✨ FLUX — Outpaint — Simple Workflow
A clean, all-in-one FLUX Outpaint workflow built entirely with the UmeAiRT Toolkit for ComfyUI. Only 8 nodes . No spaghetti wires. Just load your model, write your prompt, and hit generate.
⚠️ IMPORTANT — Nodes 2.0 Required
This workflow is built for the Nodes 2.0 (Vue) interface of ComfyUI. If you don't enable it, the workflow may have display problems.
How to activate Nodes 2.0:
Open ComfyUI
Go to Settings (⚙️ icon, bottom-left)
Find "Use Nodes V2 (Vue)" and toggle it ON
AI-generated commentary
AI-generated explanation based on source and configuration details. Suggestions are clearly labeled.
The 【FLUX】OUTPAINT workflow is for text-to-image generation and outpainting in ComfyUI. It takes a loaded model and written prompt, then produces saved images with optional SeedVR2 tiled upscaling and embedded generation parameters.
It combines image generation, outpainting, optional SeedVR2 tiled upscaling, metadata embedding, and LoRA controls in one ComfyUI workflow.
You provide a model and text prompt, with optional LoRA modules controlled through the workflow.
The workflow saves images with generation parameters embedded; SeedVR2 tiled upscaling can be switched on or off.
In ComfyUI, enable “Use Nodes V2 (Vue),” refresh the page, and load the workflow.
Install ComfyUI-UmeAiRT-Toolkit through ComfyUI Manager by searching “UmeAiRT,” or use the UmeAiRT Auto-Installer.
The named items are ComfyUI-UmeAiRT-Toolkit, 4x_NMKD-Siax_200k.pth, and FLUX/Fill.
4x_NMKD-Siax_200k.pth is listed as an upscaler, and FLUX/Fill is listed as a checkpoint.
Before use, verify that ComfyUI-UmeAiRT-Toolkit and FLUX/Fill are available in your setup.
Suggestion · not verified
Three LoRA slots have individual on/off toggles and strength controls, and additional LoRA modules can be connected.
Manual setup lists `flux1-fill-dev-fp8.safetensors` or `flux1-fill-dev-fp16.safetensors`, GGUF model and CLIP choices from Q3 through Q8, `clip_l.safetensors`, text encoder options, and `ae.safetensors` as the VAE.
The workflow requires ComfyUI’s Nodes 2.0 (Vue); without it, display problems may occur.
SeedVR2 tiled upscaling is optional, and the description says it is slower than a classic upscaler.

🎯 Features
Text-to-Image generation
Automatic download of models in auto version
Built-in SeedVR2 upscaler — high-quality tiled upscaling (toggleable on/off) Slower than a classic upscaler, but significantly better quality
Full metadata embedding — your images are saved with all generation parameters, ready for online publishing and remixing
3 LoRA slots — with individual on/off toggles and strength control and you can connect as many other lora modules to each other for as many LoRA as you want.
📦 Custom Node Required
Only one custom node to install:
👉 ComfyUI-UmeAiRT-Toolkit
Install via ComfyUI Manager (search "UmeAiRT") or use the UmeAiRT Auto-Installer . The Toolkit packages everything internally — upscaler, face detailer, metadata saver. No other custom nodes needed.
