Blenderの3Dレイアウトから、Seedance 2.5でアニメ動画を作ってみた｜背景もカットも構図どおりになるか

あなたは Blender の MCP（開いている Blender につながっている）だけを使って作業します。

これから、3Dのレイアウトを土台にして、画像生成AIでアニメ調の背景とカット画像を作り、動画生成AIで2カットの短い動画にします。この作業では、その土台になる「3Dレイアウト」を Blender で作ってください。見た目のきれいさより、空間・人物の位置・カメラの構図が正確に決まっていることが大事です。

## 場面
小さな中古カメラ店の店内（夕方）。広さは横 4m × 奥行き 5m、天井 2.6m くらい。
- 奥の壁: 木の棚（3段）に古いカメラ（箱と円柱の簡単な形でよい）を十数台並べる。
- 右の壁: 窓（夕日が入る。窓の外は明るいだけでよい）。
- 中央より少し左: ガラスのショーケース（高さ 1m くらい。中の段にカメラを数台）と、その奥に木のカウンター。
- 左の手前: 入口のドア。
- 天井: 吊り下げのランプ 2つ。
- 床は木、壁はしっくい風の色。小物（値札の札、レンズの箱、小さな観葉植物など）も少し置く。
- 窓から斜めに夕日が入る明かり（暖色）と、ランプの明かり。

## 人物（仮のマネキン）
身長 1.71m の男性くらいの、関節の分かるマネキンを1体（球・円柱などの簡単な形を組み合わせてよい。顔は無くてよい。リグは無くてよい）。カット1用とカット2用で、ポーズの違う2体を作り、コレクションを分けてください（「mannequin_cut1」「mannequin_cut2」）。
- カット1: ショーケースの手前（カメラから見て右側）に立ち、上半身を少し前に傾けて、ショーケースの中をのぞき込む。右手はショーケースの上のガラスに軽く置く（手がガラスに触れていること。めり込まない・浮かない）。両足は床についていること。
- カット2: カウンターの前に立ち、両手で古いカメラ（小さな箱＋レンズの円柱）を胸の前、顔から 30cm くらいの高さに持ち上げて見ている。手がカメラに触れていること。顔はカメラの方を向く。

## カメラ（16:9、1280×720）
- 「cam_cut1」: 引きの画。入口ドアの近く、目の高さ（1.5m くらい）から、店の奥に向かって撮る。ショーケース・棚・窓が入り、マネキンの全身が画面の右寄りに入る。
- 「cam_cut2」: 寄りの画。カウンターの横、腰の高さ（1.0m くらい）から少し見上げて、マネキンの胸から上と、持っているカメラが大きく入る。背景に奥の棚が見える。
- カット1とカット2で、店の左右がひっくり返らないように（同じ側から撮る。イマジナリーラインを越えない）。

## レンダー
EEVEE か Workbench（ソリッドに色が付いた見た目でよい）で、次の4枚を 1280×720 の PNG で保存してください。
1. bg_cut1.png: cam_cut1、マネキンを隠した画（人物なしの背景用）
2. bg_cut2.png: cam_cut2、マネキンを隠した画
3. layout_cut1.png: cam_cut1、mannequin_cut1 だけ表示
4. layout_cut2.png: cam_cut2、mannequin_cut2 だけ表示
保存したら、それぞれの画像を Read で見て、上の条件（手が触れているか、足が床についているか、構図、左右）を自分で確かめ、だめなら直してから撮り直してください。

## 保存先
{保存先のフォルダ}
- camera_shop.blend
- 上の PNG 4枚
- 使った Python を build_scene.py として保存（Blender の中から書き出してよい）

最後に、日本語で、作ったもの（店の小物・マネキンの作り方・カメラの位置と焦点距離・明かり）、自分で確かめて直したところ、うまくいかなかったことを報告してください。

Redraw the reference image as a Japanese TV anime background painting of the same room, with no people. Keep the exact same camera angle, perspective, room layout and object positions as the reference: the wooden shelf with old cameras on the back wall, the glass showcase with a red cloth in the middle-left, the wooden counter behind it, the window on the right wall, the two hanging green lamps, the clock and the two posters on the left wall. Do not add or remove doors, windows, furniture or people. Setting: a small used-camera shop in the evening, warm orange sunset light coming through the window and falling on the floor and showcase. Style: clean anime background art, crisp line work, flat cel shading with clear shadow shapes, warm color palette. No film grain, no noise, no painterly brush texture, no text.

Redraw the reference image as a Japanese TV anime background painting of the same room, with no people. Keep the exact same low camera angle looking slightly upward, perspective and object positions as the reference: the long wooden shelves with old cameras and price tags, the hanging green lamp at the upper left, the round clock on the wall, the small potted plant and boxes on the counter in the foreground. Do not add or remove doors, windows, furniture or people. Setting: a small used-camera shop in the evening, warm orange sunset light from the right. Style: clean anime background art, crisp line work, flat cel shading with clear shadow shapes, warm color palette. No film grain, no noise, no painterly brush texture, no text.

Anime film still. Image 1 is the background: keep this room, camera angle, lighting and every object exactly as it is. Image 2 is a 3D layout: place one man in image 1 at exactly the same position, size and pose as the grey mannequin in image 2 — standing in front of the glass showcase, seen mostly from behind, leaning his upper body forward and looking down into the showcase, his right hand resting flat on the glass top, his left arm hanging down, both feet on the floor. Image 3 is a character sheet used ONLY for the man's face, hair, body type and clothes (messy black curly hair with a little grey at the temples, white lab coat with rolled-up sleeves, orange T-shirt, black headphones around the neck, dark grey trousers, brown sneakers). Do not copy the standing pose, the white background or the color swatches from image 3. Only one person in the picture. Same anime style as image 1: crisp line work, flat cel shading, warm sunset light. No text, no grain.

Image 2 is a 3D layout: place one man in image 1 at exactly the same position, size and pose as the grey mannequin in image 2 — seen from a low angle, chest and head large in the frame, body turned toward the right, holding an old silver-and-black film camera with both hands in front of his chest, about 30 cm below his face, looking at the camera with a delighted, slightly surprised face. Both hands touch the camera. Image 3 is a character sheet used ONLY for the man's face, hair, body type and clothes (messy black curly hair with a little grey at the temples, big round eyes, light stubble, white lab coat with rolled-up sleeves, orange T-shirt, black headphones around the neck).

Anime scene in a small used-camera shop at sunset. Character action: the man in the white lab coat, seen from behind, leans further forward over the glass showcase and peers closely at the old cameras inside; then he lightly taps the glass top twice with the index finger of his right hand. He stays in the same place; his feet do not move. Camera action: a slow, steady push-in toward the man and the showcase, eye level, no cuts. The room, furniture, window and sunset light stay exactly the same throughout; no new objects or people appear. Sound: quiet shop ambience, a soft tap on the glass, no dialogue, no music.

Anime scene in a small used-camera shop at sunset, low angle. Character action: the man with messy curly black hair turns the old film camera slightly in his hands, admiring it with a delighted smile, then slowly raises it up to his right eye as if to look through the viewfinder. Both hands stay on the camera the whole time. Camera action: static low-angle shot from waist height, almost no movement, no cuts. The shelves, lamp, clock and sunset light stay exactly the same; no new objects or people appear. Sound: quiet shop ambience, a faint click of the camera, no dialogue, no music.

Anime film still, cut 1 (wide shot). A small used-camera shop in the evening, about 4 m wide and 5 m deep. Camera at eye level (1.5 m) near the entrance door, looking toward the back of the shop.
