Volumetric nebula rendered with E-Cycles in Blender 2.82. You can spot a distinct change in style mid way through the video. After rendering the first 5 scenes I finally chose a soundtrack. The soundtrack was too good to cut short so I rendered 6 more experimental scenes to get to the end!
Soundtrack is called Limitless Potential by Joel Nielsen from the game Black Mesa. Listen and pick up an album here:
