Mountain terrain from a displaced grid, with water

Mountain terrain from a displaced grid, with water. A real render from the production GPU, the bpy script that produced it, the settings and the GPU seconds. Pass the script's URL as scene_url to get the same result.

Settings

Blender warnings

• environment preset 'sunset' replaced the scene's world (HDRI lighting)

The script (bpy, runs as is)

ex19_terrain_displace.py. It builds the scene, the camera and the frame range; resolution, samples, denoising and the GPU are set by the service.

"""JANCTION Render example 19: a mountain terrain from a displaced grid, with water, at sunset (one still).

Reproduce: render_final(scene_url="https://render.janction.jp/samples/ex19_terrain_displace.py",
                        width=1920, height=1080, samples=128, environment="sunset")
A 200x200 grid displaced by a procedural Clouds texture through a Displace modifier; a flat plane for the water.
