Inflated Objects using Geometry Nodes

Using Blender's geometry nodes you can create a bunch of inflatable balloons inside any mesh!

OMG LOVE IT! Thank you for sharing!

[@HakanYilmazAbstractizm]

Great tutorial! More please!

[@benyafezstudio]

Thank you so much, this is what I was looking for.

[@francoisvillemaire773]

Good stock! great explanation

[@esteban_ama]

great tutorial! Thanks!

[@chriskhaukha]

Thanks Robbie

[@SparkyandKai]

excellent video! easy to follow :)

[@jeffg4686]

neat technique. never even noticed the Pressure aspect of cloth physics. I guess it's just like a built in force field.

[@graphicdesignismypassion9915]

thank you so muchhhhh 💕💕

[@aungbwee7373]

Thank You Sir

[@XXsMosXX]

Dude, came here from your Instagram. Easy to follow, nicely explained. Keep it up!

[@RobbieTilton]

appreciate it mate!

[@sander-wit]

Great tutorial, thanks! To inflate the balloons a bit after the sim, I would use the displace modifier instead of the solidify modifier to avoid to creating an inner shell.
Also, to distribute the points within the volume without them intersecting, you can change the 'random' dropdown to 'poisson disk' instead of adding the merge by distrance. You can than set a minimum distance for each point.

[@RobbieTilton]

good suggestion re displace modifier!

[@nenikamou]

Great tutorial! How do you randomize the scale of the ico spheres? Yours seem to have different scales but mine are al the same size!

[@alexvith]

Hi Robbie! Another way you can do this without actually simulating anything is by using Geometry Proximity. Each particle would "sense" the closest particle to it and you can use the distance factor to deform the particles according to how close they are to the next one. This works because particles are scattered based on the Voronoi pattern.

[@benoitg.9571]

Could you develop? How can I use Geometry Proximity inside a point cloud with « itself » (the points arounds) ?

[@letomaneteo]

Is it possible to use nodes to control the rotation of individual instances on a curve in order to create, for example, an animation of cutting grass?

[@jmdenisme]

love it

[@RobbieTilton]

thanks jm!

[@areksztern]

The tutorial is GREAT, but how to replace colors with sample three textures.(Replace ColorRamp...on what node?)

[@IvanMax33]

This tutorial is about regular cloth inflating, geo nodes here are just for base spheres scattering , don't be baited.

[@DomenicoMontaruli]

why I can not find mesh to volume?

[@zubinator1]

Hi! I love this idea but I'm having some issues! I followed every step, but my particles just explode out of the collision shape right away. I turned the pressure down and then they do nothing, but once I turn the pressure to 130 they leave the collision field. I can see that theyre slightly colliding with eachother but I dont get how theyre leaving the mesh? I followed every step.

[@RobbieTilton]

you play with the tension parameter? try increasing it a little bit. depending on the scale of your meshes the parameters will always be different so my best advice is to play with both the pressure and tension. find where the pressure is enough to just make it explode (at the edge where it does nothign vs explode) and then add tension until it doesn't clip

[@user-gu9vf3cc4u]

Great job, but I have to say the first thing that comes to my mind is I can use this tech to create poop...

[@RobbieTilton]

lol

[@PeterHertel]

Haha I had the same thought. Make it brown and it'll look like intensities 😂

[@juanerro2323]

Hi! tks for the tutorial. Can't find 'distribute points in volume''. I just see the 'distribute points to faces'.

[@RobbieTilton]

which blender version are you on? IT was added on 3.4 and up

[@mickyr171]

Im currently trying to do this all within geometry nodes using simulation nodes and distance or ray tracing but cannot figure it out lol, got them to inflate and they do interact with each other but they seem to interact as a whole and only from the centers of the balloons, not sure what im doing wrong

[@mickyr171]

So finally figured out a method, posted a short clip to my alt account, pretty happy with how it turned out without a cloth sim and entirely in geometry nodes

doooope

thanks dorian :)

i dont find add torus on my screen :/

[@eclecticgamer5144]

Soooo... you're not actually using geometry nodes to inflate the objects... 🤦

[@RobbieTilton]

part of it is and part of it is cloth sim. geo nodes lets you easily apply the inner balloons to any mesh
