| And so far I've never seen anybody do smaller than 256 grid size terrains, but maybe at this point you can already calculate yourself how small those terrains would be. | And so far I've never seen anybody do smaller than 256 grid size terrains, but maybe at this point you can already calculate yourself how small those terrains would be. | ||

| + | ArmA and ArmA 2 terrain information has been disabled now as the info we get from WRP doesn't compare with what we have ingame. For example ingame Chernarus is 15.3km x 15.3km in size, however the WRP says grid 2048 and cell 30m... Stay tuned :) | ||
