Krea2 Edit Source Chain

This is the small node in the pack that does exactly one thing: append one reference image to a chainable list for Krea 2 identity editing. Krea2IdentityEdit and the fusion node both take up to two images directly (image + image2). When you want a third, a fourth, or a dozen, you reach for this.

What it does

The node has one required input, image, plus an optional sources input whose tooltip is helpfully just "previous chain link." Feed one node's KREA2_SOURCES output into the next node's sources input, and each link appends its image to the growing list. The tail output wires into the sources input on Krea2IdentityEdit or Krea2MoodboardIdentityFusion, where those extra images land as reference frames 3..N after the two dedicated slots. There's no architecture limit on how long the chain gets.

If that sounds like the setup for a group photo of everyone you know, hold up. The edit LoRA (krea2_identity_edit by conradlocke, the community fine-tune this pack's editing path is built around) trained on one or two references. Push it to three and the identities start blending together - the model stops knowing whose face is whose and gives you a polite mush. The pack warns about this in the README, and the LoRA's own docs suggest the same thing. If you genuinely need multiple distinct people in one image, the working recipe is to chain edit passes instead: place person A in one edit, then run a second edit that adds person B from their own reference. Slow, but it keeps faces distinct.

What it's for, honestly

So the practical use for the chain is narrow: it's for cases where one subject is best represented by several shots - a few angles of the same face, say - and you want the edit to have more to work with. The author's framing is that 3+ refs blends identities, but blending several views of the same person is a different story and tends to help. Just don't expect it to solve multi-person composition.

Wiring

• image - the reference to append.
• sources - connect the previous link's KREA2_SOURCES here to extend the chain.
• Output - KREA2_SOURCES, which feeds sources on the Identity Edit / Fusion nodes (or extra_subjects on Krea2RedNode).

Installing

Same story as the rest of the pack - it ships with ComfyUI-Krea2Moodboard, no third-party node dependencies, GPL-3.0. Install the whole pack via ComfyUI Manager (search "Krea2Moodboard") or:

git clone https://github.com/RedNodeAI/ComfyUI-Krea2Moodboard ComfyUI/custom_nodes/ComfyUI-Krea2Moodboard

then restart ComfyUI. The pack has no requirements.txt; its only real prerequisites are ComfyUI's native Krea 2 support (0.25.0+), the qwen3vl_4b text encoder loaded with CLIPLoader type krea2, and the qwen_image_vae. For the actual editing you also need a krea2_edit LoRA at strength 1.0.

Keep the chain as light as the node is. One node per extra reference, and if you're past two references, ask yourself whether you're really after one face or several - the answer decides whether this node helps or makes things worse.
