Exploding Things with MoGraph in Cinema 4D

This Five Minute Tip for Cinema 4D shows us how to use the Fracture object (MoGraph) and an Attractor force object to make things explode.

I stumbled upon this technique while stress testing the abilities of the MoGraph Fracture object, and it seems that it’s a great tool for blowing objects apart. The core of the technique hinges on using the self collisions to upset the geometry and kick off the initial repulsion. Once that’s taken care of, we can use a particle attractor (with a negative value) to push the pieces in the desired direction.

Let me know what you think. You should leave a comment and share your thoughts!

  1. Hello, I have the same procedure as described in the tutorial, when I work with normal objects is synonymous everything, only I use my created parts (HD engine) nothing happens. What can be the cause?

  2. Jamie,

    Been trying to figure this out now for some time and I feel like the answer is obvious. It I figure I would ask on this thread. Do you know if it’s possible to restrict the objects being affected by a collision
    in a Voroni fracture to a specific area? The only way so far I have figured is tweaking the dynamic threshold on the rigid body tag associated with that fracture. I’m trying to effectively blow up a side of a building structure but only have a specific area active to the explosion. Thanks!

  3. Is there a way to add an image texture to an object that is broken? Weird
    things happen to that texture….

  4. Good stuff! I never would have thought to use the attractor like that. Experimentation rocks! Thanks for this tip and the examples!

  5. Am I right in thinking that you don’t need a fracture object to do this? can’t you just put a dynamics tag on a null object?

  6. Trying to apply the same principal to a lightcycle model i made in a moving animation… Thing is when I set the lightcycle to rigid body its loses it’s spline movement… Not sure why this happening maybe someone can help me… I want the lightcycle to explode into cubes as they did in tron just not sure of the exact mograph settings to achieve the desired effect… Im in the right direction but not quite there yet…

  7. Great tutorials! What video card do you have?

  8. Yah. It is pretty basic knowledge and you probably did know about this a ‘looong’ time ago but you failed to find a way to use the effect creatively whereas Jamie did.

    So you do free downloads, huh? You get paid each time a file is snatched, don’t you? Must burn that people like Jamie put up way better material here. Jealous cunt.

  9. great tut. really liking all of your videos!

  10. Love this tutorial. Exactly what I need to blow up my spaceship. thanks a ton!

  11. Wow… that’s veeery impressive RiTutorials! You’re da man, really!

    And thanks to Jamie for keeping sharing even when faced with stupid comments =)

  12. Which part? Overlapping collision distance? Or the negative value in the Attractor? Thanks for watching though.

  13. Gr8 vid man! I`ve been following your channel for sometime and learned a lot! Thx for this! Also C4D never fails to amaze me! Rock on!
