Modding is a strong side of XMR.
XMR Editor allows adding tracks and cars to the game.
You can import any 3d model (whole track/car or single object like tree, house, driver body, tire etc) from 3ds Max. You can also create your own track without 3ds Max.
Tracks and cars are saved in a variety of ways.
.tdo – single or some objects of track/car/object.
.wld – world project that contains system info about a scene.
.we – world environment that contains all materials, markers, cameras, lines, system information etc.
.trc – texture packet. All textures must be as .tga files.
.mtl – materials of scene/car that can be imported/exported.
.mss – markers of scene/car that can be imported/exported.
A typical algorithm of car making:
1. Creating/importing 3d model with textures in 3ds max, but without materials. XMR uses its own material system.
2. Exporting car from 3ds Max as .tdo to XMR Editor with exporting plug-in (can be found in XMREd\3dmax_export_plugin folder).
3. Graphics materials.
4. Physics properties of all bodies.
5. Suspension and wheels.
6. Damage model of external body.
8. Damage model of cockpit.
9. Exporting to the game.
10. Sounds of car.
11. Physics model of car.
