Starfield Skydome to create beautiful night scenes at once
This is a Starfield Environment ready to use for Blender Cycles World. This World Setup uses both,a high resolution Image and a procedural Sky Texture to achieve a photorealistic Background as well as a good Global illumination. The Starfield Image Map contains more than 2.4 Million Stars of the visible universe! By simply adjusting one Value you will get either a light filled Skydome, or an overwhelming amount of stars that even shows the structure of the milky way. Scientific correct, High and Low Resolution Skydome
The Skydome comes with two preinstalled Sizes:
A high Resoution Texture Map with 163848192 Pixels, PNG Image,
and a low resolustion Texture Map with 81924096 Pixels, PNG Image.
Simple Node Setup
As shown in the Product Documentation, you can both tweak the appearance of the World Background, but also independent to this the Global illumination of the Scene. This gives you maximum control over the Scene. I recommend to adjust the Sky Texture first. Therefor you can set the Value 'Blend Stars into Sky' to Zero. After Setting the Sky Texture and its Lighting Strength,
Set 'Blend Stars into Sky' to 1. Then tweak everything of the appearance of the Stars. Finally, Set 'Blend Stars into Sky' to a value higher than 0.8.
