⚠️ Optional Ollama Support Requirements

To use the Ollama-driven prompt generation features in this node, you need to:

• Install the Ollama server on your desired host.
  • Download for macOS or Windows
• Install the ComfyUI-Ollama node by Stav Sapir

Without these installed and running, the Ollama prompt outputs in this node will not function.

Credit for the ComfyUI-Ollama node goes to Stav Sapir (stavsap).

🔮 Future Plans

• Dynamic LLM integration for auto-generating character prompts
• Additional art styles (e.g., pixel art, steampunk, noir)
• Visual dropdowns for selecting features (e.g., races, classes, emotions)
