<h1 id="promptwaffle-wf-fibo-2.0-character-lora-pipeline-v2">Promptwaffle WF — FIBO 2.0 Character LoRA Pipeline V2</h1>One character. Every angle.Turn your character references into a varied image dataset for your next character LoRA.This ComfyUI workflow brings together FIBO 2.0 Edit Turbo and Dev, four expanded prompt packs, structured JSON captions, automatic canvas selection, and a central control panel.Use Edit Turbo to build variations from your character references, or switch to Dev for standalone text-to-image generation. Create portraits, expressions, body views, poses, outfits, scenes, and lighting variations without rebuilding the graph.This workflow generates dataset images. LoRA training and dataset captioning are handled separately.Need help organizing and tagging your dataset?

Review and curate your generated images before training.<h2 id="edit-turbo-versus-dev">Edit Turbo versus Dev</h2>SettingEdit TurboDevMODE switchONOFFInputEnabled references and selected prompt packSeparate <code>dev_prompt</code> in P2Saved steps430CFG15Image referencesUsedBypassedPrompt-pack behaviorAdvances through the selected positive rowsRepeats the standalone Dev captionBoth modes use Euler, the simple scheduler, and denoise 1.0.The 110-row reference packs are designed for Edit Turbo.
