I have a mesh with a hair particle system, with mesh objects as hair particles. As you can see in the image below, some of the objects intersect with eachother.

enter image description here

I would like to set a minimum distance between the hair particles so they don't intersect anymore, but I can't find any way to achieve this.

    I have tried to do this before, and I don't think it is possible. Would love to have this feature, though, because there are so many potential applications! – JakeD Nov 30 '16 at 12:28
  • If you are making water droplets, I would try using meta balls for the particles. I don't know if it will work, but, it would be good to try it. – 10 Replies Nov 30 '16 at 18:34
  • It's not for droplets. I want to place trees on a map without them intersecting eachother – Ezra Nov 30 '16 at 20:55

  • @lemon definitely related, but a different question. – Ezra Dec 01 '16 at 12:33
  • i had a similar problem a while ago, didn't find any solution nor did I get any suggestions on how to solve/work around this. See my question here: http://blender.stackexchange.com/questions/60587/particle-emitter-is-intersecting-bounding-boxfaces.

    Seems like a lot of people wants this option but nobody knows how to solve this issue.

After researching a bit further, it looks like this is not a built-in feature for Blender. Although there are some workarounds to sort of achieve the effect that have been mentioned in the comments, the solution seems to be an add-on:

Here is a quick GIF of me doing particle collision with the add-on (I am on a Mac, so I am using an older version):
