Five real GLB files encoded as plain, quantized, Draco and Meshopt: sizes with and without gzip/Brotli, load times on fast and slow 4G, decode cost, GPU memory, visual error, and which engines and tools can open each one.

Why THREE.LOD hitches the first time a level appears, what compileAsync does not cover, what hidden levels cost every frame, and when hysteresis or a dithered fade is worth it — measured.

We drew the same 10,000 props seven ways in three.js and measured frame time, culling, memory, moving, picking and shadows. What to use, and when.

Hiding one PointLight froze our three.js test scene for 4.8 s. Why light counts force shader recompiles, what else does, and how to fix it — measured.

Load .glb files in three.js with GLTFLoader, decode Draco-compressed geometry, light PBR materials correctly, play animations and fix the usual black, tiny or missing model problems.

Load GLB models in React Three Fiber with drei’s useGLTF, decode Draco, reuse one model many times, play animations and get typed components for every model.

Why 1 unit = 1 metre, a consistent up axis and a ground-level pivot decide whether models from different packs fit together, and how each engine treats units and axes.

How to import .glb models into Blender, Unity (glTFast), Unreal Engine 5 and Godot 4, what each importer supports, and what to do with Draco-compressed files.
