After having migrated the development of Grid Framework to Git I wanted to set it up to track only certain sub-directories. I turned out that whitelisting is quite tricky, so here is how I did it for people who might run into the same problem.
Grid Framework version 1.5.0 has been approved by the Asset Store team. This version brings a great new feature for anyone interested in making isometric 2D games: shearing. Shearing allows you to slant a rectangular grid’s axes without having to rotate the grid. Up until now the only way to achieve the isometric look was to rotate the grid or the camera in 3D space, but in 2D games the camera has to be perpendicular to the image plane and thus the grid as well. Now all you need to do is just set the shearing of the axes and you’re good to go, everything else stays the way it was.
