InstaSD - Style Selctor

If you came from Automatic1111, you probably had a saved styles list - named prompt+negative-prompt pairs like "cinematic" or "portrait". InstaPromptStyleSelector (yes, "Selctor" with a typo - that's the actual display name in the source) is the node that turns those into a ComfyUI dropdown. Pick a style, and it hands you the positive and negative strings ready to feed a CLIP Text Encode.

One style dropdown is the only input. The node reads a JSON file of styles and returns two strings:

• positive_string - the style's saved prompt.
• negative_string - the style's saved negative prompt.

Wire both into a CLIP Text Encode (positive to positive, negative to negative) and you've reproduced the A1111 behavior: a whole mood in one dropdown, plus your own prompt text concatenated after if you want.

Where do the styles come from? On startup the pack checks for a WebUI styles.csv (the exact format A1111 exports) and imports it into a styles.json for this node to read. That's the mechanism - and it's also where the first trap lives.

The path trap

The import path is hardcoded as /ComfyUI/styles/styles.csv - an absolute path at the filesystem root. On InstaSD's cloud workers, where /ComfyUI is the install location, that works fine. On a typical local Windows/Linux ComfyUI install, that directory almost certainly doesn't exist, so the import never runs, styles.json is never created, and the dropdown shows exactly one option: None.

If you want it working locally, drop a styles.csv (exported from A1111) at C:\ComfyUI\styles\styles.csv on Windows or /ComfyUI/styles/styles.csv on Linux - the exact path the code checks - and restart. Yes, the root-level /ComfyUI is deliberate in the code, not a mistake you can fix from the UI.

Install

cd ComfyUI/custom_nodes
git clone https://github.com/WaddingtonHoldings/ComfyUI-InstaSD

Restart ComfyUI, or install via ComfyUI Manager (search "InstaSD"). Dependencies are boto3, Pillow, requests, numpy. No models, no credentials - just your styles file.

Gotchas

• "None" only in the dropdown = the styles file wasn't found at /ComfyUI/styles/. Check the path before blaming the node.
• It's categorized under "WAS Suite/Text" in the source, so don't be confused when it shows up there in the menu rather than under InstaSD.
• Styles are prompt fragments, not magic. They're just strings; if a style looks weak, it's the text that's weak, and editing the CSV is all it takes to fix it.
