LODify: Full-Scenario Scene Optimization LODify is a comprehensive performance optimization tool designed for massive Blender scenes. Whether you are dealing with heavy architectural visualization, large game environments, or complex kitbashing scenes, LODify helps you manage textures, geometry, shader details, and viewport performance efficiently.

New in v2.6:

Non-Blocking Architecture: Most operations (Resizing, Geometry Setup, Shader Updates) now run asynchronously or in background subprocesses, keeping the Blender UI responsive even when processing thousands of objects.

Smart Worker Process: Texture resizing now utilizes a separate process to bypass the Python GIL, ensuring maximum performance.

✨ Key Features

1. 🖼️ Texture Optimization (Asynchronous)

Smart Scanner: Automatically scans all textures in the scene, identifying memory hogs and sorting them by size or VRAM usage.

Hybrid Resizing Engine:

Native Mode: Uses Blender's internal API for maximum compatibility.

Performance Mode: Uses a bundled, lightweight PIL backend (running in a subprocess) to batch resize textures rapidly without freezing the interface.

Camera-Based "AI" Optimization: intelligently calculates the required texture resolution for every object based on its screen coverage in the active camera view.

Non-Destructive Workflow: Switch between "Original" and "Optimized" resolution sets with a single click. Includes safeguards for HDR/EXR files.

2. 📉 Geometry LOD System

Dual Algorithms:

Decimate Modifier: Fast, standard reduction for general props.

Geometry Nodes: High-quality topology preservation using advanced node groups.

Smart Protection: Includes a "Safety Floor" (Min Ratio/Min Faces) to prevent close-up objects or low-poly meshes from losing essential details.

Async Batch Processing: Setup, Update, and Apply modifiers on thousands of objects using a non-blocking modal operator.

3. 👁️ Viewport & Shader Optimization

Distance Culling: Automatically downgrades viewport display types based on distance (Textured → Solid → Wire → Bounds) to boost FPS while working.

Shader LOD (Experimental): Dynamically reduces Normal Map and Displacement strength for distant objects to reduce render noise and memory overhead.

Snapshot Restoration: Remembers the original display state of every object, ensuring a perfect reset when optimization is disabled.

4. 📊 Scene Analysis Tools

Collection Analyzer: Color-codes the Outliner collections based on vertex count weight, helping you instantly spot heavy assets.

View Analyzer: Visualizes heavy objects directly in the 3D Viewport using a heatmap overlay.

📦 Compatibility Blender Version: 4.2.0 and above.

Dependencies: Includes a bundled pillow wheel (Python 3.11 compatible) for accelerated image processing. No manual installation required.

LODify: 全场景性能优化大师 LODify 是一款专为 Blender 大场景设计的综合优化工具。无论你是处理繁重的建筑可视化项目、大型游戏场景还是复杂的资产库，LODify 都能帮你高效管理贴图、模型几何、材质细节与视窗性能。

v2.6 新特性：

全异步架构：绝大多数耗时操作（如贴图缩放、几何体计算、材质更新）均采用异步或子进程处理，即使处理数千个物体，Blender 界面也不会卡死。

智能子进程 Worker：贴图处理现已移至独立进程，绕过 Python GIL 锁，性能大幅提升。

✨ 核心功能

1. 🖼️ 贴图优化 (异步)

智能扫描：自动列出场景内所有贴图并按显存占用排序，快速定位性能瓶颈。

混合缩放引擎：

原生模式：使用 Blender API，兼容性最强。

极速模式：调用内置的 PIL 子进程进行后台批量处理，无需等待。

相机视角智能优化：根据物体在相机视角下的屏幕占比，自动计算每一张贴图所需的最佳分辨率。

无损工作流：支持在“原图”和“优化图”之间一键切换，并自动保护 HDR/EXR 环境贴图。

2. 📉 几何体 LOD 系统

双重算法：

减面修改器：速度快，适合通用资产。

几何节点 (Geometry Nodes)：拓扑质量更高，适合对造型有要求的物体。

智能保护：内置“安全底限”（最小比例/最小面数），防止近景物体或低模被过度减面。

批量异步处理：通过 Modal Operator 异步处理修改器的安装、更新与应用。

3. 👁️ 视窗与材质优化

距离分级显示：根据物体距离相机的远近，自动降级显示模式（材质 → 实体 → 线框 → 包围盒），显著提升操作流畅度。

材质 LOD (实验性)：根据距离自动降低法线（Normal）和置换（Displacement）强度，减少远景噪点和渲染开销。

快照恢复：自动记录优化前的物体状态，确保一键重置时完美复原。

4. 📊 场景分析工具

集合分析器：根据顶点数量权重对集合进行颜色标记。

视图热力图：直观显示场景中哪些物体面数过高。
