Sticky Dynamics
In this tutorial I demonstrate a technique that allows you to create a sticky type effect with your dynamic simulations in Cinema4D.
By using the Force object in combination with Step Falloff you can create a setup where the objects stick together depending on the force applied.
Check out the tutorial below, or watch it on Vimeo.

I’d listen you go crazy on mograph for hours! You mastered it better than anyone else…
Great tips with key shortcuts also! Nobody’s teaching shortcuts, wich in my opinion are really important!
I tried out your technique and put everything into a metaball object, well the results are pretty amazing!!!
I had a few problems though: the animation doesn’t work well, not even when mograph caching the entire movement of the balls.
Also, in the viewport I get different animation frame from the ones in the picture viewer, like the cache has an offset somehow…
Also, unfortunately metaballs hdon’t have parameters enough to get a perfect tweak out of them…
Still pretty amazing though!
Please keep up the great work!
Tim,
I followed along with your demo here, pretty amusing and effective results. However, I did notice many imperfections in the collision models. Furthermore if all the spheres render perfect anyways, it makes no sense to give them anything but the lowest possible geometry as the viewport simply gets slower and slower. My solution was to copy off a version of the sphere, turn it into a fairly high resolution icosahedron, make that a polygon object, and then hide it and link it up as “Another Object” in the Collisions tab of the dynamics tag. Then you get accurate collisions, good renders, and you don’t have to deal with a lot of geometry, just a lot of calculations.
I’m sure you already know all about this, just felt it wasn’t important in the context of this demo. Cheers for the excellent work you do.

Interesting technique especially the tip on the formula effector is great. Also the tip from Julien with the Proxyobject for the simulation is a good one. But I wonder if it wouldn`t be the same to use a sphere, set the segments very low and activate “render perfect” under the sphere settings…
Hi everybody,
Thanks alot Tim for all your knowledge sharing.
I was watching this video, and thinking about the effect in the movie terminator… when the other robot was on the floor like a liquide, and transforms to a human shape… Since, during the explanations, you mentioned Metaballs… so I tried to test what I’ve learned, also using the inheritance effector, but what I found out is that the metaballs won’t work if you you set “Render Instances” actif… it must be normal, but is there a way to bypass this ? I am using around a 1000 clones of the sphere, with the sphere set to 3 segments/6cm radius, and the viewport is really slow, the metaballs editor subdivisions are at 22cm…also the distrubtion on the cloner is set to Volume…I used the figure, from the primitives menu….
Certainly this isn’t what was used for the movie at the time, some 3D with the help of morphing (Elastic Reality comes to mind :- ) Anyways, just trying this for the fun of it… and thanks again for all what you’re doing to help us !!

I’m wondering if this method would be a way to get dandelion seeds to blow off the stem? Like in this video: http://www.istockphoto.com/stock-video-6869315-dandelion-01-blow-on-blue-gradient.php?st=b35f4cc
You could trigger dynamics by using an effector to make them blow off the stem, set them to trigger at velocity peak and use an effector to move them very slightly. Add some wind and you should be good to go. You wouldn’t really need to use the sticky technique.
Hi,
I’m trying to create the magnet effect on iron particles, so far i’ve did tests with thinking particles,
could this tehnique be the key?
can’t really get the particles to stick into formations like the real iron particles do when touching them with a magnet,
any hint is highly appreciated,
Thanks

I love your work Tim!!
