这次教学主要是介绍Tiled Diffusion这个插件的分块出图功能，

这个插件的名字是：MultiDiffusion with Tiled VAE

我的教学都集中在绘制过程，所以如果你不清楚插件怎么安装请移步别的博主写的教程。

这次要画的是：春夏秋冬

我比较懒所以用英语描述春，夏，秋，冬 四个季节的活就交给了。。。。。chatgpt（这里感谢一下啊群里朋友给的服务接口）。

春天的提示词:

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.

夏天的提示词：

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.

秋天的提示词：

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.

冬天的提示词：

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.

全局提示词：

(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)

因为是描述野外风景所以还要加上：

wild scenery,extremely complex background,field,

狂野的风景，极其复杂的背景，田野，

对画面质量的控制：

film grain,Fujifilm XT3

胶片颗粒，富士胶片XT3，

（这几个提示词主要是跟这次用的大模型有关，后面我会解释）

最后是通用的负面控制语句：

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

这次我们使用的大模型是：Realistic Vision_V4.0 

这个系列的大模型是用专业摄影照片训练，有极强的光影表现力，所以对于图片的描述加入胶片感，相机类型，和照片类型相关的提示词非常敏感，所以特别加入：胶片颗粒，富士胶片XT3。来控制画面质量

好了前期工作做得差不多了，进入文生图界面，首先切换到大模型Realistic Vision_V4.0 

在tag中加入通用起手式，质量控制语句就，反向控制语句

注意：这里不需要加入对于四季的描述

打开Tiled Diffusion插件，选择方案：Mixture of Diffusers 这个方案适用于多个分块图像拼接，我们要把春夏秋冬四季都拼接到一张图里，所以用这个方案最合适。

另一个方案MultiDiffusion 的用法感兴趣的可以参考我的教学:

stable diffusion文生图教学-----超现实主义

采样器选择：euler a（其实选别的也可以，风景画要求精度不高，我选第一个主要是快）

采样步数：20（这个后期还要改，先默认不动）

分辨率：1024x512,（风景画以宽度为主，表现力更好）

方案选择：MultiDiffusion

潜空间分块宽度：128（1024÷8）潜空间分块高度：64（512÷8）

分块宽度和高度对应分辨率，是分辨率的1/8，

潜空间分块重叠：16（范围16-32，空间分块重叠影响每个分块之间的融合度，太多会互相污染，太少融合又不太好）

潜空间分块单批数量：8（越大越快，但是容易爆显存，如果你显存小就改小一点，我显存是12G，所以直接封顶设置8）

启用Tiled Diffusion，启用分区提示词控制

来到分区提示词部分

启用控制，点击创建文生图画布创建一张画布，画布的大小就是上面你设置的分辨率大小

点开区域1，启用区域1，选择前景，然后就会在画布上出现一个分块，你可以拖动分块移动位置，也可以在下面改动，X,Y轴表示分块位置，W，H表示宽和高

依次设置4个分块

注意：分块和分块之间必须有一点重叠，这样在出图的时候不同分块里的图像会自动融合过度Feather是羽化的意思，数值越大重叠部分图像越淡

然后在每个分块中填入提示词

这里的提示词需要有两个部分分别是：1.场景，2.对季节的描述

场景部分的提示词放在最前面：wild scenery,extremely complex background,field

然后接着对季节的描述，完整提示词如下：

春天的提示词:

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.

夏天的提示词：

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.

秋天的提示词：

wild scenery,extremely complex background,field，

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.

冬天的提示词：

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.

填好提示词后，最后修改两个地方

20步就可以出图，但是如果推导步数高融合的效果更自然一点，所以最后我设置成了80步

然后就可以出图了，开跑~~~~~~

最后一个小技巧：如果你用比较小的步数（20-30）觉得融合的不好，你还可以使用
