traumakom Prompt Generator – ComfyUI Node

A powerful custom node for ComfyUI that generates rich, dynamic prompts based on modular JSON worlds — with color realm control (RGB / CMYK), LoRA triggers, optional AI-based prompt enhancement, and a modular Identity Mixer to build consistent characters from reusable traits.

🌟 Features

PromptCreator Core

• 🔮 Dynamic prompt generation from modular JSON worlds
• 🎨 COLOR_REALM support for RGB / CMYK palette-driven aesthetics
• 🧩 LoRA trigger integration (e.g., Realistic, Detailed Hands)
• 🧠 Optional AI enhancer (OpenAI / Cohere / Gemini / Ollama / llama.cpp) to rewrite or enrich prompts
• 📁 Reads world data from /JSON_DATA
• 🧪 Debug messages + error handling for smoother workflows
• 🔄 Reload JSON worlds without restarting ComfyUI

✅ Identity Mixer (NEW)

• 🧬 Modular identity generation via reusable traits
• ♻️ Trait library (TRAITS) + curated presets (PRESETS)
• 🎲 Randomized or fixed identity attributes
• 📴 Optional ethnicity exclusion (None)
• 🧷 Identity signature output for dataset consistency
• 🧼 Explicit trait syntax (e.g. lavender hair, emerald eyes) to avoid semantic bleed
