# Flux Union ControlNet
|
|
|
|
## Summary
|
|
|
|
Control-guided FLUX workflow using Union ControlNet, aimed at steering generation from structural inputs rather than relying only on prompting.
|
|
|
|
## Model Family
|
|
|
|
- `flux`
|
|
|
|
## Status
|
|
|
|
- `imported-only`
|
|
|
|
## Source
|
|
|
|
- Original repo page: <https://huggingface.co/StableDiffusionVN/Flux>
|
|
- Workflow file: <https://huggingface.co/StableDiffusionVN/Flux/resolve/main/ComfyUI_workflow/Flux_Union_Controlnet.json>
|
|
- Original publisher: `StableDiffusionVN`
|
|
- Date imported: `2026-08-08`
|
|
|
|
## Developer notes
|
|
|
|
- The publisher lists this as one of the included FLUX example workflows in the same repo as their other ComfyUI examples.
|
|
- Their README specifically points to `ComfyUI-eesahesNodes` for InstantX / Union ControlNet support.
|
|
- The workflow uses an `AIO_Preprocessor`, so the source expects an installed preprocessor stack as well, not just the loader node.
|
|
|
|
## Our notes
|
|
|
|
- This is one of the more practically valuable FLUX workflows because structural control tends to matter more than raw prompting once you actually want repeatability.
|
|
- Good candidate if you care about pose, edges, or scene layout staying closer to plan.
|
|
- In practice this is the workflow I would keep around when "make it obey the source shape" matters more than style exploration.
|
|
|
|
## Required custom nodes
|
|
|
|
- `ComfyUI-eesahesNodes` for `InstantX Flux Union ControlNet Loader`
|
|
- a ControlNet preprocessor pack that provides `AIO_Preprocessor`, commonly `comfyui_controlnet_aux`
|
|
|
|
## Built-in / core nodes used
|
|
|
|
- `CheckpointLoaderSimple`
|
|
- `ControlNetApplySD3`
|
|
- `CLIPTextEncode`
|
|
- `KSampler`
|
|
- `LoadImage`
|
|
- `VAEDecode`
|
|
|
|
## Notes
|
|
|
|
- Best use: structure-aware FLUX generation, especially when you have edge/depth/pose style guidance.
|
|
- This is more useful than plain text-to-image because it pushes FLUX into controlled generation rather than prompt-only luck.
