Can you automatically draw a brushstroke on terrain that follows path defined by a decal road? Decals cannot change the physics/GroundType of the underlying material painted on the terrain. To achieve the desired change requires painting the terrain underneath your decal road manually. In other software like Photoshop it is possible to draw a path and then have a paintbrush automatically paint a stroke that follows that path.
I have managed this before. Through a complicated process... Basically took the road decals file, pulled the coordinates out and plotted them on a graph (basically a road network), then used that graph to create an alpha of the roads, then imported that alpha through the terrain import tool. It was a faff, but it worked. I imagine someone here could make a tool to do it though. It's always felt like a missing feature for me. Lay decal > convert terrain tiles more than X% covered to Y terrain type. Makes too much sense.
What tools are needed for this process? Where is/what is road decals file? If I can figure out a way to convert coordinates a curve in blender, I already have something that can generate an image quickly. https://i.imgur.com/qt9VLXr.png
I just used excel if I'm honest. It was very much a bodge on my part. Used GIMP for the image stuff. Files are all in the map folder. It's in your user directory. Can't remember the exact location.
