Using Blender's geometry nodes you can create a bunch of inflatable balloons inside any mesh! Patreon: / robbietilton Twitter: / robbietilton Instagram: / robbie.tilton Discord: / discord #blender #3D #geonodes
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.
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.
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
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.
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
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 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-phO2ws4WjnU.htmlsi=ZYKKUXmsAaYK_t1K
