Multiple Landscape?

Hi Forum

I am currently doing a landscape where I’m required to utilize two or three different landscapes within the same Unreal Project, because the locations visible to the player are spaced a bit apart from each other. by a frozen lake. My question is; does putting in multiple small/medium size landscapes take a tool on the frame rate/processing power needed to run the game - compared to one very large landscape? Does multiple landscapes in the same project in any way damage to overall technical stability of the game?

Anyone who can enlighten my on this?

I would thinking creating one large landscape with the different binomes you would need would be the best/easiest route as it only needs to render once instead of each landscape/plane individually.
