Good news!
Race Track Builder has been released to steam as of 20/08/15
The first title with 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.

:D
So is it Piboso who makes it compatible, or the maker of the track builder? Because this looks like a major improvement over BTB
$60US :o :-\ :'(
If it exports out for rfactor... then it should be the exact same process for RTB as it was for BTB
Ive purchased RTB and there is not worth the buy at this stage. Has barely any features at the moment. BUT, as features come along, it will be worth it :)
