Shader Fails on Some Platforms

[owlboy]

I have successfully used these shaders on my Mac with Unity using OpenGL 3.3 in the past.

The newest release turns magenta, and shows this single error in the console:

Shader error in 'CubedParadox/Flat Lit Toon': invalid subscript '_ShadowCoord' at line 62 (on glcore)

Compiling Vertex program with DIRECTIONAL SHADOWS_SHADOWMASK TINTED_OUTLINE Platform defines: UNITY_ENABLE_REFLECTION_BUFFERS UNITY_USE_DITHER_MASK_FOR_ALPHABLENDED_SHADOWS UNITY_PBS_USE_BRDF1 UNITY_SPECCUBE_BOX_PROJECTION UNITY_SPECCUBE_BLENDING UNITY_ENABLE_DETAIL_NORMALMAP SHADER_API_DESKTOP UNITY_LIGHT_PROBE_PROXY_VOLUME

The shader works as expected when uploaded to VRC. I just don't get a preview.

If this is unavoidable, is there a fallback option for this environment? 😅 I currently won't be able to easily make preview images for VRC on this machine. If it fell back to standard that would be useful.

Current version of the issue (I may have submitted an incomplete log last time):

Same issues on my Mac running in Unity 5.6 and in 2017
