I am trying to set up a simple space like gravity particle system for animation, but I have no idea how to make a tail on a particle to make it look like the way I want (Including the gradient) I basically have the particle system ready, but I just don't know how to make the tail. Any help would be appreciated, Thanks!

This is the example

For the particles:

  1. Start with a sphere
  2. move one vertex far away using proportional editing so that neighbor vertices are also stretched proportionally enter image description here
  3. to create the cloud of particles, use 2 array modifiers to create a matrix, apply the modifiers and separate by loose parts enter image description here enter image description here
  4. use proportional editing with Random and smooth fall off in order to arrange the particles. Alternatively, use Randomize Tranform. enter image description here
  5. create a gradient based shader, use Color Ramps to control color, emission and transparency fall offs (don't forget to turn Alpha Blend mode for transparency to work)

enter image description here

For the background:

Create a world shader based on spherical or linear gradient. Use the Vector Mapping scale, position and rotations to control gradient position in the sky.

For animation: Here is the same object used in a particle system (added plane emitter and moved camera around):

  • $\begingroup$ I see this is made for a still image, but will I be able to make this as a particle system? I know how to, but I've had issues with mapping material node and particle systems when the particle moves. I am trying to make an animation with it $\endgroup$

  • $\begingroup$ Nothing prevent you form using this comet object in a particle system... $\endgroup$

  • $\begingroup$ I added a screenshot of the same scene but using a particle system instead of Array modifier $\endgroup$

  • $\begingroup$ Ok, I'll give this a try, I was on the road for the past day getting home safe, Thanks $\endgroup$
