So using BTB, can you basically import any 3D model or textures and make anything? For instance, I would be making a track for RBR, but is it possible lets say to just make a full tarmac racetrack such as a GRID track by making new models and textures, etc? Or lets say for the hell of it, I wanted to make a futuristic space alien map or whatever... or lets say a cartoon map? Can I import any 3D object (which format OBJ DXF, etc?) And I assume any textures can be added? What about making Cars? Lets say I wanted to make my futuristic game with space ships hovering above the ground, is that possible? Can you tweak physics and other things? Can you import animated textures? What about sound effects? Cheers!
