====== ArmA 3 Terrain Processor ======

Terrain Processor is basically object placer. Its like enhanced version of Shezan74's World Tools (no relation though).


====== Project Templates (TPP) ======

PMC has provided full project templates for download, see [[arma3:terrain:terrain-processor-templates|Terrain Processor templates]].


====== User Guide ======

Terrain Processor (TP for short) is a bitch, you make one slight wrong configuration and BANG it crashes or freezes without mercy :)

Project *.TPP files are XML format, you can edit them but as bis TP manual states its not advised as its easy to make mistakes and again TP will crash, so be very very careful.

You should name every TPP project file with very descriptive file name (normal rules apply, no spaces, no stupid characters) so you can re-use them with other terrains in the future.

It is cumbersome to add object template names into the projects so once you do it, save the tpp file that you don't have to type in all those templates next time you want to place forests etc. Also inside <ObjectPrototypes> you can use text editor to copy paste from area random into high density cluster.

**Area: High-density Cluster**, if you drop object probability to 2, it starts to really slow down the object creation.


====== Road Smoothing ======

**Heightmap: Road integration**

Does TP place your smoothed out roads 500m below ground?

Shapefiles must be within the mapframe bounds before using TP to flatten the road surfaces or you will end up with super deep valleys carved into your terrain heightmap.

If your road smoothing will carve almost tunnel like pathway to the terrain even though it is not even that steep, you can fix it by increasing Road Maximal Slope.

If you have problems loading terrain builder exported road shapefiles, try loading and saving them in global mapper (or QGIS?) first.


====== Object Placement Statistics ======

This is nice reference read of how many objects some configs place and how long time it takes to import these to terrain builder. Computer used to create these statistics is CPU: AMD Athlon FX-4170 4.2Ghz Quad Core Black Edition, RAM: Corsair Vengeance 16GB PC3-12800 1600MHz.

Task: Area Random

Trees 12, probability 100%, minimal distance 5m.

**Polygon size about 20km x 20km**, just slightly below that size but otherwise square area.
