Replicating a Specific Simulation

#1

Hi there,

I’m looking to replicate the simulation used in this video.

Video

Basically, I’m trying to recreate the fibrous effect that occurs after the tear.
If anyone has any insight to how this can be achieved or what type of simulation was used (nCloth, nParticles, etc.) that would be great.

Thanks in advance.

You could try a few methods here - http://forums.cgsociety.org/showthread.php?f=86&t=1097888&page=2&pp=20

While it may not give you exactly what you want, it may work depending on what your final renders need to look like.

Thanks Howard this effect would be great to add fibrous material after the break has occurred.

We dug around a few forums and someone at Simply Maya showed us this video and tutorial:

I think this combined with the effect you posted would get the job done quite well.
Your thoughts?

Should do, give it a go! :wink:

So I hit a pitfall.

I got the simulation to move and tear in a manner close to how I want it to. The issue though is that the particles are connected in between two plains. In order to get the particles to stick to the plains, I upped the stickiness attribute on both plains and the particles to 2.

Now when I play the simulation the particles snap back, hit the plains and become stuck to the plains. I quickly realised this is not the best way to anchor the particles. Can anyone think of a way to anchor them? I know with nCloth you can use “cv’s” but as far as I know you can’t use “cv’s” with particles.

Many thanks!

You should be able to do it all with constraints. Constrain the ends to the planes, but the trick is to also split the ‘tendon’ in the middle and also constrain those ends together.

Then you can control the glue strength to break it whenever you want and whatever shape you want.

Hey howard, here’s an update on the tear animation.

Working on getting the tear to happen towards the middle but I think I can figure that out.

Thanks for all your help! ^^
