HY-World Qwen Pano Prompt

The Qwen Pano sub-pipeline in this pack expands a normal image outward into a full 360° equirectangular panorama. And like most prompt-driven image work, the difference between a seamless 360 and a visible seam is partly the prompt. HYWorld2 Qwen Pano Prompt is the tiny node that builds those prompts - it wraps your scene description in the official prompt template the Qwen pano pipeline was tuned with, plus its fixed negative prompt, and hands you the strings ready to plug into the generator.

Honestly, this node exists so you don't have to memorize the template. That's its whole job, and it does it well.

How it works

You give it a scene_prompt (default "a clean bright indoor scene") and it returns two strings:

• positive_prompt - with use_official_prompt on (default), it wraps your text in the official ERP (equirectangular panorama) expansion template: "Create a ERP panoramic expansion of the provided image. Preserve the original style, lighting, and fine details seamlessly throughout the extended areas, extend according to: [your prompt] 8k UHD, masterpiece, razor-sharp details."
• negative_prompt - starts from the pipeline's fixed negative list (low resolution, blurry, distorted structure, object fusion, cars, "tree leaves at the top edge of the image" - a nicely specific failure mode for pano edges), then appends anything you put in the optional negative_prompt field.

If you flip use_official_prompt off, it just passes your raw text through with no template and no stock negatives - useful when you've written your own phrasing and don't want the template fighting it.

Inputs and outputs

scene_prompt (required), use_official_prompt (required, default true), optional negative_prompt. Outputs are positive_prompt and negative_prompt, both strings, both meant to wire directly into HYWorld2 Qwen Pano Generate (or any text-encoder node).

Install & troubleshooting

Same pack install as everything else: ComfyUI Manager (search HY-World 2.0) or clone + pip install -r requirements.txt + python install.py. There are no model downloads here - it's pure string building.

The only real trap is subtle: the template says "extend according to", so the scene_prompt should describe the continuation, not restate the whole image. Write "a dusty bookshelf continuing to the right" rather than "a room with a bookshelf". And if your output panoramas keep getting rejected by weird artifacts, check the negatives - the stock list is tuned for this task, so keep it unless you're deliberately experimenting. That's about the entire failure surface of a string-formatter, which is a nice break from the rest of this pack.
