SKP to OBJ Converter

Purpose & User Intent: This tool solves the need to convert SketchUp SKP models to OBJ for downstream rendering, game engines, BIM workflows, and architectural visualization. Primary users include 3D artists, engineers, architects, and asset pipelines who require cross-platform compatibility. It is used when SKP content must enter OBJ-based tools such as Unity, Unreal, Blender, or renderer pipelines, while preserving geometry, materials, and textures as much as possible and maintaining scale when metadata exists.

Core Logic & Features: The converter reads the SKP repository of geometry, materials, and texture paths, then outputs an OBJ file and an accompanying MTL. Required features include exporting geometry with vertex/normal/texture indices and a corresponding MTL. Optional features include triangulation of faces, texture preservation, batch processing, and unit metadata handling. The tool aims to produce faithful geometry with deterministic results across runs, enabling reliable asset reuse.

Inputs & Outputs: Inputs: source_file (file, extension .skp, required), target_format (string, default obj, allowed obj), triangulate (boolean, optional, default true), preserve_textures (boolean, optional, default true), unit_handling (enum: preserve|scale, optional). Outputs: converted_file (OBJ), material_file (MTL) or embedded materials, optional logs/summary (JSON). Validation: required inputs must be provided; unsupported SKP versions generate a specific error; very large files may trigger chunked processing.
