Create a road along large terrain I created a terrain in blender. I have on it a base layer. The base layer comprised of two textures. These are a dirt and rock texture mixed together using another texture as a mask. On top of this texture I would like to create a road. I have another mask texture for the road. I am using tiling textures for the base layer, only the masks are non-tiling: they take up the entire UV space. The road also must be tiling somehow, I cannot create a 32k texture. 



How can I have a tiling road texture follow a path so that it looks like an actual road? This is an example of a tiling road that correctly follow a path. 



blend file textures are packed and set up is clear
Create a small section of road.



Add a curve to define the path the road will follow.



Back on the road section, add an array modifier, a curve modifier and a shrikwrap modifier. You set the array to fit the length of the curve. Then it follows the curve and the shrinkwrap sticks it to the terrain surface.



Giving a final result -



The curve can then be hidden. Or you can apply the modifiers and join the road mesh to the terrain mesh so they are one. Applying separate materials to each section of mesh.
