Ref2Font FLUX.2 Klein 9B Fonts LoRA

# Ref2Font V3 — Contextual Font Atlas Generator (FLUX.2 Klein) Ref2Font V3 is a specialized LoRA for FLUX.2-klein-9B designed to expand a small reference into a full typography set. Give it a stylized sample of letters "Aa" for Latin or "Аа" for Cyrillic, and it will generate a consistent 1280x1280 font atlas including uppercase, lowercase, numbers, and punctuation. ### ✨ V3 Updates - Cyrillic Support: Full support for Russian. - Expanded Charset: Added " (double quote) and & (ampersand) to all atlases. - Updated Prompts: New specific prompts for different charsets to ensure mapping stability. - Straighter Letters: Improved alignment and reduced "jitter" in atlas generation. ### ✨ V2 Updates - Fixed Alignment: Letters no longer "jump" or dance; the baseline is much more stable. - Higher Resolution: Native resolution increased to 1280x1280 (previously 1024). - Improved Scripts: Updated pipeline for better vectorization (see ). --- ### 🚀 Quick Start (ComfyUI) 1. Input Image: Prepare a 1280x1280 image. It MUST be pure black & white (no gray, no shadows). 2. The "Aa" Rule: For best results, your input image should contain the English or Russian letters "A" and "a" in your desired style (see example images). These serve as the stylistic foundation for the rest of the atlas. 3. ⚠️ IMPORTANT: V3 Required Prompts To get the correct grid layout and character sequence, you must use these specific prompts depending on your target language: ### For Latin (English): Reference image must contain "Aa" A technical font atlas grid of the Latin charset: "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789!?.,;:-"&". The style is strictly derived from the reference image "Aa". ### For Cyrillic (Russian): Reference image must contain "Аа" A technical font atlas grid of the Cyrillic charset: "АБВГДЕЁЖЗИЙКЛМНОПРСТУФХЦЧШЩЪЫЬЭЮЯабвгдеёжзийклмнопрстуфхцчшщъыьэюя0123456789!?.,;:-"&". The style is strictly derived from the reference image "Аа". --- ### 🛠️ Required Technical Setup This LoRA is built for the Klein architecture. You will need these specific models in ComfyUI: * Base Model: FLUX.2 Klein Base 9B * Text Encoder: Qwen 3 8B * VAE: FLUX.2 VAE --- ### 📦 Post-Processing: Create your own .TTF The output is an image (atlas).
