<trackname>.GRV - Racing Groove

This is a file that tells trk23dow where to create the racing groove, and what darkness to make it. Example file:

The first line does not matter: it could say "this is my groove file" - it is just a line for the editor-person. The rest of the lines are in this format:

- Number

- Lateral Position in metres

- Darkness setting from 0.0 (invisible groove) to 1.0 (solid groove). Setting sections to 0.0 will stop trk23dow from creating groove polygons for those parts of the track (FPS saver!).

- Longitudinal Position in metres - distance from the start of the track.

- Lateral width of the groove in metres. This lets you create fancy things like a darker section covering the grid boxes, for that added touch of realism. The groove is centred on the lateral position, so half of the lateral width is each side of that.
