Hello there, I am using Windows 10, Unity 2018.1.2f1. Also occurred in 2018.1.0b13. Probuilder worked fine until I started it up today and when I clicked on any of the parts, it became like this: This is the error: " Shader error in 'ProBuilder/Standard Vertex Color': syntax error: unexpected token ';' at line 288 (on d3d11) Compiling Vertex program with POINT LIGHTMAP_OFF DIRLIGHTMAP_OFF DYNAMICLIGHTMAP_OFF 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_COLORSPACE_GAMMA UNITY_LIGHT_PROBE_PROXY_VOLUME UNITY_LIGHTMAP_RGBM_ENCODING " Also, if it matters, I have realtime global illumination and baked global illumination both turned off. No fog either. The shader shows up under 'failed to compile'; If I select Probuilders Diffuse Vertex Color, I get back colors but it looks a little less good than the standard vertex colors. I'm sorry, but I have no idea how to recreate the error. Also, I came here from the closed progrid bug report forum, so I thought this was the place to go.
