SuraFix Runtime Optimizer

SuraFix Runtime Optimizer
Take back control of your frame time.
Stop hand-tuning LOD distances for hours. Add a level, set a distance, done — cross-fade and anti-flicker hysteresis included, so nothing pops or flickers.
Most culling assets stop at "is it in the camera frustum." SuraFix goes further: SuraFix_Room hides objects behind walls even when they're technically still in view, and SuraFix_Occluder blocks outdoor terrain, rocks, and walls — the same trick large open-world scenes use to stay fast. No bake step, no lightmapping-style wait — it works at runtime, in additive and streamed scenes alike.
Everything is modular. Use only what your project needs, drop the rest.
Features
* NEW: Distance-based LOD with cross-fade and anti-flicker hysteresis — no more hand-placed LOD groups.
* No Burst/Jobs dependency — a custom, time-sliced main-thread architecture that's predictable and easy to debug, with no black-box compile step.
* Room-based occlusion — hides objects behind walls, not just outside the camera frustum.
* Outdoor occlusion (Bounds or Physics raycast) for large open scenes.
* Distance-based streaming with full load/unload logic.
* Renderer-level culling for MeshRenderer and SkinnedMeshRenderer.
* Light and shadow culling for performance-critical scenes.
* Particle effect support, including ParticleSystemRenderer-based visibility.
* Animation pausing outside the configured visibility range.
* Player-based tracking for dynamic streaming and culling.
* Optional Addressables integration with no hard package dependency.
* Addressable key repair + scene-to-placeholder conversion editor tools.
* Compatible with Built-in, URP, HDRP, and custom render pipelines — no shader or pipeline-specific dependencies.
