SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires three.

What problem does it solve? Loading 3D assets in Three.js involves many loader classes, async patterns, compression formats, and configuration details that are easy to get wrong, leading to broken textures, failed model loads, or stalled progress indicators. ## Core Features & Use Cases - Model Loading: Load GLTF/GLB, OBJ, FBX, STL, and PLY models with support for Draco geometry compression and KTX2 compressed textures. - Texture & Environment Loading: Load standard textures, cube maps, and HDR/EXR environment maps with correct color space, wrapping, and PMREM prefiltering for PBR rendering. - Progress & Error Handling: Coordinate multiple loaders with LoadingManager, promisify loaders for async/await, and implement retry, timeout, and fallback strategies. - Use Case: When building a product configurator that displays a GLB model with an HDR environment and a loading progress bar, use this Skill to wire up GLTFLoader, RGBELoader, and a LoadingManager correctly. ## Quick Start Show me how to load a GLB model with Draco compression and an HDR environment map in Three.js with a loading progress indicator.

Frequently Asked Questions about threejs-loaders

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I load a GLTF or GLB model in Three.js?▼

Use GLTFLoader from three/addons/loaders/GLTFLoader.js and call loader.load with the model URL and a callback. The callback receives a gltf object whose scene property you add to your scene, and whose animations array can be played with AnimationMixer.

How to track loading progress for multiple Three.js assets?▼

Create a THREE.LoadingManager and pass it to each loader's constructor. Set manager.onProgress to receive per-file updates and manager.onLoad to detect when all assets finish, which is useful for driving a progress bar.

Does GLTFLoader support Draco compressed models?▼

Yes, GLTFLoader supports Draco compression through DRACOLoader. Create a DRACOLoader, set its decoder path to the Draco decoder files, call preload, then attach it with gltfLoader.setDRACOLoader before loading the compressed model.

How do I use an HDR environment map in Three.js?▼

Load the HDR file with RGBELoader, set texture.mapping to THREE.EquirectangularReflectionMapping, and assign it to scene.environment. For PBR quality, pass the texture through PMREMGenerator.fromEquirectangular to generate a prefiltered environment map.

Why does my loaded texture look washed out in Three.js?▼

The texture likely has the wrong color space. Set texture.colorSpace to THREE.SRGBColorSpace for color and albedo maps, and use linear color space for data maps like normal or roughness textures, then set needsUpdate to true.

Can I await Three.js loaders with async/await?▼

Loaders use callbacks, but you can wrap loader.load in a Promise that resolves on success and rejects on error. This enables async/await syntax and Promise.all for loading multiple assets concurrently.
