Designed specifically for commercial imaging workflows, this adapter for FLUX.2 Klein 9B excels at handling complex occlusions (hands, veils, foreground objects) while seamlessly matching the exact color grading and directional lighting of your target scene.

✨ Why Choose This LoRA?

Standard face-swap methods often fail in professional environments by pasting faces over objects or introducing uncanny, plastic looks. SmartCharcterswap solves this by acting as an intelligent compositor:

Strictly High-End Realism: Engineered exclusively for practical photography and portrait retouching. It aggressively preserves realistic skin textures and structural anatomy while completely rejecting any cartoonish, illustrative, or overly-smoothed AI aesthetics.
Masterful Occlusion Handling: Understands depth perfectly. It seamlessly integrates the new identity behind occluding elements like fingers, hair, or microphones without breaking the image.
Perfect Lighting & Color Sync: Automatically adapts to the target's environment. If your base image is a high-contrast B&W portrait, the swapped identity will perfectly adopt those exact tonal values and shadows.
Identity Preservation: Maintains the distinct bone structure and unique micro-features of the source subject across diverse angles.

💻 Integration Guide

ComfyUI Setup

Download the .safetensors file.
Place it in your ComfyUI/models/loras/ directory.
Add the LoraLoader node into your workflow and use the trigger word jhuangswap at the beginning of your positive prompt.

Diffusers (Python)

python

from diffusers import Flux2Pipeline
import torch

pipe = Flux2Pipeline.from_pretrained(
    "black-forest-labs/FLUX.2-klein-base-9B",
    torch_dtype=torch.bfloat16
).to("cuda")

pipe.load_lora_weights("nhathoangfoto/Flux.2-Klein-9B-SmartCharcterswap", adapter_name="smartcharswap")
pipe.set_adapters(["smartcharswap"], adapter_weights=[0.85])

# For Distilled Model usage:
# result = pipe(prompt="jhuangswap, realistic portrait...", num_inference_steps=4, guidance_scale=1.0)
