====== ArmA 3 Terrain Separate Data\Layers into Smaller PBOs ======

**How to separate your large ArmA 3 terrain Data\Layers PBO into individual PBO files.**

First read the [[arma2:terrain:separate-data-layers|ArmA 2 version of separate terrain data layers]] for some background understanding, there are some details which we don't need to repeat.

We take the single WRP addon dir and separate it to following: WRP (it remains as is), Data, Layers (RVMATs) and Layers_00 (PAA) through how many numbers you have, however this tutorial uses 00 to 08 range.


====== _run_Separate_WRP_Dir.bat ======

This batch file does all the heavy lifting when separating your terrain addon directory. In our example we use "pmc" as our mod / group tag and "pmc_iraq_baghdad" as our addon name. Put this bat into "pmc\pmc_iraq_baghdad\Source\" directory.

You only need to edit "set MODTAG=" for mod / group tag and "set TERRAIN=" to replace our terrain name with yours, rest of the batch file is OK.

====== MoveObject RVMATs ======

You must fix the paths in layers RVMAT files, use [[arma3:tools:mikero-tools|Mikero Tools]] MoveObject for this task.

See how to use [[arma3:batch-file-examples#rvmat_files|MoveObject for RVMATs in batch file]]. Put these bat files into pmc_iraq_baghdad_data_layers\ directory.

Here is our example replacement text file, you obviously need to make your own using paths to your terrain (both mod tag and addon name).

RVMAT **_MASTER_paths.txt:**
<code>
pmc\pmc_iraq_baghdad\data\layers\s_00 pmc\pmc_iraq_baghdad_data_layers_00\s_00
pmc\pmc_iraq_baghdad\data\layers\m_00 pmc\pmc_iraq_baghdad_data_layers_00\m_00

pmc\pmc_iraq_baghdad\data\layers\m_08 pmc\pmc_iraq_baghdad_data_layers_08\m_08
</code>
Then just run _run_update_rvmat_list.bat and _run_moveobject.bat files to mass change paths into all your RVMAT files.


====== MoveObject WRP  ======

WRP needs its RVMAT paths changed because we moved RVMATs to a new directory / addon.

It is basically the same as what we did for individual RVMAT files, see [[arma3:batch-file-examples#wrp_files|MoveObject for WRP in batch file]] for file name details.

WRP **_MASTER_paths.txt:**
<code>
pmc\pmc_iraq_baghdad\data\layers pmc\pmc_iraq_baghdad_data_layers
</code>

If you forget to change RVMAT paths in WRP file, then none of the above works.


====== Re-Generating Layers ======

In the future when you have ran through this tutorial once, have WRP dir separated / split all nicely and then you need to generate layers again... you have to delete the existing directories created by this bat file.

It //might// work that you just let it overwrite dirs / files, but it is best to just delete the existing **_data**, **_data_layers** and all **_data_layers_0X** directories.

So store the MoveObject RVMAT batch files in your pmc_iraq_baghdad\Source\ directory for safe keeping from any deletion.


====== Buldozer ======

In this separated / split setup terrain builder + buldozer cannot find the RVMAT files, it attempts to find them from pmc_iraq_baghdad\data\layers\ directory, but instead they have been moved to pmc_iraq_baghdad_data_layers\ dir.

You can easily fix this by making a symlink "layers" directory into pmc_iraq_baghdad\data\ directory.

**_run_create_layers_symlink.bat:**
<code dos>
rem do this on WRP\data\ dir
mklink /J layers C:\armawork\PMC\pmc_iraq_baghdad_data_layers
</code>
**Warning: You must delete this "layers" symlink before pboProject binarizing & packing your terrain!** if you do not, then pboproject will try to copy the rvmat's into p:\temp\ and its going to be a real mess.

Howto delete symlink:
<code dos>
del layers
</code>

You cannot really change the path from terrain builder project settings, because it defaults to <project>\data\layers\ directory, so you cant set it to any dir which would match pmc_iraq_baghdad_data_layers\ heh.


====== Reference Altis PBOs ======
