Blob Fusion

Blob Fusion is Blender extension organic and hard-surface meshes creation. It can be thought as mix of ZSpheres with Metaballs/SDFs, combining best of both worlds.

Latest version 1.6.x (extension) is for Blender 4.2+ only.

Capsules Blobs | Capsules + Sphere Blobs | Final posed character

Features/Functionality:

• Supported primitives: Sphere, Round Capsule, Cube, Torus, Mesh and Cylinder Blobs
• Auto-generated hierarchy of objects (rig like), when adding new Blobs
• Colorization of Blobs (introduced in Blob Fusion 1.6.3)
• SDF is converted to mesh in real time (no need for time-consuming meshing first). You can render what you see directly from 3d view.
• Smooth Blobs blending control [Alt+B]
• Subtract and Union modes [-] key to toggle,
• Simple workflow: Extrude, Subdivide, Connect and Duplicate is all you need to model
• Library of Blobs Presets (humanoid and animals)
• One click Armature generation
• Ability to deform Blob domains with Blender modifiers or instance them with Collection Instancing
