JiggleGen

Create a vertex group, paint the areas that you want to make jiggly, choose a preset and hit generate. Don't like it? Just overwrite it! Everything can now become a wobble pudding. JiggleGen comes with a intuitive workflow, that allows you make quick adjustments to archive the perfect results for your animation.

• Cloth & Collision Mesh from Vertex Groups: Quickly generate simulation-ready cloth and collision geometry from any vertex group.

• Automatic Target Attachment: Attaches the target mesh to the generated cloth via a Surface Deform modifier, bound automatically with an automatic retry for reliability.

• Editable Pre-Generation Cloth Settings: Adjust cloth simulation parameters before mesh generation for total control and flexibility.

• Integrated Preset Library: Save, load, and freely manage cloth setups using Blender's own native preset system. Including presets you made outside JiggleGen, with no artificial restrictions on what can be deleted.

• Configurable Preset Location: Point JiggleGen at a custom preset folder if you don't want the default shared Blender directory, with a one-click button to open it.

• Structured, Customizable Naming: Auto-generates meaningful names for all objects and modifiers based on origin mesh, vertex group, and preset. With the prefixes and collection name fully editable in Preferences.

Simulation Backends

• Classic Cloth Modifier: The proven default, unchanged and fully supported.

• Geometry Nodes Cloth (Experimental): Optionally simulate with Blender 5.2+'s "Cloth Dynamics" node group instead, chosen per body region. With its own dedicated settings panel and full preset support.

Hair Support (Experimental)

• Hair Cage: Builds a jiggle-ready proxy mesh directly from hair strand curves, simulates it through the same Cloth pipeline, and drives your original hair from the result automatically.

• Optional Modifiers for Simulation Cages

• Offset: Raises or lowers the influence of one VertexGroup/Pingroup

• Threshold: Controlls which influence value is included.

• Decimate Modifier: Automatically reduce vertex count for performance.

• Smooth Modifier: Add surface smoothing for cleaner cloth deformation.

• Parent to Target: Generated cloth or collision meshes can automatically be parented to the target object.

Compact Utility Panel with Smart Shortcuts

• Toggle Jiggle Visibility (Viewport / Render)

• Bake All Dynamics / Clear Bakes

• Copy or Extract Cloth Settings to/from the Active Object

• Toggle Armature Pose/Rest

• Add Curve Tools (hair strand thinning, ahead of Hair Cage generation)

Batch & Automation Features

• Batch Cloth & Collision Generation: Process multiple objects in a single batch. Perfect for characters with multiple dynamic areas.

• Per-Vertex-Group Preset Application: Assign unique cloth presets to each selected vertex group for full customization.

• Batch Management Panel: Review, modify, or regenerate every component of your model through an organized batch queue, with copy/paste/copy-to-all for settings across vertex groups.

• Smart Collision Exclusion: Collision is its own task per target, with an adjustable margin that can grow or shrink the excluded region.

• Import Legacy Batch (v1.1): Recovers batch setups from files last saved with JiggleGen 1.1.0, including previously-generated proxies, so upgrading doesn't mean starting over.

• Batch Entry Jobs: Transfer, export, and import batch configurations between objects and files.

Reliability & Reporting

• Detailed Generation Report: Every run reports exactly what succeeded, what was skipped, and why.

• Non-Destructive Targets: Original mesh data, shape keys, materials, UVs, and vertex-group weights are never altered.

• Failure Isolation: One failing region never stops the rest of the batch.

• State Preservation: Your active object, selection, mode, and current frame are restored after Generate or Remove Jiggle.

What is JiggleGen?
JiggleGen is a Blender add-on that automates the creation of cloth-based proxy meshes for jiggle and tissue simulations. It streamlines the setup process by generating simplified cages driven by vertex groups, making secondary motion effects faster and easier to manage.

Who is JiggleGen for?
JiggleGen is intended for experienced Blender users who are already familiar with the basics of cloth simulation and modifiers such as Surface Deform.

Will using JiggleGen slow down my system?
JiggleGen uses low-quality cloth modifiers to reduce calculation load. However, performance still depends on your system’s power and the complexity of the generated geometry.

How do I define the area that should jiggle?
You can mask the simulation area using a Vertex Group on the target object. JiggleGen uses this group to decide which parts of the mesh will move.

Do I need a specific topology for JiggleGen to work?
Yes. The target object should be low-resolution, one-sided (no thickness), have outward-facing normals, and contain no separate geometry islands.

Is JiggleGen only for characters?
No. While it’s commonly used for character tissue and jiggle effects, you can use JiggleGen for any object where you need simplified secondary motion.

Can I still use Subdivision or other modifiers?
Yes, you can use modifiers like Subdivision on your original mesh. Keep in mind that the ProxyMesh is stripped of modifiers except for the Armature.
