Hi! I am making an ArchViz project as a tech artist, and I am using the City Sample vehicle system that spawns cars on connected zone shapes in my own project. Cars use their own physics from the source project; speed is about 25 mph, and they are more alert to obstacles rn. Roads don’t use Nanite.
In the UE editor, they behave normally. But when I pack a build, they drive around for about 10 min, then they start causing traffic jams and sometimes disappear or fly up. They seem to occur at equal distances from my camera. And when I fly farther away, cars seem to continue their trip. I suspect that It has something to do with changing car representation from physical to simplified version.
Does anyone know how to fix it?
