🎯 What’s Included

Verlet Line (new in 4.1.0)

Create and simulate ropes, lines, cables, and more. Heathen’s Verlet Line tool supports full collision along the rope, pinning points to transforms (or vice versa), and “Force Transfer” pins to apply realistic physics forces between the rope and Rigidbodies — perfect for building swings, wrecking balls, cranes, flails, and more.

Verlet Transforms

Animate Unity Transform hierarchies, such as armature bones, using Verlet integration. Ideal for soft-body-like effects at low cost — great for hair, tails, jiggle, bushes, signs, flexible poles, and anything that needs fixed-length physics-driven motion.

🛠️ What You Can Do

• Animate signs, swings, tails, ropes, or antennae without animation clips.
• Add dynamic motion to hair, clothes, and accessories.
• Simulate reactive props and soft body-like behaviours.
• Easily apply directional or positional forces at runtime.
• Fine-tune per-node behaviour with animation curves based on node depth.
