GLB to OBJ Converter

This tool performs a GLB to OBJ conversion that preserves geometry, UVs, and material references where possible. It outputs an OBJ file plus an MTL file and any textures referenced by materials. The process flattens the glTF scene graph, converts coordinates to the target system, and writes faces in OBJ 1-indexed form. It handles multiple materials by creating separate MTL blocks and linking texture maps when available. The conversion is designed for static geometry; animations, morph targets, and skinning are ignored unless explicitly enabled in an advanced mode. Users benefit from broad compatibility with traditional 3D software, game engines, and asset pipelines that prefer OBJ/MTL inputs. Unique value comes from automatic texture export, material normalization, and optional scaling and axis conversion to reduce manual post-processing. Core features include robust parsing of GLB binaries, correct handling of vertex positions, normals, and UVs, material extraction, and sensible fallbacks when textures are missing. Use cases span asset re-use in modeling apps, cross-software interoperability for AR/VR previews, and quick porting of GLB assets into traditional workflows. The tool emphasizes predictable output formatting and traceable material references to minimize importer surprises and rework in downstream tools.
