FLUX.2 Kontext Img2Img — Multi-Reference + Strength-Guidance Image Editing Workflow by TripTrap

Description
This workflow turns FLUX.2's native Kontext architecture into a fully-featured image-to-image
editing powerhouse. Built from the ground up over months of iteration, it gives you surgical
control over how reference images influence your generations — from subtle texture injection to
complete stylistic transformation.
Whether you're editing album art, refining character designs, or exploring glitch aesthetics,
this workflow lets you feed in up to 2 reference images and dial in exactly how much they
influence the output with a single strength slider.
### What makes this different
- FLUX.2 Native — This isn't a hack. It uses FLUX.2 klein 9B KV-FP8's built-in Kontext reference
system for clean, artifact-free image conditioning
- Strength Control — A denoise slider that actually works. 0.0 = no change, 1.0 = full
generation. No cryptic parameters.
- Multi-Reference — Chain up to 6 reference images through the Kontext system for composite influences
- Prompt Engineering — Built-in text concatenation for complex multi-source prompts
- VRAM Safe — Auto-scales images to 0.5MP before encoding, preventing accidental OOM crashes
- 4-Step Generation — Optimized for FLUX.2's distilled inference. Blazing fast.
### How it works
```
Reference Image → Scale → VAE Encode ──┐
├──→ ReferenceLatent Chain → Conditioning → Sampler
Reference Image → Scale → VAE Encode ──┘
↑
Prompt → Text Concat → CLIP Encode → Flux Guidance ──────────┘
```
The reference images are injected directly into FLUX.2's Kontext conditioning system — the same
mechanism the BFL API uses internally. No separate style models, no CLIP vision encoders, no
bloat.

Custom Nodes: (install via ComfyUI Manager)
- rgthree-comfy (Power Lora Loader)
- ComfyUI-Custom-Scripts (ShowText)
- ComfyUI_Comfyroll_CustomNodes (CR Aspect Ratio)
### How to use
1. Load the workflow JSON (drag into ComfyUI)
2. Load your base image in Ref 1
3. Optionally load a second reference in Ref 2
4. Write your prompt
5. Set denoise (0.65 is a good starting point)
6. Queue it
### Tips
- 0.5–0.65 denoise: Subtle edits, preserves composition
- 0.65–0.8 denoise: Balanced changes with strong reference influence
- 0.8–1.0 denoise: Heavy transformation, prompt dominates
- Use 4 steps for speed, or up to 8 for more refinement
- Keep images under 1MP for best performance
