"""JANCTION Render example 05: six material balls (glass, gold, skin, emission, car paint, plastic) under the studio preset.
Reproduce: render_final(scene_url="https://render.janction.jp/samples/ex05_material_balls.py",
width=1920, height=1080, samples=128, environment="studio")
Each ball is one Principled BSDF with a few inputs changed; copy the one you need.
