I would like to create something that is basically what array modifier does, but with a tiny bit of randomization (of both location and rotation). The particle system would be otherwise fine except that it is too random. I couldn't find a way to make the particles mostly organized with a little bit of randomness.

I found a really old patch to Blender introducing exactly what I wanted, but apparently it was never accepted: https://developer.blender.org/T26662.

EDIT: I used the method suggested by Faceb Faceb below to get the following result:enter image description here

The result is fine, but in this method I have to apply the array modifier before randomization which makes it more difficult to e.g. change individual parts of the array later (if I wanted to, for instance, fiddle with the shape or looks of the bricks in the picture above). If there is a way to achieve this result using the particle system, I'm interested.

    $\begingroup$ I think it would be helpful to explain and illustrate what type of randomisation you need and how far you got with using a particle system for this as I think a particle system is what most people will recommend. $\endgroup$ Feb 6, 2017 at 15:40
  • $\begingroup$ maybe apply the array modifier, separate loose parts, then origin to center of mass and then manipulate the center points with random falloff? $\endgroup$ Feb 6, 2017 at 16:07

    $\begingroup$ Not possible. Use animation nodes addon: youtu.be/M8x0YMbixC0 $\endgroup$

  • $\begingroup$ It is impossible with the current Array modifier alone. It might be possible using Duplifaces and applying them, or using a particle system instead. $\endgroup$ Feb 6, 2017 at 18:35
  • $\begingroup$ I created a quick example showing what I want to achieve using the method suggested by Faceb Faceb: imgur.com/7dPo7dM . This method works fine, but it is not very optimal because I have to apply the array modifiers before randomization. $\endgroup$

Result with Particle System

enter image description here


  • Create an Object (Cube) and bring it in the desired shape.
  • Create a Plane, subdivide it in Edit Mode (F6 for adjusting the number of cuts easily).
  • Add a Particle System to the Plane.

Setting up the Particle System

  1. In the Physics Dropdown choose No.
  2. In Render Dropdown choose Object and pick your "brick" you have created.

    enter image description here

  1. In the Emission Dropdown choose:

    • Emit from Faces
    • Grid
    • Enable Hexagonal Grid

    enter image description here

  1. Play around with the Resolution value in the Emission Dropdown and scale S your Plane along one Axis until you have a nice Pattern.

    enter image description here

  1. Randomize:

    • In the Emission Dropdown you can add a random Offset to the Grid locations
    • Enable the Rotation Dropdown and randomize softly the Particle Orientation

    enter image description here

    $\begingroup$ With version 2.79 I had to include the following step within: Setting up the Particle System 2.1 Enable unborn and died in the Render dropdown. $\endgroup$ Nov 17, 2018 at 2:37
