360 Diffusion LoRA for SD 1.5

360 Diffusion v1

首次发布于 HuggingFace。

该 LoRA 模型基于包含 2104 张带标注图像的极广阔角投影多样化数据集进行了微调，使用的是 Stable Diffusion v1-5 模型。

该模型通过触发词 qxj 进行微调。若使用 AUTOMATIC1111 WebUI，则必须在提示词末尾添加 <lora:360Diffusion_v1:1> 以激活该模型。

渲染建议

在渲染时，建议采用 1:2 比例或正方形。以 1:1 正方形形式渲染有助于提升概念一致性（例如房间的墙壁）。

在使用 txt2img 生成大尺寸图像时，细节容易丧失连贯性，因此建议先以至少一个维度接近 512px 的较小尺寸生成图像，再通过 img2img（去噪设为 0.5）或内置的高分辨率修复功能进行放大。

有时可通过多次循环使用 img2img（去噪设为 0.5，并调整种子大小）来改善细节表现。

接缝处理

由于 Stable Diffusion 仅渲染方形和矩形图像，任何等距圆柱投影图像边缘都可能出现无法完全对齐的情况。尽管这些接缝通常较轻微，但仍有多重处理方式：

* 使用 asymmetric-tiling 扩展的 x 轴无缝拼接功能可彻底消除接缝，但此扩展可能显著降低输出质量。建议将「从第 N 步开始拼接」设置为大约 50% 的位置，以降低影响（例如使用 20 步时可设为第 9 步开始）。

* 在将图像水平向左或向右平移后，可在接缝处使用修补功能。

* 可使用 GIMP（可搭配 G'MIC）或 Photoshop 手动去除接缝。
