ComfyUI-RPG-Characters

A custom node for ComfyUI that generates stylized prompts for RPG characters. This node outputs both standard prompt formats and enhanced Ollama-style descriptive prompts ideal for extreme close-up portraits.

✅ Compatible with Stable Diffusion, SDXL, Flux, and any model that uses structured prompts.

The generator supports both classic AD&D / Fantasy and Sci-Fi / Cyberpunk character creation, with expanded classes, clothing styles, scenes, and art styles. Sci-Fi characters can be created without augmentations, allowing fully augment-free characters as well as cybernetic ones.
