Soft bodies help/tips/tutorials

Recommended Posts

Hey guys/gals!

 

Been trying to find a good tutorial or tips on how to use soft bodies in houdini but with no real success.

 

What I wanna do is quite simple but not sure where to start.

I wanna copy a bunch of sphere and they just fall and bounce around.

 

Basically this 

 

 

So if anyone got any good tips or a tutorial on how to do that I would be very happy!

 

Thanks!

Hi,

also check this tutorial.
As described in tutorial, you can use also wire solver for soft bodys. It should be faster but you may not get volume preservation (not 100 percent sure).

Alse I have seen great example here on forums which uses bullet solver and constraints.

Awesome! This cleared a lot up!

Im still struggling with this.
 
So what I figured out so far is that you can't just copy a bunch of spheres and then use a tissue object, that will just make the whole thing to one object.
Been trying to find a way to do this and I check the files from the post that Juraj posted and they're all good but none what I saw used FEM.
 
This is what I got and its clearly not working

Not sure if this is hard to do or if its just me.

Any help is appreciated :)

 

Thanks!

I don´t know if there is anything like a fracture object for FEM but you can add them via a sop solver over time  maybe ? I did not try that yet its just a idea!

Okay tried that haha not really working but maybe the grain solver is an option ! It does pretty good volume preservation and is fairly easy to setup ! 

Also with multiple objects !

for something as simple as spheres you don't really have to use embedding

copy tetrahedralized sphere, then sim with FEM and extract tetrasurface after sim
