I have written my own terrain generation and when I generate terrains, I get these patches of dark areas occurring whenever there is a “hard” edge.
There is a group of 9 quads which are less lit than the others.
I create the verts, triangles and UV’s, then I call RecalculateNormals().
I can confirm the following:
- There are no duplicate vertices.
What am I missing? Thanks in advance.
