i am a beginner. Try to do this: https://docs.unrealengine.com/latest/INT/Engine/OpenWorldTools/Grass/QuickStart/3/index.html
i do it 3 times now - the result is always a complete black thing and i always get errors: Warning Landscape_0 Instanced meshes don’t yet support unique static lighting for each LOD. Lighting on LOD 1+ may be incorrect unless lightmap UVs are the same for all LODs.
What i am doing wrong? i think i did it exact how it is written.
