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

time.


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 planet surface does not react to light sources other than the main GeoSim sun

-Camera depth of field is not supported with GeoSim planets in the Cycles render engine

Most of these will likely be fixed in future updates!

*All future updates will be accessible to anyone who currently owns the product.



Changelog
1.1

  • 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.


1.2

  • 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.


1.3

  • Massive UI and documentation overhaul.

  • Support for terrain displacement and self shadowing

  • Clouds are much more photorealistic.

  • Various bug-fixes and optimizations.

  • Support for Blender 3.0.

  • Added "Color Separation" and "Ambient Light" sliders for better control of the atmosphere.

  • Added a separate downloadable file called "Textures" containing 2k, 4k, 8k, and 16k earth textures, courtesy of NASA
