Small collection of VFX I did for the game 'Echoes of Empire' a couple of years ago. The idea was to create miniature version of these celestial bodies. Like if they were captured into a relic for an all might collectionist.
Most of the effects were achieved using unity vfx volumetric system nodes and illumination.
I only did the particles, vfx and illumination. 3D model and texturing was made by the incredible team at GameCoder Studios.
Nebula.
Black hole. This one was the most difficult because of the curved lines along the model.
Twin star.
White Dwarf.
