空间物理 LoRA · Spatial & Physics LoRA (MiniMax-H3)

空间思维与物理逻辑 LoRA，基于 MiniMax-H3（Comfy-Org/MiniMax-H3）训练，让模型学会纯物体的空间关系与物理运动（碰撞、堆叠、掉落、遮挡等）。

本 LoRA 专注物体物理。

目前还是训练和测试阶段，一些素材片段以及打标问题导致LORA还不是特别稳定。下一阶段准备修复后重新训练。目前LORA也是可以使用，强度建议0.3 ~ 0.5。纯属是在原模型基础上稍微增强一点物理反馈。 最新是重新训练到了wushu_spatial_physics_clean_3000_pruned.safetensors 版本。

视频对比

实测用了这个LORA，视频整体提升真实感物理的逻辑，比如物体碰撞的真实反馈。也可以用于一些打斗场景，人物真实碰撞的效果。

使用方法（ComfyUI）

1. 下载 *.safetensors，放入 ComfyUI models/loras/
2. LoraLoader 加载，strength 建议 0.8~1.0
3. 用空间/物理语言 prompt 描述物体运动
