名前つきカメラ 3 台の物撮りを 1 回の仕事で（cameras=[...]）

名前つきカメラ 3 台の物撮りを 1 回の仕事で（cameras=[...]）。本番の GPU で描いた本物の結果と、そのまま動く bpy スクリプト、設定、GPU 秒。スクリプトの URL を scene_url に渡せば同じものが出ます。

Blender の警告

• cameras: frame 1 rendered from Front, Top, Iso (frame_0001.. in that order)
• environment preset 'studio' replaced the scene's world (HDRI lighting)

ex15_product_cameras.py。シーン・カメラ・コマ範囲だけを組み、解像度・サンプル・ノイズ除去・GPU はサービスが決めます。

"""JANCTION Render example 15: a ceramic mug from three named cameras in one job (product shots, cameras=[...]).

Reproduce: render_final(scene_url="https://render.janction.jp/samples/ex15_product_cameras.py",
                        cameras=["Front", "Top", "Iso"], width=1200, height=1200, samples=128, environment="studio")
The scene defines three camera objects; the service renders the same frame from each and returns one PNG
per camera (camera_files maps the names). render_preview with the same cameras tiles them in one sheet.
