Haha, if only you knew how right you are !
Indeed you can replace each texture by what you want !
You are totally right, Dave, for the moment there is no rules to make the roads, we can make any non-sens we want, and we need to specify each evidences.
This will be the next major step, to create a high level more user-frendly, by manipulating objects instead of splines that will automatically create the more logical spline between them, like in simcity games, then if we want to customize, we can convert it to object and edit the spline inside.
I think it will be the more complex because each country seems to have custom rules, the community will be a great help to that !
Indeed, the inclusion with RealTraffic can be possible, I will check that when the plugin will be more advanced.
I also think to make a website after the plugin, to create roads in a web app, without necessarily C4D.
Thanks for your messages, I am back from vacations and continue the work !
Some things to fix, then I will start to make central reservation and sidewalk and after that I will see to make a private alpha release to have some first feedback if some of you will be interested in testing.
