[USER=“3140864”]MostHost LA[/USER] If you’re talking about tiled landscaep it’s a bit different; you have a singel landscape (sort of) with different landscape proxies. But in this case you can only only assign a singel material to the “main” landscape actor.

Or are you talking about something else?
