AI-generated commentary

AI-generated explanation based on source and configuration details. Suggestions are clearly labeled.

Purpose

  • Foton's Workflow with ControlNet upscale is for generating SDXL, Pony, or Illustrious images with ControlNet tile upscaling instead of Ultimate SD; it takes generation, HiRes, and face-detail settings and can save images compatible with Civitai when Save Images With Metadata ‌‌‍‍

Flow

  • Generation settings are combined in one subgraph, with upscale controls in the HiRes subgraph and face-detail options in the face-detail step.

Inputs and outputs

  • Controls include the initial upscale model, ControlNet tile checkpoint, tile batch size, blend factor, upscale size, and denoise.

  • Face detailing can use custom positive and negative prompts, with additional nodes available for different LoRAs during that step.

Setup

  • Install Save Images With Metadata Universal Extension manually, then run Rules Scanner Subgraph after installation or after changing nodes in ComfyUI so the metadata saver works properly.

    Suggestion · not verified

  • Place the ControlNet models in ComfyUI/models/controlnet.

Dependencies

  • The listed node packs are comfyui-impact-pack, ComfyUI-TiledDiffusion, comfyui-impact-subpack, and skimmed_cfg.

  • Before use, check for these exact files: GOBOLightingILL.safetensors, glinty_v1.safetensors, TTPLANET_Controlnet_Tile_realistic_v2_fp16.safetensors, remacri_original.safetensors, and bbox/face_yolov8m.pt.

    Suggestion · not verified

  • Check your ComfyUI installation for node packs named exactly ComfyMath and SaveImageWithMetaDataUniversal.

    Suggestion · not verified

Configuration

  • To disable CFG Skimming, turn off enable_skimming and set CFG to the checkpoint's recommended values.

    Suggestion · not verified

  • For 3–4× upscaling, use denoise 0.2 or lower; for lower VRAM use, set tile_batch_size and Tiled Diffusion batch size to 1 and VAE Decode tile size to 512.

    Suggestion · not verified

  • For face detailing, set Use custom prompt to true to enter positive and negative prompts; increase feather if visible edges appear around faces.

    Suggestion · not verified

Cautions

  • No license is listed for this workflow, so verify the applicable usage terms before using it.

    Suggestion

  • Changing overlap in the 512×512 low-VRAM setup has not been tested.
