I'd like to add a few stats and facts:
1) There were 13 populations used in this render
- 5
HD pines-
Walli's Fresh Grass 3-
Walli's Dry Grass- 3 species of the
Dry Bush Bundle- 2 populations of
FrankB Better Grass (those are free)
- 1 population of Rock. I have used an experimental technique which might find it's way into the
Fake Stone and Hero Rock Pack
2) This was rendered on a core i7 8GB machine in 5.5 hours at 4000x2200px. The project needed over 6GB peak memory.
3) Detail = 0.7, AA = 4, GI = 2/3 + SSP
4) Again forgot the soft light :/
5) I have used the general purpose
camouflage surface for the terrain under the trees, which I have shared here on the forum.
6) An additional Enviro light set to ambient occlusion was employed with 0 strength on atmo but 1.6 strength on surface
7) the color of the background sphere was set to 0.35 to help the GI algorithms catch some light

8 ) The "beach" uses the
Sand Shader Pack from TU

I had a lot of fun and will do more like that

Cheers,
Frank
