If you want negative prompt to have an effect, use NAG:<a target="_blank" rel="ugc" href="https://github.com/ChenDarYen/ComfyUI-NAG">https://github.com/ChenDarYen/ComfyUI-NAG</a>or NAGuidance node<a target="_blank" rel="ugc" href="https://github.com/Comfy-Org/embedded-docs/blob/main/comfyui_embedded_docs/docs/NAGuidance/en.md">https://github.com/Comfy-Org/embedded-docs/blob/main/comfyui_embedded_docs/docs/NAGuidance/en.md</a>but keep in mind that it will decrease generation speeds.optimal values for Normalized Attention Guidance node:nag_scale=3.0nag_alpha=0.25nag_tau=1.0nag_sigma_end=0.75
