In this tutorial I will show you how to map BTB imported terrain without distortion because of poly shape.
Whay this is important? Because you can create your track with the terrain in BTB and you can in max use same dds file for your track as well as for your terrain (TrackTexturePlateOpaque.dds). You can now attach and weld together the terrain and the track for further shaping and processing.

I will briefly explain what is in the video.
| Here is how my project looks in BTB. Notice the terrain above the curve. |  |
| Export your track from BTB. A usually export as rfactor, import into 3dsimed and export as single x file. When imported into max you need to first convert into editable patch and then to editable mesh. This step is needed so you can select polygons. |  |
| Assign material to your selected terrain (ttpo.dds) |  |
| Now select all polygons (ctrl+a) ang go to Unvrap UVW modifier. |  |
| in Unwrap window select elements checkbox and select Face object mode icon. Zoom out so you will see your terrain and select all terrain (ctrl+a) |  |
| Now the key element! Go to Mapping menu and choose Unfold maping. Select Walk to closest face and normalize clusters. |  |
| After a while you will get your mapping shaped into square so you can easly select all and shape into right square of your texture. |  |
| Now all you have to do is to exit unwrap window, colapse Unwrap UVW modifier and select all wrtices of the terrain and weld them. Now your track and your terrain will be from single material and texture and you can attach, weld, modify together. |  |
