【修复】角色被格线切断(脚、手杖、飘起的斗篷被削掉) 新增 expand_beyond_cell(默认开启):格子只用来判定「这是哪个方向」, 角色的实际范围由它自身的连通区域决定,按质心归属确保邻居不混入。 实测 8/8 方向的裁剪框边缘 alpha 从 1.00(内容顶到边界=被切断) 降到 0.00,S 方向高度 326→356、E 方向宽度 150→188 把缺的部分找了回来。 代价是需要两遍扫描(先求全序列并集框再提取),耗时 4.7s→14.9s。 【规则】每个参数都必须有中文 tooltip,作为以后的统一约定 全仓库 26 个节点 169 个参数,此前缺 115 个,现已 100% 覆盖。 tooltip 写「怎么调」而不只是「是什么」:给取值区间的实际影响、 推荐值与踩坑提示(如 OpenAI/ZenMux 的地址栏不能带 :// , 素材拆分节点用于动画序列时顺序会漂移等)。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

ZenMux API 连接节点
|
||
===================
|
||
通过 ZenMux 聚合平台(https://zenmux.ai)调用其收录的所有文本类模型。
|
||
|
||
特性:
|
||
- 模型下拉覆盖 ZenMux 全部文本模型,按「厂商/模型名」排序聚类;
|
||
ComfyUI 下拉自带搜索,输入厂商前缀(如 "anthropic/")即可快速过滤。
|
||
- 每个模型选项后面直接标注输入/输出价格(USD / 百万 token)。
|
||
- usage_stats 输出单次运行的 token 消耗与费用(按快照单价折算,
|
||
汇率可用 usd_to_cny 参数调整)。
|
||
- 具备常规 API 节点的完整参数:api_key、system/user prompt、seed、
|
||
temperature、top_p、max_tokens、以及可选的多模态图像输入与代理。
|
||
- 默认模型 openai/gpt-5.4-nano。
|
||
- 随节点分发 models_snapshot.json,无网络也能列出模型;价格与列表可用
|
||
build_snapshot.py 重新拉取更新。
|
||
|
||
注:ZenMux 采用 OpenAI 兼容协议,chat 端点为
