Hi folks, this is just to document an error that some of you might get when you create the Image Effect Shader in Part 10. If you get an error that says “Cannot open source file UnityCG.cginc”, a potential fix is to remove the #include "UnityCG.cginc" line in the image effect shader, and replacing it with the script found at this link: https://github.com/TwoTailsGames/Unity-Built-in-Shaders/blob/master/CGIncludes/UnityCG.cginc.
I’m not sure why this is happening at the moment. Will post updates below as I discover them.
