The grid drawn when pressing tab should be a little bit more pronounced – like the grid when in build mode. It seems like if you click “Reveal All” the grid is displayed nicely.
Can you elaborate on this one? The grid for Tab vs. Build should be identical, and are drawn using all the same systems in the same way, as far as I can tell. The only difference is that Build mode also brightens the scene. It should definitely be totally separate from fog-of-war- what does “Reveal all” change in the grid, exactly?
EDIT: Ah, nevermind, I found it. The full-fog effect is suppressing more outlines than it should be.
