File Description: This spreadsheet allows you to view, edit and save changes to the outer terrain's GTL tiles. Tiles are loaded into a 256x256 grid and the 13 default terrain textures are represented by cell background colours, i.e. the Mesa texture is represented by a reddish-brown background colour. The controls for loading and saving tiles are deliberately located on a separate worksheet. When loading and saving tiles I recommend that you do NOT select the main FU3 GTL Editor worksheet until a message box informs you that the load/save has finished. Otherwise, load/saves times (approx. 30 seconds for an average tile) will increase dramatically if you watch the tile while it is being populated or saved.
This 2.0 version also allows you to load a tile's terrain elevation. This is useful because the rules-based approach to modifying the OT was based on altitude constraints and it helps to be able to view the elevation (on the same scale as the tile itself) when modifying the terrain. However, in order to load the elevation you must first load the corresponding GTL tile. There is no provision to modify or save the elevation, because we already have Andre's excellent tools for that.
A complete map of the outer terrain's 2296 GTL files (plus Andre's 164 tile extension to the north) is provided in a separate worksheet. This includes a search facility you can use to identify tiles based on FU3 world co-ordinates.
