This is a QGIS plugin, meant to get source files used for virtual terrain creation,
based on real world dat. Primary target is Arma3 and DayZ, more games will be added in future.
This is not an editing program, use L3DT for that.
The basic usage consists of getting easily accessible and globally available data,
however because it's a QGIS plugin, you can add whichever other sources you want,
and have this plugin take care of your resampling/translation/required formatting needs
Plugins on top menu > Manage and Install Plugins > Install from Zip > select gameterraintools.zip
Important info for beginners
This is the basic usage of this plugin, if you want to know how QGIS works, read a QGIS guide.
This is also not a guide on (arma) terrain making, if you have no idea what any of the settings in this plugin do,
even after reading this entire README, then I suggest turning of your brain, following the steps listed in USAGE
blindy (Dont randomnly change settings to what you think they should be. The default settings are correct)
and then adding the exported files in Terrain Builder
For more arma-centric terms in regards to mapframes check the general notes. For basic usage I recommend
using the OSM mask option, for the regions of interest method please check the guide.
It will have far better results, but does require actually reading the guide and patience to use it.
Add a satmap source (Find one yourself or select a source and press Add Satmap)
Save your QGIS project somewhere (Ctrl+S)
Set map size (Width/Height in meters)
click Mark Area, left click map to select that area
Download Roads (Also required for mask export!)
Check the exports you want
All resulting exports go in a gtt_export folder located at your QGIS project location
A file gtt_export.txt will contain info with corresponding values for your Mapframe properties
Map Area is the only thing deciding the size (in meters) of your terrain.
Scaling is the size for export. Marking 20k, then checking scaling and setting it to 15km,
means that everything will be scaled down 25%
You can add your own files, and let the plugin handle the processing (Fixing resolutions, making compatible for engine)
by dragging in the files and then renaming the layer (Select layer and press F2) to what's listed below.
Single layer gtt_satmap is used for this. Any custom sources should be given this layer name.
Resolution is the total resolution you want your satmap (and mask) to be. Use -1 to ignore (1m/px) (Recommended)
For large satmaps (20k and up) you should check Tiling and set the size in pixels for each tile. this is before resolution / scaling change if used
Allgtt_heightmap layers are used. Cleanup ones you dont want in
The gtt_heightmaps will be merged automatically.
If a manually added source does not export properly, report issues!
Single layer osm lines is used, you can make manual adjustments before export
This currently does not do any checking on allowed surface per tile (6 per tile for arma)
Single layer osm multipolygons, you can make manual adjustments before export
The Shape based implementation is heavily dependent on available data for that area
