Shown above is a NASA photograph of the center of the Orion nebula taken from NASA's Hubble Space Telescope [left], alongside the image of another nebula, this one created entirely in Bryce 4 [right].

In this tutorial, We'll see how to make Bryce 4 a tool for creating scenes beyond a planetary system, particularly the gaseous nebulae that occupy deep space. All of the presets mentioned in this tutorial are included in Bryce 4.
