Hi SomaSin, since I answered you earlier at Studio forums I've done a bit more looking into this. Since it looks like the roads are objects you can clone them as a default override using Studio's debug thumbnail list. If you type road into the search bar this will give you a list of all the EA debug items that have road in their name. Once you've cloned the road Studio will pull all the resources into the .package for editing so, if all you're planning on changing is the textures, you should delete the unused resources from the .package afterwards in the Warehouse. This will allow you to make your default override item using Studio's model viewer preview :)
