How can I make a luminescent gas cloud, similar to the one shown in the picture below (labeled "Trapped Atoms")? Thank you.


Simple Sphere with Emission as a Volume would be sufficient. We will use for both methods mostly the same setup. Gradient Texture > Color Ramp > Emission shader.

Color Ramp will control color and smoothness. Emission > Strength... Strength.

Without Emission.


They will look like gas spheres and emission will not affect other meshes.


With Emission.


This ones will affect meshes with light.

  • $\begingroup$ Hi cgslav, I have tried using your method. However, when I increase the emission strength, the cloud goes back to being a solid sphere again. Do you know a method that works at all emission strength? Thank you. $\endgroup$ – user3886914 Oct 16 '18 at 23:15
  • $\begingroup$ @user3886914 than you will need to tweak color ramp to make it soft again. $\endgroup$ – cgslav Oct 17 '18 at 1:27
