My Problem are strange Shadow Effects on the Grass, I checked the Tutorial twice and the Material should be right, but I can’t find the probem with the grass. I also tried different lighting settings, like setting every light movable. Furthermore, I changed the Material settings from “Default Lit” to “Subsurface” and “Two-Sided Foliage” and nothing seems to work. I even deactivated the static lighting in the project settings.
I had the very same issue, fixed by checking all the normals of the mesh. For ex. in 3dsMax: Editable Poly–>Edit Normals modifier–>Select random normal that already pointing upwards and click “Copy Value”, then select ALL the mesh normals and click on “Paste Value”. Done. All normals must be pointed UP (in case you aiming to reach the same effect of a full lighting).
