The aim of this post is to create a realistic environment sunset scene with believable clouds and atmosphere.
* To Create a Realistic Cloud and atmosphere exactly like the cover image, copy our render camera position to your project and follow the steps
Position = -34 84 -818
Rotation= 15 20 0
1. Create a Terrain
First, open the Terragen, We use Terragen 4.6.31
No need to add a Terrain node in the Graph, Just change the default value.
Double-click on Fractal terrain 01 and change these values to have a better Terrain shape.
Feature scale = 5000
Lead-in scale = 110000
Smallest scale = 0.1
Noise octaves = 22
Set Seed to 61062 if you want the same Terrain look as ours and change the camera position to find your best position.
Then double-click on Fractal wrap shader 01 and change these values
Scale = 2000
Wrap amount = 1
Variation = 1.5
Roughness = 1
Seed = 0
2. Atmosphere
For faster previews of your scene, enable RTP (ray-trace preview)
Then go to the Main tab and change these values
Haze density = 2
Haze horizon colour = 0.3
Bluesky density = 8
Bluesky horizon colour = 0.5
Bluesky additive = 0
Redsky decay = 0
Then go to the Lighting tab and set Haze sun glow amount to 2 and Haze sun glow power to 1.5
Now for a better atmosphere look, go to the Tweaks tab and change values
Ambient = 0.2
Fake dark power = 0.5
Fake dark sharpness = 10
Then click on the blue density colour icon and set Red to 99, Green to 161, and Blue to 234
Redsky decay colour = 0.88
Ozone factor = 0.75
It's time to add a cloud!
3. Cloud
In the Atmosphere tab, Click on Add Cloud Layer and select Mid-level : Altocumulus Castellanus, Large
Now change these values to have a better cloud look
First change Model to TG 3.9.04 Then set Cloud base altitude to 7000 and Cloud depth to 12000, now we have a high level and thicker cloud.
Now we need to add ground haze, so add Low-level: Generic in your Cloud Layer.
In Main Tab Changes
Cloud altitude to 198, Cloud depth to 400, set center to 2100, 190, 10000, Radius set to 10000, and Edge sharpness to 0.2 to have a softer cloud
Then in the Tweak Tab, increase the Ambient to 0.35 to have a lighter haze
Now we need to change the Pattern shape to have a better cloud looks
So click on Pattern then in the opened window set these parameters
Feature scale = 20
Lead-in scale = 4700
Smallest scale = 60
Noise octaves = 8
After that in the Density Tab increase the Coverage adjust to 0.15 to have more haze and set the Roughness to 2.5
Change Noise flavour to Perlin ridges in The Next tab
In the Wraping Tab set the Lead-in wrap amount to 3
You can change the Seed to have a better look, here we use 50309 for the seed value
4. Lighting
After finishing the cloud system its time to set a sun direction and create a beautifulOnce the cloud system is complete, it's time to set the sun's direction and create a beautiful sunset
In the Lighting Tab select Sunlight 01 and change Heading to 41, Elevation to 10, and Strength to 7
* Notice that values depend on your camera position
5. Render
Rendering is the last step to get a high-quality and clean image
Go to the Renderers tab, select the Quality tab then
Micropoly detail = 0.8 (better terrain quality)
Anti-aliasing = 7
To clean up your render, click on Edit Sampling and set the First sampling level to 1/4 and the Pixel noise threshold to 0.02
It's Done!
