default values, allowing the user to easily configure the shader from the property panel or a script. If these #pragma's are missing in the source the user will have to manually create the child Meta_MaterialParameter nodes and set their values.
