Geosim V1.2 | Photorealistic Planets (Eevee / Cycles)

by Alex R Heskett in Scripts and Addons

In order for me to recieve the same profit while still donating 20% to the Blender Foundation, this version is $6 more expensive than the GeoSim product on my Gumroad. If you cannot afford this version, you can access the cheaper version here.

What is GeoSim?

GeoSim is an add-on which allows the creation of photorealistic, realtime, customizable planets in a matter of seconds. Combined with a robust and easy to use shader nodegroup, GeoSim is a must-have for any 3D artist looking to create space/sci-fi scenes.

  - Physically Based Volumetric Rendering

Using a multitude of advanced techniques, GeoSim can create photorealistic planetary atmospheres at a much higher quality and speed than Cycles or Eevee. Attributes such as density, thickness, and color can all be controlled with in the GeoSim shader.

  - Image-based Clouds

In order to add an extra layer of realism, GeoSim includes real-time, shadow-casting clouds. Just plug in your image/procedural texture and the shader will automatically convert it into semi-3D, volumetric clouds.

  - Full Texture Support

GeoSim comes fully equipped to handle all required textures, including albedo, specular, roughness, normal, and emission. All image textures can be accessed easily through
a separate nodegroup, allowing them to be modified at any

For instruction on using the addon, see the documentation section.

Current Limitations/Things to note
-The planet surface does not react to light sources other than the main GeoSim sun

-The planet surface cannot be deformed or interacted with, aside from basic transformations

-Adding keyframes to the values in the GeoSim nodegroup will slow down playback performance considerably

-The materials applied to the GeoSim planets cannot be renamed (doing so will break some things)

Most of these will likely be fixed in future updates!
*All future updates will be accessible to anyone who currently owns the product.


  • New "Surface" section in GeoSim Nodegroup.
  • Added the ability to disable emission maps on areas of the planet that are in daylight, for use with city lights textures.
  • Normal map strength is now controlled outside of the shader.


  • 33% decrease in render times due to optimizations and bugfixes.
  • The camera may now fly inside of the atmosphere.
  • Normal mapping and cloud coloring bugs fixed.
  • Support for Blender 3.0.
