How can you make a bunch of objects explode? I don't mean fracture, I just mean shoot off in random directions. I want to know how to do this for a rigid body simulation. So how can this be accomplished?

    $\begingroup$ @TARDISMaker ? I don't see how this is asking for a in-depth tutorial.. If any kind of tutorial is considered off-topic, then this site doesn't make any sense ;) $\endgroup$ – gandalf3 Apr 29 '15 at 1:44
  • $\begingroup$ Okay, I guess we just have different places where we draw the line. To me it still seems a bit too tutorial like for a question and answer site. I guess I'm more strict about it than I should be than. $\endgroup$ – TARDIS Maker Apr 29 '15 at 2:14

    $\begingroup$ if you ask me, explosions should be on topic either way, just cause they're so dang cool. $\endgroup$ – Scalia Apr 29 '15 at 3:44
  1. Add Active Rigid Body Physics to your cubes.
    (I created the cubes with 3 array modifiers applied, then separated By Loose Parts, and finally moved the origins to the geometry.)
  2. Add a force field in the middle of the stack of the cubes.
  3. Increase the strength of the force field.
  4. Press play or AltA and watch the explosion.

  • $\begingroup$ This is very useful, but I can't get the exact effect you had. You are using Blender 2.74, right? Strength = 900 didn't seem to cut it. $\endgroup$ – TheMinecraftMan757 Apr 29 '15 at 2:28
  • $\begingroup$ Never mind. I found a strength that will work. Thanks a lot! $\endgroup$ – TheMinecraftMan757 Apr 29 '15 at 2:36

    $\begingroup$ @TheMinecraftMan757 make sure you have applied the scale of the cubes. $\endgroup$ – PGmath May 1 '15 at 23:18
  • $\begingroup$ It works but I also tried to make an explosion with particle effects. The force field is messing with the particles so is there a way around this? $\endgroup$ – James Huang Mar 27 at 21:20
