I am new to creating my own tracks and I have hit my first hurdle. I am using Bob's Track Builder which thus far I have found unbelievably easy to use. When I use just a normal cement wall it exports to the game just fine. When I export the same track with a cross section (which is want I need) on the cement wall when in game it only shows the cross section. If I drive under the cross section then the wall appears. Hoping this is an easy fix as it is very important as I am creating dirt ovals which require the cross section. Thanks in advance for any and all responses.
