Using a reference image (person, object) with Krea2 is something that needs a bit more than just adding a reference image and that's it.

So, a simple workflow, that uses 1 reference image and it's called to several separate prompts (or one).

Each plate from Multy_prompts (custom node https://github.com/JDJoe/ComfyUI-Multy_prompts) is an edit of the same reference photo. The photo holds the person. The plate says what to add.

Download the .json and you are good to go. Make sure you custom nodes installed!

NB! You must have krea2_identity_edit_v1_2.safetensors or later version.
Use what ever other LoRA's you like.
