這次教學主要是介紹Tiled Diffusion這個插件的分塊出圖功能，

這個插件的名字是：MultiDiffusion?with Tiled VAE

我的教學都集中在繪制過程，所以如果你不清楚插件怎么安裝請移步別的博主寫的教程。

這次要畫的是：春夏秋冬

我比較懶所以用英語描述春，夏，秋，冬 四個季節(jié)的活就交給了。。。。。chatgpt（這里感謝一下啊群里朋友給的服務接口）。

春天的提示詞:

Spring: Spring is the season when the earth awakens, full of vitality and hope. One can depict the blooming flowers, such as cherry blossoms, rhododendrons, and peach blossoms, creating a colorful and vibrant floral landscape. Additionally, the lush greenery with tender new leaves adorns the entire land, while birds sing joyfully from the branches. Spring also brings warm sunlight and gentle breeze, providing a sense of comfort and delight.

夏天的提示詞：

Summer: Summer is a hot season, filled with passion and energy. One can depict the vast fields and verdant trees of summer, where golden wheat sways in the wind under the bright sunshine. Forests offer shade and coolness, while rivers and lakes sparkle like jewels, adorned with blooming lotus flowers and water birds. The tropical rainforests also showcase exotic flowers and plants in a myriad of colors, captivating the senses.

秋天的提示詞：

Autumn: Autumn is a season of harvest and change, characterized by vibrant and romantic colors. One can depict the multitude of colors that adorn the land, as leaves transition from green to yellow, orange, and red, creating a sea of golden and fiery hues. The autumn sky is clear blue, and sunlight filters through the leaves, providing a warm and pleasant ambiance. Additionally, autumn is a season of abundance, with golden rice fields and wheat fields, evoking joy and prosperity.

冬天的提示詞：

Winter: Winter is a cold and pure season, imbued with tranquility and mystery. One can depict the winter landscape covered in a white blanket of snow, with snow-capped mountains and frozen lakes, offering a serene and peaceful atmosphere. Icicles glisten on tree branches, reflecting a myriad of colors in the sunlight. The howling winds bring the chill of winter, while the short daylight hours paint the dusk sky in a deep red, creating a warm and cozy feeling.

全局提示詞：

(photorealistic:1.3),((masterpiece:1.2),(best quality:1.2),RAW photo,dlsr),( HDR,UHD,8K, Highly detailed, ultra-fine painting, sharp focus, physically-based rendering, extreme detail description, Professional, Vivid Colors)

因為是描述野外風景所以還要加上：

wild scenery,extremely complex background,field,

狂野的風景，極其復雜的背景，田野，

對畫面質(zhì)量的控制：

film grain,Fujifilm XT3

膠片顆粒，富士膠片XT3，

（這幾個提示詞主要是跟這次用的大模型有關，后面我會解釋）

最后是通用的負面控制語句：

illustration,3d,sepia,painting,cartoons,sketch,(worst quality:2),(low quality:2),(normal quality:2),

這次我們使用的大模型是：Realistic Vision_V4.0?

這個系列的大模型是用專業(yè)攝影照片訓練，有極強的光影表現(xiàn)力，所以對于圖片的描述加入膠片感，相機類型，和照片類型相關的提示詞非常敏感，所以特別加入：膠片顆粒，富士膠片XT3。來控制畫面質(zhì)量

好了前期工作做得差不多了，進入文生圖界面，首先切換到大模型Realistic Vision_V4.0?

