Hey,
I get the following errors with Unity 6.3 Alpha on an M4 Macbook Air. Tried a few commits back with same issue too.
Library/PackageCache/com.chisel@1c63caf53478/Core/2.Processing/Jobs/GenerateSurfaceTrianglesJob.cs(142,17): error CS1739: The best overload for 'Args' does not have a parameter named 'concentricShellsParameter'
Library/PackageCache/com.chisel@1c63caf53478/Core/2.Processing/Jobs/GenerateSurfaceTrianglesJob.cs(235,55): error CS0117: 'Status' does not contain a definition for 'OK'
Hope this is going to be continued. Crazy to me a CSG level design workflow isn't part of Unity core.
