BLK OPTIMIZER
Upload a .blk that War Thunder refuses because it holds too many BLK objects. The optimizer reduces the object count, never touches your uploaded file, and hands the result to Draw Sight.
Non-Hub-Thunder sights use a much smaller grid A .blk file made outside Hub Thunder usually stores its coordinates in a far smaller grid, so its preview looks like a tiny dot instead of a sight. That is the file's own scale, not a fault and not something the optimizer changed - the preview is never rescaled, because scaling a sight up that far turns it into an unreadable smear. Enlarge it by hand in Draw Sight: usually about 500x in x and y. Hub Thunder's own sights are drawn at their correct size already.
