    Engine Plugin
    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.





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.
