I ran the Flux Outpaint workflow that actually preserves the original composition.

I kept running into the same problem: generate a great image, realize the framing is too tight, extend it in ComfyUI, and the new pixels don't match the original style/lighting/subject.

Solved it with a two-stage approach:

  1. Masked expansion with high denoise on the new area only

  2. Light refinement pass on the seam with a 0.15 denoise blend

Here's the full workflow in action: https://youtu.be/ovfEBmyNj08

I'm using Promptus as the orchestration layer (visual interface, easier than raw ComfyUI for me), but the node logic works in standard ComfyUI too.

You can test the exact workflow here: https://login.promptus.ai/pwa_demo/#/cosyflows/116195233f2fa1ec5be4c0d12ce21799

The key insight: treating outpaint as a localized inpaint with asymmetric denoise values gives you way more control than a single "extend" operation.

Happy to share the .json if anyone wants to adapt it for their own use case.
