How do I get the LandscapeHoleMaterial?

So Im testing out the sculpting with lanscapes and wante to make a tunnel/caves and so on… But I dont have that one material so where do I get it?

Well ok… I did tutorials and found that out witht he material editor. Now I got the next problem… Int he editor details I cant find the Landscape option where the Landscape Hole Material should be…

I really dont know what to do, please help me! D;

Select landscape → Landscape dropdown ( click to show hiden options) → there will be land hole mat slot

well if it would be there ii wouldnt ask… I really dont have it anywhere

if you are using world compos ( or other lvl streaming system) you need to load this lvl separately, otherwise this option wouldnt be present.
