I know I made a similar tutorial on racetracks, but this is better since the complexity on the track can be almost unlimted without angle problems in the curves.
This will be in 5 parts
You an probably do similar with other tools but these are the ones used here :
- Silo2 - http://nevercenter.com/
- Ultimate Unwrap 3D - http://www.unwrap3d.com
- Giles - http://www.frecle.net/index.php?show=giles.download (free)
- 3D Rad - http://www.3drad.com (free)
Part 1 - Model the racetrack - http://www.3drad.com/forum/index.php?topic=7185.0
Part 2 - Texture and UV the track. - http://www.3drad.com/forum/index.php?topic=7186.0
Part 3 - Add the City and apply simple buliding textures.
Part 4 - Lightmap everything using ambient occusion lightmap (radiosity)
Part 5 - Setup in 3D RAD, and some tips.
This is Part 1
1. Start Silo
2. Hit 5 to get top View
3. Select from menu : Create->Edge Tool
4. Draw a racetrack path like this (PS! Use about same distance between vertices looks better when tetxuring)
5. Hit 1 to get to Perspective View, select the Vertex selection tool (bottom left) and adjust the track so you lift the road where it crosses :
6. Hit C two times to subdivide the path, then SHIFT+C to refine mesh.
7. Click the Edge selection tool at the bottom buttons, and hit CTRL+A to select everything.
8. Then Click Extrude from the left menubar and extrude along Y just abit like this :
9. Select the Face selection tool from the bottom buttons.
10. CTRL+A to select all faces
11. Then Click Extrude from the left menubar and extrude left or right, it should look like this :
12. Then delete the selected faces by pressing delete two times. As you see you have now 2 tracks on top of eachother :
13. Then delete the top track by selecting two faces (use shift to select two), and click Select Loop (from the left menu) to mark rest.
14. Your now left with one track like this :
15. Select the Object Selection Mode from the bottom buttons and then from the top menu
Create->Extrusion Object [opt] (click opt)
Fill in
Height : 0.1
Section : 1
Click Create
It should look like this now :
16. Create edges on track, by select 2 faces on one side, Select Loop and extrude. Repeat on the other side.
17. Select 2 faces on each top side, Select Loop and then extrude, like this :
18. Save as .obj (racetrack.obj)
