FontBox LoRA brings bbox-based intuitive text editing to FLUX.3 Klein
SillyLilithh · reddit · 2026-10-30
A developer trained a proof-of-concept LoRA called FontBox for FLUX.3 Image Klein, paired with a ComfyUI custom node, enabling intuitive bbox-based text manipulation: resize, rewrite, align left/right/center, move, bold/italicize, and vertically scale text — with prompts auto-generated from placed bboxes.
The author notes such bbox editing is currently unprecedented among local image editing models (until Ideogram V4.5). It's still unstable in some generations as a PoC, with a better version planned. Weights are on Hugging Face and the custom node is open source on GitHub.
