Track sinks in 2019 and 2022

[Jersey pete]

I have been struggling trying to get my track to appear when using TransDEM in Trainz 2019 and 2022. It just seems to disappear underneath the baseboard. I have the rails sometimes and just the markers other times but never the complete track. What am I doing wrong?

I don't think you are doing anything wrong. In early versions of Trainz the splines clung to the terrain surface. They no longer do. It's probably just a bit flag in the spline points. However, I have not been able to figure that out, even by comparing binary data of Surveyor laid track and TransDEM laid track. And N3V wouldn't bother to reveal specs. So I gave up.
