This is visualized by the CargoUnit.trailMesh component, which other than needing to be initialized and disposed of during scenario resets, takes care of itself without much need for us to intervene. We need an equivalently hands-off way to similarly render visualizations for encounters when and where they occur along the route, and that’s precisely what the work we just covered is meant to enable.
