I have the same problem, don’t know what to do anymore.
It was building correctly on the same unity version, and then without any reason it’s no more working.
Basic Outline is rendering pink, whil just basic is rendering Ok.
Console in Xcode says:
Shader ‘Toon/Basic Outline’: fallback shader ‘Toon/Basic’ not found
WARNING: Shader Unsupported: ‘Toon/Basic Outline’ - Setting to default shader.
I also added the shader in the graphic setting, in the always included shaders list: no luck.
Your problem looks like its just lost one of the shader files from the Standard Assets folder, but can’t say for sure.
Feels like the new standard shaders have been put in and they don’t care about the old toon shaders? If there was a toon option in standard I’d be well happy.
I’m having the exact same problem as adre here. All of a sudden my toon/lit outline stopped working in build. I think the problem was initiated by adding a Canvas with Screen Space - Camera setting to my scene. However removing the canvas doesn’t solve the problem, so its addition is changing something that it’s removal doesn’t revert.
