BT - OptiCullingX: AAA-Level Occlusion Optimization System

Transform Your Game's Performance with Professional AAA Level Dynamic Culling Harness the power of data-oriented design and high-performance native code to manage thousands of objects with zero CPU overhead. BT-OptiCullingX delivers a production-ready visibility framework that replaces static baked data with a fully dynamic, raycast-based occlusion system. Engineered for high-fidelity PC titles and resource-constrained mobile VR projects alike.

Core Optimization Modules

Dynamic Occlusion - Raycast-Based Visibility

• Instant Occlusion: A dynamic system that requires no baking and works with moving occluders and targets.
• Temporal Stability: Advanced filters that confirm occlusion over multiple frames to eliminate visual flickering.
• Zero-Alloc Material Cache: Intelligently identifies transparent surfaces like glass to prevent incorrect culling without generating GC allocations.
• Adaptive Raycast Budget: Precisely control CPU usage with configurable ray-per-object and frame-budget settings.

Advanced Frustum - Jobs-Powered View Filtering

• Multi-Threaded Execution: Leverages the Unity Job System to process visibility checks off the main thread.
• Frustum Padding: Configurable safety margins to prevent shadow artifacts and pop-in at the screen edges.
• Screen Size Culling: Automatically discards objects that are technically in view but too small to contribute to the visual scene.

Intelligent Distance - Profile-Based Culling

• Size-Based Scaling: Automatically adjusts cull distances based on object volume—large landmarks stay visible while small debris culls quickly.
• Layer Overrides: Define specific visibility thresholds for different object categories like "Terrain," "Characters," or "Props".
• Smooth Fading: Seamless alpha transitions for renderers to eliminate harsh popping during movement.

Light & Shadow - Real-Time Performance Control

• Shadow Culling: Disables expensive shadow map calculations at distance while maintaining the light source visibility.
• Importance System: Prioritize key gameplay lights over decorative environment lights using a weighted priority system.
• Intensity Fading: Smoothly interpolates light intensity during culling transitions for high-end visual fidelity.

Production-Ready Features

Professional Editor Suite

• Unified Dashboard: A centralized control window with real-time telemetry and module management.
• Batch Setup Tool: Apply culling logic to thousands of objects instantly with advanced filtering options.
• Visual Debugging: Scene view gizmos and color-coded bounding boxes for immediate visibility verification.

Runtime Intelligence

• Burst-Compiled Core: Critical mathematical operations are compiled into highly optimized native machine code.
• Lazy Cleanup: Incremental registry management to prevent frame-rate stutters during object destruction.
• ICullable Interface: Flexible API to integrate custom AI, particles, or procedural systems into the culling pipeline.

Proven Performance Gains

• Significant Draw Call Reduction by disabling non-visible geometry and shadows.
• Minimized Main Thread Pressure by offloading calculations to worker threads.
• Optimized GPU Fill Rate through aggressive screen-size and distance filtering.
