BT-OptiCollider X: Ultimate Collider & Physics Optimization Tool

Transform Your Game's Physics Performance with BT-OptiCollider X

Are complex mesh colliders and heavy physics calculations bottlenecking your frame rate? BT-OptiCollider X is a comprehensive, professional-grade physics optimization suite designed to eliminate performance drops, streamline your workflow, and maximize stability across all platforms.

🎯 Core Optimization Systems

Smart Mesh Simplification & Optimizer

• Grid-Based Decimation: Aggressively reduce MeshCollider polycounts with custom vertex clustering algorithms (No external DLLs required).
• Intelligent Welding: Automatically merge duplicate vertices to save memory and physics cooking time.
• Hierarchy Merging: Combine complex child meshes into single, ultra-performant colliders.
• LOD-Aware Generation: Smartly restricts collider generation to LOD0, stripping unnecessary physics data from distant objects.

Physics Budget Analyzer

• Scene-Wide Scanning: Instantly detect performance killers in your active scene.
• Cost Scoring: Automatically flags expensive Concave meshes, high-poly offenders, and heavy Rigidbody interactions.
• Actionable Reports: Get a clear, color-coded health rating and estimated MS budget for your physics scene.

Runtime Animated Collider

• SkinnedMesh Sync: Keep colliders perfectly synced with animated characters and deformed meshes at runtime.
• Performance Throttling: Clamp bake rates to Target Hz, update every N-frames, or pause entirely when off-screen.
• Smart BlendShape Tracking: Only recalculates physics when necessary facial or morph targets change.

Advanced Compound Editor & Scene Tools

• SceneView Overlay: Edit and manage complex Compound Colliders directly in the SceneView with custom UI Toolkit overlays.
• Visual Handles: Intuitive drag-and-snap handles for Box, Sphere, and Capsule primitives.
• Auto-Fit Primitives: One-click fitting of primitive colliders precisely to renderer bounds.

🚀 Production-Ready Features

Quick Action Batch Tools

• Mass Replace: Instantly convert heavy MeshColliders to lightweight Boxes or Spheres across entire hierarchies.
• 1-Click Management: Add, remove, enable, disable, or set triggers for hundreds of colliders instantly.
• Copy/Paste Architecture: Transfer complex collider configurations between GameObjects with a single click.

Gizmo & Heatmap Visualizer

• Performance Heatmap: Visually identify poly-heavy colliders in the SceneView (Green = Optimized, Red = Heavy).
• X-Ray Mode: Inspect your physics world through geometry with color-coded collider types and dimension labels.

Safety & Workflow

• Zero-Risk Architecture: Fully integrated with Unity's native Undo/Redo system.
• Preset Management: Built-in profiles (High Quality, Balanced, Vehicles, Static Environment) plus custom save slots.
• Zero External Dependencies: 100% pure Unity C# API, keeping your project clean and safe.

📊 Proven Performance Gains
