Anyone have an idea of how to make popcorn fill up my screen using practices, or got some video that would help me out, thanks! I am trying right now, but they keep jumping up and down and not staying in place, how can I fix that at least, would help tons. Okay an update, I am getting there, but my popcorn right now has no collision, I checked on size deflect, but that's not it. Currently, I have 5000 emitters and it still won't fill up the whole box.

I are almost there!

If you want your background to be static, the important settings are:

  • a very high Number of particles
  • Frame Start = Frame End = 0
  • a very high Lifetime
  • emit the particles from the Volume of a cube, so that the density is even (this is important)
  • remove all Velocity from the particles
  • remove all Field Weights

enter image description here

For the collisions, emitting particles from the volume greatly reduce that problem: the distribution is more even and if you want you can set the Distribution (in the Source section) to Grid and play with the Random value

  • $\begingroup$ What I did what generate the popcorn using the particle system and then convert them to actual meshes, and use the rigid body to simulate the rest, I reduced the poly count greatly on em tho. $\endgroup$ – toshi Oct 25 '19 at 8:47
  • $\begingroup$ Why did you use a rigid body? do you want to make an animation? $\endgroup$ – Tareyes Oct 25 '19 at 8:52
  • $\begingroup$ Well yes, I need to fill like an empty box with popcorn and the camera is inside. $\endgroup$ – toshi Oct 25 '19 at 9:33
  • $\begingroup$ Ah, ok, you should edit your question though, because it seems you want a static image $\endgroup$ – Tareyes Oct 25 '19 at 10:19
