Ground showing up through track?

I have seen this posted before, but I cannot find the thread. How do I keep the ground texture from covering or looking really weird through the track? I have tried both PBR and non-PBR textures with no luck. What's the trick? Never had this issue before.

Without more specific information I would say that this is a PBR texture issue. You stated that you tried non-PBR textures but does the track use PBR for its ballast? The problem seems to occur when the two, PBR and non-PBR, meet.

What is your Shader Quality setting in the Trainz Settings Performance tab? If it is "Ultra" change it to "Standard" to see if that makes a difference.

Thank you!!!!! I kinda remember having that problem before, but this old mind didn't have a clue as to what the solution was. I guess that with the new 'puter I could run everything on max.
