Not too bad I guess but it depends how optimised really. I plan on having a somewhat sizeable map small-big <–> medium-small so performance can be a must.
Not small to big but a map that is small however is sizeable for its size category. If that makes sense.
Yeah, what I can suggest is union the generated road between the CloneParts with the new beta feature they released or what you can do is make the segment length.
I have quite literally got every single beta on and also some mesh optimisation plugin too that I could probably use too help.
