This is a super basic workflow with up to five reference images for the Nano Banana model. It uses the official ComfyUI Nano Banana node. Make sure you update to the latest ComfyUI version, and if that does not work, use the nightly build instead. Please note that you need API credits to use it, which can be purchased through your Comfy account.
The download includes the two test images I used in the example: the beautiful woman from my consistent character LoRA (https://civitai.com/models/1750662/photorealistic-ai-influencer-woman877-character-lora-sd15-or-sdxl-or-flux) and a sweater, so you can see how Nano Banana applies the sweater to her in the output.
