In the first picture, I added some background scenery (cliffs, more trees, enclosed fence) and a single grass mesh. Can you spot it?
In the 2nd picture, I experimented a bit with splines and the landscape sculpt and paint features.
I haven’t used Unreal Engine since way back in the day when your work flow was based on subtracting volumes (you started with a giant block of solid matter and then sculpted rooms and such out of it) - I’m really impressed and also kind of overwhelmed at all the changes and new features - especially the landscaping stuff. At least the viewport controls are more or less the same!