在tag中加入通用起手式，質(zhì)量控制語句就，反向控制語句

注意：這里不需要加入對于四季的描述

打開Tiled Diffusion插件，選擇方案：Mixture of Diffusers 這個方案適用于多個分塊圖像拼接，我們要把春夏秋冬四季都拼接到一張圖里，所以用這個方案最合適。

另一個方案MultiDiffusion 的用法感興趣的可以參考我的教學:

stable diffusion文生圖教學-----超現(xiàn)實主義

采樣器選擇：euler a（其實選別的也可以，風景畫要求精度不高，我選第一個主要是快）

采樣步數(shù)：20（這個后期還要改，先默認不動）

分辨率：1024x512,（風景畫以寬度為主，表現(xiàn)力更好）

方案選擇：MultiDiffusion

潛空間分塊寬度：128（1024÷8）潛空間分塊高度：64（512÷8）

分塊寬度和高度對應分辨率，是分辨率的1/8，

潛空間分塊重疊：16（范圍16-32，空間分塊重疊影響每個分塊之間的融合度，太多會互相污染，太少融合又不太好）

潛空間分塊單批數(shù)量：8（越大越快，但是容易爆顯存，如果你顯存小就改小一點，我顯存是12G，所以直接封頂設置8）

啟用Tiled Diffusion，啟用分區(qū)提示詞控制

來到分區(qū)提示詞部分

啟用控制，點擊創(chuàng)建文生圖畫布創(chuàng)建一張畫布，畫布的大小就是上面你設置的分辨率大小

點開區(qū)域1，啟用區(qū)域1，選擇前景，然后就會在畫布上出現(xiàn)一個分塊，你可以拖動分塊移動位置，也可以在下面改動，X,Y軸表示分塊位置，W，H表示寬和高

依次設置4個分塊

注意：分塊和分塊之間必須有一點重疊，這樣在出圖的時候不同分塊里的圖像會自動融合過度Feather是羽化的意思，數(shù)值越大重疊部分圖像越淡

然后在每個分塊中填入提示詞

這里的提示詞需要有兩個部分分別是：1.場景，2.對季節(jié)的描述

場景部分的提示詞放在最前面：wild scenery,extremely complex background,field

然后接著對季節(jié)的描述，完整提示詞如下：

春天的提示詞:

wild scenery,extremely complex background,field，

Spring: Spring is the season when the earth awakens, full of vitality and hope. One can depict the blooming flowers, such as cherry blossoms, rhododendrons, and peach blossoms, creating a colorful and vibrant floral landscape. Additionally, the lush greenery with tender new leaves adorns the entire land, while birds sing joyfully from the branches. Spring also brings warm sunlight and gentle breeze, providing a sense of comfort and delight.

夏天的提示詞：

wild scenery,extremely complex background,field，

Summer: Summer is a hot season, filled with passion and energy. One can depict the vast fields and verdant trees of summer, where golden wheat sways in the wind under the bright sunshine. Forests offer shade and coolness, while rivers and lakes sparkle like jewels, adorned with blooming lotus flowers and water birds. The tropical rainforests also showcase exotic flowers and plants in a myriad of colors, captivating the senses.

秋天的提示詞：

wild scenery,extremely complex background,field，

Autumn: Autumn is a season of harvest and change, characterized by vibrant and romantic colors. One can depict the multitude of colors that adorn the land, as leaves transition from green to yellow, orange, and red, creating a sea of golden and fiery hues. The autumn sky is clear blue, and sunlight filters through the leaves, providing a warm and pleasant ambiance. Additionally, autumn is a season of abundance, with golden rice fields and wheat fields, evoking joy and prosperity.

冬天的提示詞：

wild scenery,extremely complex background,field，

Winter: Winter is a cold and pure season, imbued with tranquility and mystery. One can depict the winter landscape covered in a white blanket of snow, with snow-capped mountains and frozen lakes, offering a serene and peaceful atmosphere. Icicles glisten on tree branches, reflecting a myriad of colors in the sunlight. The howling winds bring the chill of winter, while the short daylight hours paint the dusk sky in a deep red, creating a warm and cozy feeling.

填好提示詞后，最后修改兩個地方

20步就可以出圖，但是如果推導步數(shù)高融合的效果更自然一點，所以最后我設置成了80步

然后就可以出圖了，開跑~~~~~~

最后一個小技巧：如果你用比較小的步數(shù)（20-30）覺得融合的不好，你還可以使用

中的技巧，添加細節(jié)后放大，下面就是我添加細節(jié)并放大后的效果
