Can this skill help with custom shader implementation?

Yes, it provides the necessary technical patterns and data mapping required to connect glTF attributes like normals, tangents, and UVs to your shader pipeline.

How do I use it to debug a specific loading error?

Share the error message and the model you are trying to load; the skill identifies missing features or spec violations based on your current loader's capabilities.

How does the 5-phase progression help developers?

It breaks down the massive glTF specification into logical milestones, allowing developers to master simple geometry before moving to complex PBR materials and node hierarchies.

Does it support both .gltf and .glb formats?

Yes, it understands the structures of both JSON-based .gltf files (including external/embedded buffers) and self-contained binary .glb files.

Game Development

Guides the implementation of glTF 2.0 compatibility through a systematic 5-phase progression and debugging framework.

About

This skill provides domain-specific expertise for building 3D asset loaders, specifically optimized for developers working with graphics APIs like wgpu. It structures the complex task of glTF implementation into a manageable 5-phase plan—moving from basic geometry and transforms to full PBR material support and complex scene hierarchies. By analyzing Khronos sample models and mapping them to specific implementation milestones, it helps developers identify missing features, debug loading failures, and validate their renderer's compatibility with the glTF 2.0 specification.

Key Features

Automated validation against Khronos sample assets
Guidance on coordinate systems, TRS transforms, and scene hierarchies
Deep technical analysis of glTF JSON and binary (GLB) structures
Structured 5-phase glTF 2.0 implementation roadmap
Debugging support for vertex attributes, buffer layouts, and PBR workflows
39 GitHub stars

Use Cases

Debugging why a specific GLB model fails to render or load correctly
Implementing a custom 3D asset loader in Rust or C++
Learning the glTF 2.0 specification through systematic implementation
