Race Track Builder is a software design tool that has a simple, easy to use interface that allows you to build fantasy race tracks or use Google Maps data to create real-life terrain and roads.
Free Upgrades
Additional functions will be added as free upgrades as they are developed. These include many of the more popular BTB items integrated into the new interface.
Objects
String-Objects
Walls (with proper ends 
)
Intersections
Expansion Packs (Xpacks) including additional textures, materials, objects, cross-sections definitions.
... and a few surprises.
RTB will export to the Autodesk FBX format which can then be loaded into 3d modelling tools for export into games with a little more work. This opens up RTB to more game developers and this in turn will generate more RTB content (XPacks) for people to use across all types of games. In time export direct to game may be added for some titles but initially the focus is on supporting many titles.
The first title with specific support is Assetto Corsa with materials and shaders created to replicate the shading used. The landscape uses Multilayering shading with support for direct modification of the underlying texture. When targeting Assetto Corsa the export prepares the objects ready to be imported into the AC Editor, generating the Configuration file so that materials and textures are applied as they appearred in RTB.
