I did create a track surface with elevation changes. My problem is when I get half way up the hill I fall through the road surface. But even stranger thing is when I remove the groung plane below the track I no longer fall through the road. Any ideas where the problem might lie? With A Ground Plane: Without Ground Plane :
We've seen this on other tracks created with BTB and brought into rF2. I've not investigated, but it seems to be the result of two layers of driveable surface (or collision?) being on top of each other.
