# LoRA Hook Keyframes From List 🎭🅐🅓
|
|
## Documentation
|
|
- Class name: ADE_LoraHookKeyframeFromStrengthList
|
|
- Category: Animate Diff 🎭🅐🅓/conditioning/schedule lora hooks
|
|
- Output node: False
|
|
- Repo Ref: https://github.com/Kosinkadink/ComfyUI-AnimateDiff-Evolved.git
|
|
|
|
此节点用于根据强度列表创建一系列LoRA挂钩关键帧，从而动态调整模型行为的多个步骤。它允许自定义关键帧属性，如强度和起始百分比，从而精确控制动画或转换过程。
|
|
|
|
## Input types
|
|
### Required
|
|
- strengths_float
|
|
- 指定序列中每个关键帧的强度。此参数可以接受单个浮点值或浮点值列表，允许灵活定义每个关键帧的强度。
|
|
- Comfy dtype: FLOAT
|
|
- Python dtype: Union[float, List[float]]
|
|
- start_percent
|
|
- 定义关键帧序列的起始百分比，设置动画或转换的起始点。
|
|
- Comfy dtype: FLOAT
|
|
- Python dtype: float
|
|
- end_percent
|
|
- 设置关键帧序列的结束百分比，标记动画或转换的终点。
|
|
- Comfy dtype: FLOAT
|
|
- Python dtype: float
|
|
- print_keyframes
|
|
- 一个布尔标志，启用时会将每个关键帧的详细信息打印到日志中，有助于调试和可视化关键帧序列。
|
|
- Comfy dtype: BOOLEAN
|
|
- Python dtype: bool
|
|
|
|
### Optional
|
|
- prev_hook_kf
|
|
- 一个可选参数，允许从前一个LoRA挂钩关键帧序列继续，启用序列之间的无缝过渡。
|
|
- Comfy dtype: LORA_HOOK_KEYFRAMES
|
|
- Python dtype: LoraHookKeyframeGroup
|
|
|
|
## Output types
|
|
- HOOK_KF
|
|
- Comfy dtype: LORA_HOOK_KEYFRAMES
|
|
- 返回一组LoRA挂钩关键帧，表示将应用于模型的一系列调整。
|
|
- Python dtype: LoraHookKeyframeGroup
|
|
|
|
## Usage tips
