Realistic Atmosphere

Realistic Atmosphere

Physically-accurate planetary atmosphere material.

NOTE: Unreal Engine 4.24 was released with the new Sky Atmosphere component. If you are using Unreal Engine 4.24 or later and considering using this asset you may want to consider using the new engine feature instead!


*****

Physically-accurate planetary atmosphere material intended for use by game developers, filmmakers and other artists. It is powerful, flexible, efficient and easy to use. Key features are:


Realism

The material simulates the behavior of sunlight in the atmosphere. It accurately reproduces real-world phenomena such as scattering and absorption which are responsible for the blue color of the sky and the red color of sunset and sunrise.


Real-time editing

No need to create any special assets. When you change parameters on the atmosphere blueprint you immediately see the result.


Flexibility

You are not constrained to only create Earth-like atmospheres. You have full control over scattering and absorption parameters. By customizing them you can achieve more alien or stylized look.


Surface and space view

The material supports both space and surface views with seamless transition between them.


Dynamic lighting support

Lighting parameters can be controlled in real-time using Blueprint Properties which allows creating dynamic solar systems.


Quality settings

Trade accuracy for performance or vice versa. Three quality options are available: High, Medium and Low.

Limitations


Certain limitations currently exist:


No documentation

Unfortunately due to lack of time I am unable to write proper documentation. You can always email me if you have questions though.


No custom material support

It is currently impossible to use this effect with custom planet surface materials.


No interaction with objects

Atmosphere effect cannot be applied to other objects (unless you create and apply a custom material with atmosphere support to them)


No interaction with Unreal lighting system

All materials are Unlit so Unreal Engine lights do not affect them in any way.
