Works here too. Now i have some questions. I have compared my and your file. And my file also works, when i add the entry "CUBETF_NOZBUFFERREQUIRED", to the last section of the file. Question: why wasn't that entry written, when i have selected the trackside monitor shader and saved the json file in the material editor? What could be the reason? And finally, why does the mesh with the correct shader attached, directly exported from 3dsmax don't works (without a json file), no matter if i check or uncheck add zbuffer? I can wait until LM is over, to get an answer.
It's not necessary. Create your model, give it a T1 Shader and put it into the track. Download the json file from this post and do what @Alex Sawczuk has written there. Then put it into a folder of your track and link that folder with the entry MaterialPath=XXX in the tracks scn file, where XXX is the path to the folder (similar to the SearchPath= entries)
It works in devmode. Did you rename the json file, that it has the same name as the used monitor material?
Not in every case as it seems. As reported, my own generated json file, with the proper shader selected in the material editor, did miss some necessary entries and didn't work.
It works, i put your files into my private test track and it works. Have you done everything that i have written above? EDIT have you put the below line into your scn file? MaterialPath=dover2017\Assets\Shareds
