FLUX 3 Image Klein multi-reference workflow. Feed one to ten reference images and tell the model which one owns the character, which one owns the outfit and which one owns the scene.
Main features:
- Built on the distilled FLUX 3 Image Klein checkpoint (flux3_image_klein_sd_int8_convrot + qwen3vl_4b text encoder + flux2 VAE)
- ReferenceMultiLatent packs up to 10 reference images into a single conditioning tensor; reference them in the caption as ref_image_0 through ref_image_9
- 16 steps, no classifier-free guidance, euler/simple, denoise 1.0
- ConditioningZeroOut lets you disable a reference slot without deleting its image, which makes A/B of reference sets quick
- ImageCompare renders candidates side by side so you can judge drift across reference counts
Suggested workflow:
1. Load 1 to 10 reference images into the ReferenceMultiLatent node. Start with 1-2: accuracy degrades noticeably past 4 references.
2. Assign jobs in the caption explicitly, e.g. "ref_image_0 is the character, ref_image_1 is the outfit, ref_image_2 is the background".
3. Run, compare with ImageCompare, and increase the reference count only when a slot is genuinely needed.
Dependencies:
- flux3_image_klein_sd_int8_convrot.safetensors (distilled UNET)
- qwen3vl_4b_int8_convrot.safetensors (text encoder / CLIP)
- flux2-vae.safetensors (VAE)
- ReferenceMultiLatent, ImageCompare (custom nodes)
