Built from the ground up over months of iteration, it gives you surgicalcontrol over how reference images influence your generations — from subtle texture injection tocomplete 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 theyinfluence 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 referencesystem for clean, artifact-free image conditioning- Strength Control — A denoise slider that actually works. 0.0 = no change, 1.0 = fullgeneration. 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 → SamplerReference 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 samemechanism the BFL API uses internally. No separate style models, no CLIP vision encoders, nobloat.### RequirementsModels (download and place in ComfyUI/models/):┌────────────────────────────────────┬───────────────────┐│ File │ Location │├────────────────────────────────────┼───────────────────┤│ flux-2-klein-9b-kv-fp8.safetensors │ diffusion_models/ │├────────────────────────────────────┼───────────────────┤│ qwen_3_8b_fp8mixed.safetensors │ text_encoders/ │├────────────────────────────────────┼───────────────────┤│ flux2-vae.safetensors │ vae/ │└────────────────────────────────────┴───────────────────┘Custom Nodes: (install via ComfyUI Manager)- rgthree-comfy (Power Lora Loader)- ComfyUI-Custom-Scripts (ShowText)- ComfyUI_Comfyroll_CustomNodes (CR Aspect Ratio)### How to use1. Load the workflow JSON (drag into ComfyUI)2. Load your base image in Ref 13. Optionally load a second reference in Ref 24. Write your prompt5. 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### LicenseThis workflow is free to use under the FLUX Non-Commercial License.Respect the model license terms.────────────────────────────────────────────────────────────────────────────────▶ YouTube — TripTrap Music<a target="_blank" rel="ugc" href="https://www.youtube.com/c/TripTrap1?sub_confirmation=1">https://www.youtube.com/c/TripTrap1?sub_confirmation=1</a>▶ Spotify — TripTrap Artist<a target="_blank" rel="ugc" href="https://open.spotify.com/artist/7vPfTIL4FweqDqTjcw4Bvr">https://open.spotify.com/artist/7vPfTIL4FweqDqTjcw4Bvr</a>▶ Apple Music — TripTrap<a target="_blank" rel="ugc" href="https://music.apple.com/us/artist/triptrap/1760346233">https://music.apple.com/us/artist/triptrap/1760346233</a>────────────────────────────────────────────────────────────────────────────────Built by TripTrap — glitch artist, experimental pop producer, and AI alchemist.Every image this workflow generates carries a frequency.
