【解説】見えない構図イラスト生成（Illustrious-XL系）

# 1.はじめに

　この記事では、見えない構図のイラスト生成をIllustrious-XL系モデルで行う方法を解説していきます。

■見えない構図 (みえないこうず)とは【ピクシブ百科事典】

https://dic.pixiv.net/a/%E8%A6%8B%E3%81%88%E3%81%AA%E3%81%84%E6%A7%8B%E5%9B%B3

　R-18イラストを公開する際には、検閲処理（モザイク修正）が必須です。

　ただし、そもそも局部を隠してR-18の基準を回避しているイラストであれば、その処理は不要にできます。

　また、完全に回避できなくても軽減できたりします。

　特に、男の娘ジャンルにおいては、陰茎の描写が異性愛ジャンルと比べて多くなりがちなので、その分だけ修正工数がかさむ事が多いです。

　また、見えないからこそ、想像力をかき立てられる効果もあります。この効果は、叡知な物語の導入パートなどで機能しやすい特徴です。

　そのような効果を狙う為に、この方法を解説していきます。

# 4.解説

　見えない構図にしたい場合は、下記のタグを含めるようにしています。

```

convenient censoring

←（物に隠れて）見えない構図　※物は、タオル (towel) や 葉っぱ(leaf) 等

convenient {身体部位}

←身体部位（例：腕 {arm}, 脚 {leg} ）で自然に隠されている構図　※直接的に局部を隠す行為 (covering privates, covering crotch) とは意味合いが異なります。

soap censor, soap bubbles

←泡での検閲処理、石鹸の泡

light censor

←光での検閲処理

steam censor

←湯気での検閲処理

{身体付属部位} censor

←身体付属部位（例：髪 {hair}, 尻尾 {tail} ）での検閲処理

novelty censor

←ネタオブジェクト（例：見せられないよ！{can't show this \(meme\)} ）での検閲処理

character censor

←キャラクターでの検閲処理

bulge, covered testicles

←もっこり、覆われた睾丸

erection under clothes

←服の下での勃起

```

※ネタオブジェクトは、例えば次のようなものです。

```

3boys, akiyama mizuki, masterpiece, otoko no ko,

mmm threesome, mmf threesome, group sex, gangbang, molestation, chikan, convenient censoring, novelty censor, character censor,

groping,

surprised, confused, blush,

<年齢タグL>, petite, pink eyes, nude, wet,

size difference, height difference, age difference,

faceless male, ugly man, fat man, old man,

stone floor,

onsen, bamboo fence, night, shadow, dark background, horror \(theme\)

Negative prompt: worst quality, bad quality,, hetero, pussy, vaginal, vagina, cameltoe, breasts, female, woman, girl, she, uterus, cervix, impregnation

```

　逆に、見える構図にしたい場合は、次のタグがあります。

　これは、見えない構図用のネガティブプロンプトとしても使用できそうです。

```

uncensored

←無検閲

```

　また、泡 (soap) や光 (light) や湯気 (steam) などでの検閲処理はよくあるパターンなので、それらの要素はあるが検閲処理は除外したい時などにも使用できそうです。

　※無検閲画像は公開前に別途検閲処理をする必要があります。

　加えて、今回は使用しなかったのですが、レーティングタグを含めても良いかもしれません。Illustrious-XL系だと次のものです。

```

general

←全年齢対象

sensitive

←R15ぐらい？

questionable

←R17.9ぐらい？

explicit

←R18

```

　更に加えて、白濁液描写の生成に使用していたアプローチを流用する事で、泡や光や湯気の濃さを上げられそうです。

【解説】白濁液差分生成方法（プロンプト例あり）

※本記事での画像生成AIは、Stable Diffusion 1.5系列です。 # 1.概要 この記事は、白濁液差分を生成できるようになることを目的としています。 前回の記事で比較的簡単にNSFWな男の娘イラストを生成できるようになりましたが、白濁液がほぼ見えないという問題がありました。 今回の記事では、元画像をもとに白濁液差分を...

　これらを組み合わせる事で、見えない構図イラストの生成率が上がると思います。

# 5.おわりに

　将来的には、オーダーメイドAIコンテンツがコンテンツ業界の主流になっていくと考えています。ユーザ自身がAIにコンテンツ提供を依頼し、それをユーザが享受するようなサービスです。

　例えば、今でもGeminiやChatGPTなどのサービスにシナリオ生成をお願いして楽しむ事ができています。

https://ch.dlsite.com/matome/522131

　そして、それらのサービスでは、文章以外のコンテンツ（例：画像や音声）の生成にもアクセスできるようになってきています。

　その現実的な延長線として、オーダーメイドAIコンテンツが想定されます。

　例えば、大量のコンテンツを持つ大企業がAIにそれらを学習させ、オーダーメイドAIコンテンツを提供していくなどです。

　そのような中で、個人クリエイターや中小企業は、どのようなキャリア戦略や経営戦略をするのが良いのでしょうか。

　正解は無いのですが、ニッチ戦略が基本です。

　例えば、特定の世界観やジャンルに深く根ざした「小規模だが熱狂的なファン層」を持つ領域に特化することが挙げられます。

　大企業は大量のデータと資本を武器に、汎用的で幅広いユーザに届く巨大サービスを構築できます。

　しかし、巨大サービスはどうしても大衆的なものであり、「ある狭いテーマを異常なほど深掘りした表現」や「少人数コミュニティの文化・文脈に強くフィットした創作」は不得手です。

　ここに、個人クリエイターや中小企業が参入する余地があります。

　そして、その一つとして、本チャンネルで紹介しているような事も含まれると考えています。

　あなたの将来の羅針盤作りにて、一助となれていれば幸いです。
