' This example demonstrates how to get the user to select a shader and use it to create

' a complex shader with intermediate Mix 2 Colors shaders

' Create a sphere and apply a default shader to instantiate a local material.

' The Render Tree shows a Phong shader connected to the sphere material.

' Pop up a menu of shader presets on top of the Top viewport

' and let the user interactively select one.

' The user-selected shader, automatically renamed Shader, is connected

' to the Phong shader Diffuse and Specular connection points through

' intermediate Mix 2 Colors shaders as can be seen in the Render Tree.
