====== L3DT No Decimal Points ======

[[:tools|PMC Editing Wiki: Tools]], [[tools:l3dt|L3DT]]

**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, [[tools:wilbur|Wilbur]] etc created terrains.

While [[:arma3|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 [[arma3:terrain:grid-cell-size|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.


====== Decimal Point Examples ======

L3DT cannot generate attribute / texture images using decimal point values in heightmap to image ratio. For example [[https://www.pmctactical.org/arma3/pmc-51km-desert.php|PMC 51km Desert]] is heightmap 4096 and cell size 12.5 meters, which L3DT cannot do, it does 12 and 13 but not the decimal point five.

L3DT generated satellite texture/mask sizes.

PMC 51km Desert 53248 x 53248 resolution image. Divided by four tiles comes to 13312 x 13312 resolution per tile.

51km desert\\
heightmap: 4096\\
cell 12.5

L3DT exports 53,248 res image with setting 13. This is 4x4 tiles 13312 res per tile.

[[https://www.vtemod.com/arma3/vte-gao-rung.php|VTE Gao Rung]] is 51.2km terrain, 4096 heightmap 12.5m cell size. Same as PMC 51km Desert above.

[[https://www.pmctactical.org/arma3/pmc-rattler.php|PMC Rattler]] and [[https://www.pmctactical.org/arma3/pmc-rugen.php|PMC Rugen]] 28672 x 28672 resolution image. Divided by two tiles comes to 14336 x 14336 resolution per tile.

heightmap: 4096\\
cell: 6.25

Mask AM/HF and Texture TX/HF ratio 7 gives 28672 x 28672 res. This is 2x2 tiles 14336 res per tile.
