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!

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?

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!

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

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

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?

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…

Great tutorials! What video card do you have?

Currently I have the GeForce 660 Ti and it’s probably the fastest part of my PC. My CPU is a Core 2 Duo @ 3GHz

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.

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

Awesome! Do we get to see the spaceship render at some point? 🙂

you guys are so anal
i just said that its common knowlege
i didnt say it a bad video
in fact i liked the video
i wish my subs were so defensive about me when i get haters

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

overlapping collision
if you break up an object with throusi and place a large object inside the broken up object you get a verry cool explosion too.

There is always someone somewhere who knows something that happen to be the same as someone else knows. In this case, I was not one of them, so I found this tutorial useful.

if you have used cinema 4d a significant ammount of time, its pretty basic knowlege that when you place one object inside another with dynamics on, you are asking it to do an impossible thing so it repells them at a great force, i not saying its a bad video, all im saying is that 80% of cinema 4d users know this stuff long ago since the early releases of c4d

@RiTutorials:
This is the Bullets engine, and not Cinema itself. You will find the same effect in other 3D apps who also use Bullets. I commented because I did not understand the purpose of your comment. Your statemet will apply to hundreds of tutors we come across, on the Internet. These tutors serve their purpose even if only 2% find them useful. And those who make them need our support! Myself I knew this effect already, from Carrara and C4D. Still I liked it and gave my kudos.
