I also tried making a transition so that the road doesn’t end up being tilted at the other end but the transition is way too visible and will cause a bump to any vehicles driving by.
Can someone suggest a technique or a plugin with which I will be able to do that?
best way at my knowledge is doing it with blender, it’s way better to make those type of tricky road, archimeds work too, but is kinda more tricky since you have to put an X and Z rotation, one way could be to give your road a curved rotation by default
