[閒聊] NovelAI 招喚術與咒文詠唱心得

我已經10年沒有在ptt發文了 格式跑掉不要怪我

這裡不討論 NovelAI 跟StableDiffusion 之間的八卦

我們來好好研究一下關於招喚術以及其詠唱咒文的心得

目前最好用的 Web UI:
https://github.com/AUTOMATIC1111/stable-diffusion-webui

使用方式(設定要完全照著做才有二次元特化):

簡易使用方式(圖文):

初級招喚術書:
https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/Features

為了方便用中文溝通 以下是形容詞對應：
Prompt = 咒文
Negative Prompt = 結界
Sampling Steps = 多重詠唱
Sampling Method = 咒文語言
CFG Scale = 注入的魔力量
Seed = 隨機

本文：

1. 咒語順序很重要

構圖先做 再做細節 最後才做光影

咒文會按照詠唱順序生效 已經固定的結構會很難修正

如果: 紅髮, 金髮 -> 那出來的會是全紅 金色會出不來

所以在詠唱的初期定義好身體結構也很重要

如果初期骨架是歪的 後面要下很多咒文才修的回來

當 [頭 -> 五官 -> 身體骨架 -> 手腳] 都完成後

就可以開始放配件來幫助填空

例如: 項鍊 戒指 手環

最後才開始調光

2. 咒語有比重 比重很重要

把咒文加上()就可以提高1.1比重

要往上我建議你直接打 (咒文:比重)

例如 (blue eye:1.5)

你的詠唱越加越長的話 前面的咒文會需要重新調整比例

這樣基礎的形才不會跑掉

比重好像不能超過1.9

但是如果你需要1.9也代表你順序有問題 應該重排咒文

3. 結界

一個萬用的就差不多了

在文字生成階段只要萬用的就好

等第二階段用圖生圖 (img2img) 的時候

才需要在萬用的上面 加入針對性的防禦結界

-- 基礎招喚 --

多重詠唱用 20 - 35 之間就夠了 我慣用 27

語言用 DDIM 這東西跟盧恩文字一樣屌 用就對了

長寬決定你的畫面構圖 看你需求 寬一點人的腳就很難畫進去

用512x512可以容易全身 用768x512比較好畫 用832x512比較容易當桌布

Restore Faces 可以算是臉部防禦特化 但是我不愛用

魔力量CFG很重要

我在文字生成階段會用12

在圖生圖階段會用14

用越多魔力 招喚出來的東西越精準

但是太精準也不好 因為你不是賢者 你的咒文一定爛透了

還是讓 AI 自由發揮一點比較好

------------ 招喚示範 ------------

講這麼多 我還是先上完成圖給你們看

一樣要放咒文

要拿掉一些已經畫的很好的咒文

增加一下畫的不好的咒文

基礎人體比例構造咒文的要留著

多重詠唱step開多一點65

語言一樣用 DDIM

長寬要一樣

魔力量CFG用高一點14

Denoising strength 是允許變動量 開小一點 0.43

咒語:
