How do I prevent texture memory leaks?

Always call texture.dispose() and material.dispose() when removing objects from your scene to explicitly free up GPU memory.

What is the best way to load multiple textures efficiently?

Wrap the TextureLoader in a Promise and use Promise.all to load your color, normal, and roughness maps concurrently to avoid loading bottlenecks.

Can I use a canvas or video as a texture source?

Yes, Three.js provides CanvasTexture and VideoTexture classes that allow you to use dynamic 2D content as surfaces for 3D objects.

Why are my ambient occlusion (AO) maps not working?

In Three.js, AO maps require a second set of UV coordinates. You must set the 'uv2' attribute on your geometry, often by copying the primary UV attribute.

How do I handle color spaces for textures in Three.js?

Use THREE.SRGBColorSpace for color/albedo textures to ensure accurate color reproduction, while keeping data textures (normal, roughness, metalness) as NoColorSpace.

Game Development

Implements and optimizes Three.js textures, UV mapping, and environment maps for high-performance 3D web graphics.

This skill provides a comprehensive toolkit for managing textures within the Three.js ecosystem, covering everything from basic image loading to advanced PBR material mapping and procedural texture generation. It assists developers in configuring critical settings like color spaces, wrapping modes, and anisotropic filtering to ensure visual fidelity and performance. Whether you are building immersive 3D environments with HDR skyboxes, dynamic reflections via CubeCamera, or custom shader-based UV transforms, this skill offers production-ready patterns and best practices for modern WebGL development.
