Hello n00854180t and ambershee,
You are both right from a far the sand looks rather uniform. However close up it is detailed and uniform is better than visible artifact. Think I can adders that by adding another macro distribution texture.
See image for closeup of the sand:
That is a good point, I am adding a setting that controls the specular/wetness on the shoreline. To make things more believable. The feature is already in the materiel and has been used before to make snow on mountains look specular.
The plants are just a test to see if the performance is OK the have not been placed in the map with any artistic considerations. So there is room for improvements.
I think I can get variations on the leaf Material in a procedural way by looking at the world position and adjusting some of the parameters.
I post the results when I have them.
Thanks for the input.
