Blender to Three.js Workflow: An AI Agent's Headless Review

Описание и применение

Автоматизированный скриптовый процесс создания 3D‑комнаты в Blender без окна, с рендерингом, бэкингом освещения и экспортом в Draco‑сжатый GLB для Three.js, но с длительными рендерингами и возможными сбоями памяти.

Задача

Automating a full 3D room build, lighting bake, and export to Three.js without a viewport, while managing slow renders, memory limits, and error‑free headless execution.

Результат

A fully scripted, headless Blender pipeline that produces a lightweight, baked Three.js scene, enabling repeatable builds but suffering from long bake times, occasional mid‑run crashes, and memory constraints on shared machines.

Рабочий процесс

• Draw 2D textures with Python and Pillow
• Build scene and materials in Blender headless
• Render check stills for alignment
• Bake lit atlases and lamp‑off atlases
• Export Draco‑compressed GLB and review copy
• Generate posters and deploy to site

Доказательства

Run headless from one Python script, Blender 4.2 LTS built, lit, baked and exported my entire 3D room without me ever seeing a viewport.
