Hi David! Yes I am using the CS rule. Always modifying (probably not for the better) to these crazy Nashville projects. haha
It was nothing bad on your end. You wrote the "CenterLineReporting-->" to revert to a color() function if the user wants Usage instead of Thematic. For some reason that was throwing off most of the textures in my Lite Rail assets. I just simply bypassed with a boolean..
I will certainly share. I have attached the code, models, textures here.
It is not very accurate or robust..but I primarily just need these things already in place when I go from CityEngine to animation software. Its a huge time saver.
As for intersections...I have just been adding the missing track manually in the animation software by projecting the track texture onto a flat plane that is at the same elevation as the intersection (cheating I know, but I have not found a work around in CityEngine for adding tracks to intersection ...and thankfully I dont have many intersections in this project)
If you would like to add onto CS and try making lite rail mode more permanent that would be awesome. Let me know if you need anything.
