What is the best way to give roads better realism. i.e. Adding cracks, manholes, etc, so they don't just look the same as you travel along them. Are Decals the only option. Or can you do this with shaders? As you can probably tell, I am not a graphics guy If you have a large road system, is their a way to automate adding realistic effects. Or is the only option to add random decals so that you don't end up with an ever repeating pattern? If this achievable with tools from the Asset store, I would like to grab them before the sale ends today.
