L3DT cannot do decimal cell sizes.

If you can avoid do not create terrain cell size with decimal points, like heightmap 4096 * cell size 7.25 etc. This only applies for Global Mapper, Wilbur etc created terrains.

While ArmA 3 cell sizes with decimal points work fine, you should still try to avoid them. Well try at least a bit, if you have a choice to create a new terrain it absolutely should be without decimal point cell size. Most bis terrains use decimal point cell sizes, again as said there is nothing wrong with that but L3DT wise… you get extra work because L3DT cannot do decimal point cell sizes.
