Star cluster nebula simulation 3D model

This blender models contains all the elements that simulate a Star cluster and Nebula formation from a supernova core. The ColorRamp in the Material, based on the Density of the gas, can be changed from its rainbow of colors to any other variation so that you can have more than one in a scene. Adjusting the simulation times or Applying Modifiers can freeze static states or alternate dynamic effects.

The Nebula Cloud is a gas simulation with Goemetry and Inflow nodes and a carefully placed Collision envelope sphere and push-out and expansion limit forces to limit the expansion.

The Star Cluster contains two elements Several lights at expanding cluster positions are simulated as Particle System clusters, as are emission objects that reduce the lights required to meet Eevee light limitations. A light from behind mode is also included, that can follow any selected Camera position.

Both Eevee and Cycles rendering are supported, and the model is memory efficient.
