Stands out in the superhive library because it builds the slime with Geometry Nodes and keeps it linked to the source objects, so it follows them when they are moved, rotated or scaled.
Made in Blender 3.1 by Ignacio Matey, the Procedural Slime Add-On creates procedural slime between two objects, with a wide set of controllable parameters. The slime is generated as an object carrying a Geometry Node modifier, and if you move, rotate or scale the connected objects, the slime follows them.
Getting started means installing the zip file, then opening the add-on panel in the viewport sidebar with the N key. On first use you click Append, which brings the Geometry Nodes setup the add-on needs into your blend file. After that, select the two objects you want to link and click create slime. The interface was inspired by the GeoCables add-on by Amandeep.
Parameters cover the look of the slime: density sets the number of tentacles, viscosity governs how much it hangs under gravity, radius adjusts tentacle thickness, and seed changes the random arrangement. Profile and length curve control subdivisions, while slime in contact defines how far it spreads over contact regions. A default material ships with the add-on and can be swapped for your own.
Procedural Slime Add-On is best for blender artists creating procedural slime stretched between two objects.
Procedural Slime Add-On is completely free to download and use.
The Procedural Slime Add-On installs from its zip file like any Blender add-on. Once enabled, the panel appears in the viewport sidebar, which you open by pressing the N key. The first time you use it, click Append so the Geometry Nodes setup the add-on relies on gets appended into your blend file. From there you select the two objects you want slime between and click create slime, and a slime object is generated with a Geometry Node modifier attached.
The Procedural Slime Add-On creates the slime as its own object carrying a Geometry Node modifier. Once it exists between your two chosen objects, moving, rotating or scaling those objects makes the slime follow them, so you can reposition parts of your scene without rebuilding the effect. The result is driven by parameters rather than fixed geometry, and the seed value lets you change the random layout of the tentacles whenever you want a different look.
The Procedural Slime Add-On comes with a default material for the slime, and you can replace it with your own materials at any time. Alongside the material, you shape the look through parameters such as density for the number of tentacles, viscosity for how much the slime hangs under gravity, radius for tentacle thickness, and slime in contact for how far the slime spreads over the regions where it meets the objects.
The Procedural Slime Add-On is listed as free in this catalog. For current licensing terms, download details and any updates, check the developer's page. The add-on was made by Ignacio Matey in Blender 3.1 and comes with a YouTube tutorial that covers the same steps as the written instructions, so you can follow along while setting it up and learning how each parameter affects the slime.
