Barometric/Approximate Atmosphere, Clouds And Planet Shaders

Barometric Formula Based Volumetric Atmosphere, Volumetric/SSS/Translucency Based Cloud and Planet Shader:

Includes:

Atmosphere:

• Ultra precise, modular volumetric atmosphere shader based on Barometric-Formula

  

  • Modules include:
    • Rayleigh Scattering based on Barometric-Formula
    • Mie Scattering for fine particle simulation
    • Precise ozone absorption based on real life measurements
    • Spheric altitude calculation for regular planets
      • Custom altitude formulas easily supported (square planets?)
  • Use which ever modules suit your project

• Fast volumetric atmosphere shader based in exponential approximation

  

  • 90% of the result for up to 30% less render time
  • Includes Rayleigh scattering, ozone absorption and Mie scattering
  • Custom altitude formulas easily supported

Clouds:

• Ultra realistic, volumetric clouds using custom displacement to avoid intersection with planet sphere

  

  • Slowest rendering, with by far the best quality
  • Perfect for far away as well as extreme close up shots
• !! For true volumetric clouds please use a spherical mesh that has two spheres, one with the normals flipped to the inside, or the mesh provided by the blend file as it is needed for proper functioning of the shader!!

• Subsurface scattering based clouds with real displacement

  

  • Good compromise between performance and quality
  • Very usable for wide shots

• Translucency based clouds with real displacement

  

  • Lowest quality with the fastest render times
  • Still very useful for wide shots

Planet:

• Visually pleasing and easy to use earth shader

Made For Precision:

These shaders are made to achieve the highest precision possible with great versatility and photorealistic results. The pack also includes approximation of that precision in exchange for lower render times, while still providing far better quality than most other atmospheric shaders out there.

A Pro product meant for strong machines and the wish for no compromises!

!IMPORTANT!

This setup is very memory intensive to run (clouds, adaptive subdivision) and therefore won't runt on system with little VRAM. A GPU with at least 16 GB of memory is suggested.

Not using adaptive subdivision will drop the VRAM usage substantially.

Simple To Set Up:

Atmo Shader Setup

All you need to do to get up and running is to include the provided Blendfile as an Asset Library in the settings

Open the Asset Browser and start using all the parts of the bundle you want to use!

The Asset Library includes everything needed to just get started with the shader including the models, shader node groups and materials. Just drag and drop them wherever you need them.

!! For true volumetric clouds please use a spherical mesh that has two spheres, one with the normals flipped to the inside, or the mesh provided by the blend file as it is needed for proper functioning of the shader!!

Previously experienced precision problems at larger planet scales (1000 m and above) should be a thing of the past and the shaders are optimized for planets at a scale of over a 1000 m.
