That doesn't really matter, you don't need every single pixel from corners, you know...
Actually you do, and i don't need players who own CS:GO to help .. if you know how to Code, make models or prints and even music youre welcome to help but if you want to build you must have the game becouse De_Dust 2 had alot of changes and updates so most of the pictures you'll find on Google are not updated and that can couse alot of trouble to the map like my admins sead i'm making this map the exact copy of the real one every thing needs to be perfect. right now the map is standing on about 35%-40% done you can still join and build small objects as Boxes, Lights , cars etc ... i'll be happy to welcome you :D
