A brief hybrid simulation/animation test.
baukepost Glad to hear that! To start, I turned the world gravity down to 0, made a flat ring mesh and positioned it around the sphere. Then I made a particle system on the ring that emits all particles at frame 1. To make them spin, I added a vortex field in the center of the sphere.
I would just like to say that I really admire your work and I really enjoy your tutorials! How did you make the astroids fly around the planet? I have no clue how you did that.
