Why Road Editor Asking for new terrain. Why can't i apply it to my dae level? EDIT: Reason why i need road editor is for the AI. (tell me there's other way to get ai work on?)
Create a blank heightmap terrain to go underneath your dae based terrain. Since you won't be using it make it a low resolution and stretch it to be around the size of your map. The standard road editor can only build roads onto a height map since it applies a texture along a path to the heightmap. For a Dae based map you would have to use the 3D roads. i'm not sure if you need a heightmap for 3D roads to work, so I would try using them first before creating a heightmap.
Is there's other way using decals road editor? then using heightmaps? if there's none, could u link me the video how to make AI road with heightmaps?
My best guess is that you would place the decal roads under the terrain so that when you look from above they line up with the actual roads. But I am not entirely sure.
