easy to change head with lora

V3变化：

使用全量模型重新训练

成功更高

增加只换脸功能（见下面工作流示例，2025-11-12发，现在还没发）

v3 base prompt:

移除图1人物的头发、耳环、项链、帽子等头部配饰；

将图1人物的脸替换为图2人物的脸（完全覆盖原图人脸，无残留）；

将图1人物的发型替换为图2人物的发型：（长短、颜色与图2完全一致，无原图发型残留）；

同步替换为图2人物的表情（眼神、脸部朝向与图2一致）；

新脸、新发型需适配图1场景光影，自然融合，过渡无痕迹。

V2:

V2 update

• 用更多的图集重新训练，包括了中国人和西方人以及不同性别

• 更多的训练步数

请确保图2中的人物的头部脸没有遮挡且完整清楚（Please ensure that the head and face of the character in Figure 2 are unobstructed and complete and clear）

测试环境参数：（Test environment parameters:）

qwen2509fp8 + 8 step lighting lora + 12 steps +cfg1 + euler +beta

仍存的在问题：

大多数时候脸部会变替换（Most of the time, the face will be replaced）

有些时候发型不能完整的替换 留给V3解决（Sometimes the hairstyle cannot be completely replaced and left to V3 to solve）
头或许变大,或许重要的话可以用ps液化调整一下（ bigger head ,also can photoshop it if important ）

可以换头或只换脸，下面是示例指令(中英文选其一即可)

You can change your head or just your face. Here are example instructions (choose one in Chinese or English，but Prioritize using Chinese because this is a large Chinese model)

简单指令：(Simple prompt)

不改变图1的背景和人物姿势，把图1中的人物的头换成图2中人物的头,要把图2人物的脸，头发和饰品都换到图1中现在人物的头部位置，替换后尽量保持图2人物的脸部特征和发型不变，并且融合图1环境的光影。

Without changing the background and posture of the character in image1, replace the head of the character in image1 with the head of the character in image2. The face, hair, and accessories of the character in image2 should be moved to the current position of the character's head in image1. After replacement, try to keep the facial features and hairstyle of the character in image2 unchanged, and integrate the light and shadow of the environment in image1.

Of course, you can experience more gameplay by yourself, such as whether to keep the emoji in Figure 1 or switch it to Figure 2. Please refer to the instructions as needed and try it out
