1) Examining the forests and groundcover on the RWA Lakeside Route, I was surprised that I could not edit the forested areas. It's like the huge forested areas are a groundcover texture, painted on. However when I try to paint over them with a different groundcover texture, the trees remain.
Please advise how trees like that are placed on a route.
2) what's the purpose of the forest and farm 'marker' groundcovers?
