+## Description
+
+# Krea 2 Regional Multi-LoRA — Multi-Character + Bounding-Box Layout Control
+
+Put **multiple character LoRAs in a single Krea 2 image**, each one locked to its own bounding box — no bleed, no merged faces, no averaging. And it's not just for LoRAs: draw and describe boxes for **objects, props, backgrounds, and extra subjects** too, exactly like Ideogram 4's bounding-box prompting.
+
+## What it does
+
+Normal LoRA loading applies everywhere, so two character LoRAs smear into each other. This node injects each LoRA's effect **only into the image tokens inside its box, at forward time** — outside the box the effect is multiplied by zero. It's a hard spatial guarantee, not an attention-bias nudge the model can ignore.
+
+Pair it with an Ideogram 4-style prompt builder and every box does double duty:
+
+- **Every box** places its described content via Krea 2's Qwen3-VL text encoder (a table, a neon sign, a dog on the left — Krea 2 honors the placement).
+
+- **LoRA boxes** additionally lock in a specific trained identity on top of that placement.
+
+Sketch the whole scene as boxes, describe each one, and drop LoRAs into the boxes that need a precise face. Objects and characters, all placed by the same boxes.
+
+## Features
+
+- Unlimited regions — 2 characters or 10, add a row per box
+
+- Region rows auto-sync to the boxes you draw (draw a box, a row appears)
+
+- Hard per-region LoRA masking (activation-delta injection)
+
+- Bounding-box layout control for non-LoRA elements too
+
+- fp8-safe — never touches quantized model weights
+
+- Runs at Krea 2's native CFG 1
+
+## Requirements
+
+- ComfyUI with Krea 2 support (recent build)
+
+- Models: `krea2_turbo_bf16` (UNet), `qwen3vl_4b_bf16` (CLIP, type krea2), `qwen_image_vae` (VAE)
+
+- Custom node: **ComfyUI-Krea2-Regional-MultiLoRA** (this workflow's node)
+
+- ComfyUI-KJNodes (for the box-drawing prompt builder)
+
+- Character LoRAs trained against Krea 2 (e.g. via ai-toolkit)
+
+## How to use
+
+1. Write your scene prompt in the box builder (setting/lighting/camera — not the characters).
+
+2. Draw one box per element, in order. Rows appear automatically in the LoRA node.
+
+3. Assign a LoRA to each character box; leave object/scenery boxes as plain descriptions.
+
+4. Sampler: euler / bong\_tangent / 8–12 steps / CFG 1.
+
+5. Queue.
+
+## Tips
+
+- Keep character boxes from overlapping to avoid bleed.
+
+- If seams show, raise `seam_feather` a touch (0.12–0.15).
+
+- Row order must match box order (row 1 = first box drawn).
+
+- Character LoRAs must be Krea 2-trained — FLUX/SDXL LoRAs load but look wrong.
