When looking at roads in West Coast USA, it appears as if many of the road areas are sitting above the ground like a decal would be. Except, these decals are huge and cover many of the roads completely. https://gyazo.com/449021c498869ad9996a187a7d1dad8c However when editing the map, it looks like theres a large decal over the roads that holds all of the decals. For instance I can move the lane lines and dirt/skids around, but its all contained on that layer above the street. yet there's no z_fighting at all? What is this sorcery? Am I a decade behind in how this all works? How do you make this magical decal layer on top of roads? I have so many questions and I don't even know some to ask yet because this is all so new and cool. EDIT: Are the roads 3d models or terrain? If it's terrain how are they all so precise? High resolution heightmap?
There is an option render order or layer order. Can't remember the name but it's an attribute that sets its z priority. Default is 10. If its 9 its rendered on top of 10, if 11 its below. =) --- Post updated --- It's called, "Render Priority" so figure it as Z priority. Higher numbers are placed LOWER and lower numbers. . . are placed higher. 0 is always "top" layer. So If you're doing a road with a lot of details, set the first layer to 20, then the surface on top of it would be 19, 18, 17, etc..
