Nature Environment in UE4

Thanks, it was what I needed!

@all

  1. I’m not sure, should be grass normal looks straight up or be bented like in picture?

  2. Have the material of the grass to be “Tangent Space Normal” = off even with edited normals? If I set on, I get dark grass on some angles to the sun, the edited normals of the grass are looking straight up

  3. I have some strange lighting behavior of the grass. If I look from some distance and the sun is behind me (so I look at side of grass which is shined by the sun) the grass in the shadow is very dark (pic1). If I go more near the grass (pic2), the grass gets brighter. Same if I look from a higher position, the grass gets brighter too. If I go to the opposite side, so I look at the sun and face the side of the grass which isn’t shined by the sun, the grass is brighter.



my grass material:

  1. should I set the grass object normals to two-sided in Blender?

  2. Should I by importing into UE4 set “Import normals” or “Import normals and tangents”?
