You can drag and drop .gmte files onto the window and you can also associate and open .gmte files with GMTE 2.exe:

Use the included "Associate GMTE files with GMTE 2 exe.bat" to associate .gmte files with this program and give them the same icon. Use "Remove GMTE file type association.reg" to remove the association ("using" means double clicking). If the bat file doesn't correctly set up the associations (e.g. because you already did manually), try running the .reg file first. You might have to restart explorer.exe, log off and back on or restart the computer for these changes to take effect (at least for the icons).

You can put custom 256x256 textures in png format into the "Textures" subfolder for use in the program.

Exporting & using maps

In Game Maker

Export the map you wish to use in the program as d3d (rightmost button) - the d3dexport folder is created. A very rudimentary loading sample is included: "GMTE 2 - Loading Example.gm81". Copy this file plus the d3dexport folder to a new location and build your project from this - or merge your existing project with this project.

In other programs/engines

Use .obj, heightmap and texture export for other programs.

When drawing the exported obj, make sure you draw it with texture coordinate mode set to clamp, not repeat. For best results (with mipmapping/linear interpolation), make sure the textures have a size that is a power of two (by making sure pixels per path * patches per model equals a power of two).

Unfortunately, the heightmap is only 8 bit so the precision is not that great. 16 bit greyscale png and raw support should be added...

See "ReadMeForSourceCode.txt". This project is completely open source. Let me know if you create something cool with this!

Final Words

Feel free to redistribute this package unchanged and non-commercially! Always include this ReadMe (also unchanged) and do not claim you made this software (though there are certainly people who contributed a lot to this without even me knowing...).

Thanks to "Yourself" (from the GameMaker community, for the mouse 3d-2d projection maths) and the artist(s) who made the Age of Mythology ground textures (a few of those are used in this program for demonstation purposes) and who made the music for Age of Empires 3 (used in the demo video for version 1) and of course also thanks the everyone else involved in the making of these games and to the creator of the Game Maker, to many people on forums and to everyone who made computers possible - this wouldn't have been possible without you xD!
