Hello all, I made my fisrt stage, with BTB (Thank you very much Brendon, for that great tool) This is Turkiye WRC 2008 Antalya SSS.Yet far from finishing. After finishing first steps, and getting stage overall generally, I wanted a short test drive (lack off patience ) I had succeeded at my previous attemps, with some other unfinished tracks. Everything was fine. BTB exported the track, and RBR loaded it without any recognizable problem. But when its loaded, the stage was up above my head and the car was hanging in space for an instance, and than started falling down. Hope to know; What did I wrong to make this? What I did different at this track from my former track attempts; is to set the "y" values for all the track manually, to the real height which was between 20 and 30. And How can I solve this ? Thank u very much for ur precious helps.
