Chonk Colliders - Utilities

🎮 Check out the live web demo here

🎁 Bundle Deal: This package is included in the Neko Legends - 3D & VFX Starter Bundle.

🧰 Features – Chonk Colliders for Unity

Chonk Colliders is a one-click collider generation tool for Unity, built for developers who need fast, optimized, and visually clear colliders—whether you're working on massive environments or chonky cats.

Chonk Colliders leverages the proven performance advantage of using multiple box colliders over a single mesh/convex one. With smart parameters and intuitive options, it generates efficient proxy colliders that you can fine-tune manually to suit your needs.

No more waiting for slow calculations or relying on heavy DLLs that break on WebGL or 

mobile—this utility gives you the best of both worlds: instant flexible generation, precise manual control, and all platform support.

⚡ Fast Generation, Full Control

• One-Click Generation
  Create colliders instantly with a single button click in the custom inspector.
• Iterative Workflow
  Tune parameters → regenerate → refine manually. Strike a balance between automation and precision.
• Top-to-Bottom Mode (2D logic)
  Enables a fast, slab-based algorithm for creating horizontal box colliders from top to bottom—ideal for objects without a lot of complex depth or holes.

📦 Collider Types & Physics Setup

• Collider Type Selection
  Choose from Box, Sphere, Capsule, or Convex Mesh colliders.
• Add Rigidbody (Optional)
  Supports full Rigidbody setup with toggleable Kinematic, Gravity options and auto mass calculation.

🧠 Optimization & Merging

• Optimize Colliders
  Smartly merges nearby colliders based on the mergeDistance threshold to reduce collider count.

📏 Scale & Precision Tuning

• Collider Scale Factor
  Scale colliders to fit tighter or looser around geometry.
• Reposition Colliders
  Ensure center alignment or let Unity automatically place colliders.
• Size Limits
  Set min/max bounds to avoid overly tiny or oversized collider boxes.

🧩 Advanced Mesh Handling

• Gap Filling
  Auto-adds extra colliders in uncovered regions to improve proxy coverage.
• Child Mesh Support
  Easily include or exclude child objects from the generation process.

🎨 Visual Debugging

• Color Fill Colliders
  Overlay color-coded collider visuals in-scene, customizable with alpha transparency.

🛠 Built-in Tools

• ✅ Generate Colliders – Quickly build based on current settings
• 🗑 Delete Colliders & Physics – Clean up your hierarchy in one click

🐾 Bonus Wooden Car and Robot models

🎵 Bonus Music

Royalty-free music included from video demo to enhance your demo scene atmosphere.

📦 Dependencies

To experience this asset as intended as shown in the video and web demos, you’ll need the following free assets from the Neko Legends collection:

✅ [Shared Assets URP (FREE)]

Contains core demo GUI, reusable scripts, and shared 3D models and textures across all Neko Legends assets.

✅ [Neko Legends - Anime Cel Shader (Optional)] is not required for this shader to work, but it is used in the demo scene as well as in Shared Assets URP. Without it, materials in both assets will appear pink, which would cause this asset submission to fail.
