The plugin allows access to a material that offers a multitude of parameters to adjust and create a variety of unique and realistic atmospheres. All atmospheres are calculated by considering the sun’s position, the planet’s position, and the point of view to allow the realistic rendering of the atmosphere. If the relationship between those influence factors and the atmosphere changes, it updates automatically.  

Based on different material instances for each atmosphere, it is possible to render multiple different-looking atmospheres simultaneously.
