Hello there and thanks for checking out this workflow!

Purpose

Originally built to provide a simple and powerful Outpainting workflow—making use of the Flux Tools Fill model.
This workflow now features dedicated sections for Outpainting, Inpainting using the ACE LoRAs as well as regular Inpainting, all in one place!

As usual the workflow is accompanied by many notes explaining nodes used and their settings, personal recommendations and observations.

Features

  • LoRA support

  • Detail Daemon sampling to add detail

  • Florence 2 prompt assistance → Outpainting

  • Custom Padding presets → Outpainting

  • Batch handlingInpainting

  • Image Filter to cherry pick → Inpainting

  • Installation and download guide for models and nodes

Custom Nodes used

All of which can be installed through the ComfyUI-Manager

Troubleshooting

  1. If nodes show up red (failing to load), check the 'Install Missing Custom Nodes' tab of the ComfyUI Manager for the missing node packs and install them.

  2. Please check if all custom node packs load properly after installing, i.e. no (IMPORT FAILED) messages next to any of them in the console upon ComfyUI startup.

  3. Always reload/drag'n'drop the original, downloaded workflow file into ComfyUI to reload an intact version of the workflow.

    → The last opened workflow that appears on startup shows a cached version of the workflow, "remembering" group nodes that failed due to missing nodes as failed, keeping them broken even after having everything installed correctly.


Thanks

The workflow would not be possible as is without these custom node packs. If you want to support the custom node creators, give them a ⭐ on their github repos! Thank you!
