d13 Posted January 10, 2018 Share Posted January 10, 2018 Hi Everyone! I'm working on a solar system model and am currently trying to create an accurate-ish simulation of Halley's Comet. The comet tail aways points away from then sun. So, I have a two part question for any experienced users out there: 1. How can I obtain the vector between 2 meshes (in this case Halley's Comet and the Sun)? 2. Which properties do I need to set in the ParticleSystem object to make the particles emit in the direction of that vector? Quote Link to comment Share on other sites More sharing options...
