I'm planning to make a circle plateau with using 15m Plain Wall Esplanade Road by PJC. but If I build Esplanade road, the ground is transformed. I want to change some options in class files so that the road doesn't change the ground. so I've looked "XLN_PJC_Seawall & WaterRoads_v1.6.patch" file which has a seawall that doesn't affect the ground. I compared class files looking for options that defines ground transformation. and I changed some options and tried in the game. but I still don't know which one should I change... Is there any tutorial or instructions about words in class files especially for roads and bridges?
