PainterSampler for ComfyUI
ComfyUI 图生视频双模型串联采样器.本节点由抖音博主：绘画小子 制作
一个节点，一样画质。
One node, same quality.
**用单个 PainterSampler 替换两个 KSamplerAdvanced —— 显存、内存、生成效果完全一致。但是不需要再连那么多线，可以让你的工作流看起来更简洁 **
Replace two KSamplerAdvanced with a single PainterSampler — same VRAM, same RAM, same frames.But there's no need to create so many node connections – this will make your ComfyUI workflow look much cleaner.
