Warning: Nanite Landscape is still experimental in the engine and it has several engine limitations and bugs. Keep that in mind when using, I cannot fix the way Nanite works within the engine or with Landscapes, that is on Epic to do.

To Enable Nanite on a Landscape, first make sure that you have enough ram to do so. Nanite Landscape uses an enormous amount of ram in UE, even for blank landscapes without a material on them. Nanite Landscape is not meant for massively large landscapes, and if you do not have that much ram, would keep your landscape size to 2km x 2km or less.

SOME NOTES AFTER TESTING OUT NANITE LANDSCAPE AND NANITE DISPLACEMENT IN UE 5.3:
We will possibly be moving over to Nanite Displacement for the Landscape. I tested out Nanite Displacement in 5.3 – there are some current engine limitations. Nanite landscape seems to currently require a huuuuge amount of ram – larger than 32gb – on anything larger than 2k x 2k, even with just a default blank landscape and the default checkered engine material. This isn’t anything project specific. This will happen with any landscape, with any pack.

Still, I’m thinking I’ll set up some Displacement stuff (converting WPO to Disp) in the next major update to M4, getting ready for if/when we go that route. Nanite Landscape “works” in the engine just, still, not super well yet. So use it with caution.
