VDrift roads in Blender

[NaN]

I've added roads.trk import and export functionality to the blender25 plugin(needed it for gui work).

A track supports multiple roads. A road is a patch strip. A patch consists of 3 quads. Road patch connectivity information is encoded into uv coordinates.



Howto generate uv coords in blender:
- Select the first patch of your road in edit mode(3 quads).
- Uv Unwrap patch to fill the uv rectangle(see image above).
- Select all faces.
- UV Unwrap/Follow active quads/Equal

The export is experimental atm. Interpolated patch points deviate by up to 5% from the original ones. Haven't figured out why yet.

I'll create a new video tutorial as soon as start positions import/export is ready. Then it should be possible to create the track completely in blender.
