AI繪畫-Stable Diffusion實戰——如何穩定繪制全身圖（咒語）？

首發創作賽

眾所周知，使用Stable Diffusion進行繪制全身圖時，總是會臉崩。今天就分享一下來自模型geminixMix_V3大佬的干貨，如何能穩定的繪制全身圖。

提醒：不可說原因，部分配圖已刪除，請自行生圖O(∩_∩)O

1.本文中使用geminixMix_V3模型在SD1.5的環境下生成,CKPT下載處放在最后.

2.貼上準備好的prompt,下面是已經幫大家分段好的提示詞,

>>第一段是定義畫面和圖片品質

>>第二段式形容角色

>>第三段式定義環境場景

大家可以依照自己的需求做出調整，最好可以把從頭到腳的配件都寫進去Prompt,可以確保萬無一失,尤其是鞋子.

3.參數設定:

Sampler: DPM++ SDE Karras,

Sampling Steps: 30,

尺寸: 576X1024,

CFG scale: 7,

種子:自定義或 1,

Hires.fix打勾V,

放大算法: 個人最常用 Lanczos 可以多方嘗試其他算法看效果

>>Hires steps: 0

>>Denoising: 0.3

>>Upscale by(放大倍數): 2.0

4.LoRA:

本分享使用2個LoRA：

>>GeminiX_201_NightPunkV1 權重 0.15

>>GeminiX_033_SofiaV1 權重 0.35

5.生成

按下生成后依照顯卡等級(3080約200秒),就會生成一個全身靚妹圖,prompt中的 fullbody: 權重建議設定 1.4~1.5,這樣才有大機率生成全身的人體下,還能LoRA保留角色臉部特整,這里附上 0.5/1.0/1.5/2.0 幾種權重的差異.(2.0時LoRA臉部特征已經有點跑掉了)

6.設定細項解釋

這個尺寸576X1024加上 2X 的Hires.fix,以及 fullbody:1.4 的prompt,在全身的構圖且無須其他插件下,讓臉部可以清晰生成,并且LoRA特征不會跑掉.

7.下面是Prompt:

Prompt:

(photorealistic:1.4), (extremely intricate:1.2),(exquisitely detailed skin), cinematic light, ultra high res, 8k uhd, intricate details, Movie Light, film grain, dreamlike, perfect anatomy, best shadow, delicate, RAW, realistic, ((SFW:1.9)), ((school life)),

.Negative prompt:

8.其他:

>>LoRA是使用geminixMix_V3訓練的

>>其他的配圖都會附上prompt.
