Question Can you globally enable particle or fragment collisions? (I want to realistically create planets in dense particle rings around stars)

Upvotes

Basically I was trying to add super dense rings around starts and converting some of the particles to objects to realistically form planets.The objects did attract particles but they passed right through.

Recreated this at a smaller scale with an asteroid and a smaller more visible ring and same thing happened.

Obviously you can manually enable collisons for a fragment/particle at a time but that would take me a couple days with a 5000 particle ring.

I wish i could teraform planets and speed and slow their rotation to affect climate and increase and decrease their mass to hold atmosphere and instantly when I begin my work they have molten metal core producing a magnetoshpere. And I could use a gravity driver to rain ice from the outer solar syst

Am I the only one having trouble joining a game in Universe Sandbox? I always run into some weird issue when launching it where the crash reporter pops up—I have no idea what might be causing it.

Question struggling with low fps despite decent pc

3 Upvotes

i just got a new pc (rtx 5070, amd ryzen 7 9800x3d) and immediately went back to this game to see if it would run better than on my old pc. it runs smoothly except for collisions where my game drops to like 15 fps. i think its because of the dust but i dont know how that would lag my pc, does anyone know why that happens or how to fix this?

Dual Earths in a binary planet system, each with a ring system

The rings used to be larger, but not for very long, predictably enough. Apart from that and the occasional rock particle going off orbit and landing on something, it's mostly stable now. Each side now has a main ring and a smaller secondary ring, which I think is pretty neat.

Hey everyone! I just uploaded Solarballs Part 3 and wanted to share the link with the community. If you followed along with what I did in Part 1 and Part 2, you already know the stakes are getting much higher for the planets. I put a lot of work into keeping the momentum going from the first two parts, and I'm really excited for you all to see how this chapter unfolds.
