Hi Megumint, tomorrow's update will add custom image endpoint compatability, which I believe won't work with ComfyUI, but I haven't tested. You can already use ComfyUI to generate room BGs and upload them manually to a character's folder, but tomorrow's update will also add the ability to manually upload inside of the UI. It's not true integration, but I hope that suffices for people who want to use their workflows to generate the BGs.
