@Kvazimodo - Yes, you will not want to use one large landscape component, you will want to use a decent-res landscape actor with multiple smaller components for larger levels - As for the texture set limit, this is due to the texture sample limit within UE4 and the way i had to setup the material to work correctly so there really isn’t much i can do about this right now.
@Paulhaydock1982 - If you’re referring to ‘Splatt Maps’ then yes, you can do this but i don’t have it setup within the material, you would have to add a node tree multiplying each of the texture set layer groups by the RGB channels in that splatt map like i have referenced in the below image for the Diffuse layer group - I would also recommend tying that splatt map to a tiling node tree so you can adjust it’s scale.
