Shader Control is a powerful editor extension that gives you full control of shader compilation and keywords usage and their impact in your game.
*** Features ***

• ‘Project View’: convenient unified view for all shaders with source code in your project.
• List shaders and materials in your project using keywords along shader variant count.
• Quickly locate or open any shader in your project.
• Disable/enable any number of keywords per shader with a click. Shader Control can modify the existing shader automatically for you!

• Removes materials references to disabled keywords at project level.
