MSGSapper,
Was the reason you scaled the height of your 132 lb rail mesh to 5 inches instead of the prototypical 7.125 inches due to causing errors in Trainz if the height of the track asset from the ground to the top rail exceeds a certain height?
I am currently creating a 136 lb rail mesh scaled at the prototypical height of 7.31 inches.
Blender screenshots of my 136 lb rail mesh.
Rail profile used to create mesh: Transport Rail 136RE (TR68) - ArcelorMittal
You are going to find that creating PBR procedural track is a very frustrating experience at times, even with all the source code I provided. There are real height tradeoffs between the following:
1. Track
2. Ties
3. Road bed
4. Maintaining compatibility with other track.
It took a lot of trial and error on my part to get it right. I expect rivet counter types trying to create 100% prototypical track will be giving up in frustration at some point. I wish you luck and this is the extent of my help to you on this, as its been some time since I last did that project so I don't remember most of it.
