Soft Body Painter is a powerful yet easy-to-use Blender addon that allows you to paint soft body simulation areas directly onto your mesh!

Key Features:

🎨 Paint-Based Simulation Zones: Just select your object and paint the areas you want to simulate. Fast, intuitive, and visual.
⚙️ Full Soft Body Settings Panel: Control stiffness, bending stiffness, damping, push/pull forces, and more from one clean interface.
🔗 Collision Options: Enable self-collision, face collision, and edge collision for advanced interactions.
🧷 Anchor Points with Weld: Easily lock specific parts of your mesh in place using the “Weld Points to the Original” function.
🔁 Non-Destructive Workflow: Keep your original object untouched while applying soft body physics on duplicates.

Soft Body Settings Overview

Vertex Group: The name of the group controlling the simulation area (usually “edges”).
Follow Original Object: Blends the soft body mesh’s motion with the original mesh for smoother results.
Stiffness: Controls how rigid the soft body is.
Bending Stiffness: Affects how easily the mesh bends.
Damping: Reduces wobble over time.
Pull / Push: Fine-tune how the simulation expands or contracts during motion.
Use Self Collision: Prevents the soft body from intersecting with itself.
Face/Edge Collision: Enables surface-level or edge-specific collision detection.
Weld Points to the Original: Anchors parts of the mesh to stay fixed during simulation.
