I am not a skinner. perhaps we can found somebody who is.
I agree.
Does someone help us?
Btw, even your skins seem to me acceptable - as asphalt coverage -see photo in the first post of this thread.
Non-non.
Need weathering... Representation fugitive dust or lines / road are dirty , etc.
Question : is it possible simply change your tga files, please ?
It's easy and possible.
Even though the skin is not finished, you can use my 3D parts on your map making.
Before releasing the map to the public, only swapping the tga files into new completed ones, it's OK.
But....
Perhaps the texture similar to default concrete runways might be an alternative ?
I don't recommend using default concrete runway texture as highway.
Asphalt coverage and concrete are different in seen.
