i`m workin on a track of 27.84 km (SS Panzerplatte WRC08 acc gps data with nasa altitute correction) with over 35 crosssections. It works since version 5.0. But i dont use trees or objects now, only terrains (48pices). At the begining of the work the real lengh (30.48km) btb load, but RBR does not load! (only street, no terrain, no objects etc.)
