You can trial the very latest BTB Pro version for a period of 14 days after which time you would need to
purchase a license.
This version contains all the same features as found in the Pro version. You can build your own tracks, load GPS data, export to rFactor or Richard Burns Rally, load your own textures and create your own materials.
The only things missing are the large material/texture packs that expand the number of surface textures available for initial use.
