In the last update those features got added to the world editor, but how do I use them? I could not find anything in the Documentation (that is still very bare bone regarding traffic) or a button in the Editor itself. Thanks in advance
For traffic, take a look at Automation Test Track's info.json. Line 46 "roadRules". Speed limit zones (city.sites.json) are done with (Window > Gameplay >) Sites Editor. Couldn't figure out how to add vertices or create them for a new zone. It seems to be quite crash prone.
Thank you, I was going crazy looking in the decal road editor. Having the speedlimit not based on the roads but actual zones makes things... interesting. Sure, this is perfect for residential areas but very fiddely for country roads with changing limits, probably way too fiddely to be usable.
