Regional prompting and per-region LoRA workflow for Krea 2, built on the ComfyUI-Krea2-Regional custom node pack — you need that installed for this workflow to load (clone it into custom_nodes/ and restart ComfyUI).
Paste a complete Ideogram-style JSON layout (high_level_description, background, style_description, per-object bbox) into the included text box — it's wired straight into the Regional Builder's import_json and is authoritative on every run, so a new JSON fully replaces the old scene.
Draw/edit regions on the Builder's own canvas, assign per-region LoRAs, and set global/base LoRAs separately.
Krea 2 Turbo sampling settings preserved (cfg 1, euler/simple, low step count) — not retuned.
Optional bypassable second passes: a Regional Detailer for whole-subject identity fixes, and an Impact Pack FaceDetailer for a stronger face-only redraw. Both off by default.
Fast 2x model-based upscale at the end (no slow tiled-diffusion re-render).
Requires: ComfyUI-Krea2-Regional custom node, Impact Pack + Impact Subpack (for the optional face pass), and an installed 4x upscale model (e.g. 4xUltrasharp).
