The route is loaded with old 4-sided bushes/shrubs splines along the tracks. They are Packaged. How can I delete them from the route? This is a purchased route.
You can't, unless you create a copy of the route. Or you may choose a more realistic spline (this one from DLS or locally modified), open it for edit, change its KUID in order it obsoletes the one you don't want to see, then import it.
