Description

Utility methods to assist with working with shaders from the Editor.

// Adds a new Editor menu item called Example. Select a shader
// asset in the Project window, then select
// Example > PrintLightModeTagExample from the Editor menu. The value of all
// "LightMode" tags present in any pass of the shader will be printed to
// the console.
