ComfyUI Ultimate SD Upscale FLS LLLite

ComfyUI custom nodes that extend the Ultimate SD Upscale tile workflow with an FLS-style sampling path and an optional Anima Tile/Repair ControlNet-LLLite conditioning step.

This repository contains only the custom node code. It does not include workflows, checkpoints, LoRAs, ControlNet/LLLite weights, upscale models, generated images, API keys, or environment-specific configuration.

Nodes

The package registers two nodes:

• UltimateSDUpscaleFLS
  • Display name: Ultimate SD Upscale (FLS Accelerated)
  • Category: image/upscaling
• UltimateSDUpscaleFLSLLLite
  • Display name: Ultimate SD Upscale (FLS + LLLite Tile Repair)
  • Category: image/upscaling

Both nodes keep the usual Ultimate SD Upscale inputs for image, model, conditioning, VAE, upscale model, seed, sampler, scheduler, denoise, tile size, padding, mask blur, seam fix, and tiled decode options.

Extra Controls

FLS controls:

• fovea_strength
• sharpness
• mask_inertia

LLLite controls, only on UltimateSDUpscaleFLSLLLite:

• lllite_model_name
• lllite_strength
• lllite_start_percent
• lllite_end_percent

lllite_model_name is read from ComfyUI's controlnet model folder.

Installation

Clone into ComfyUI/custom_nodes:

cd ComfyUI/custom_nodes
git clone https://github.com/Lebensignal/ComfyUI-UltimateSDUpscale-FLS-LLLite.git

Restart ComfyUI.

On first import, this package creates repositories/ultimate_sd_upscale and downloads the original Coyote-A Ultimate SD Upscale script if it is missing.

For offline installation, manually place the contents of:

https://github.com/Coyote-A/ultimate-upscale-for-automatic1111

inside:

ComfyUI/custom_nodes/ComfyUI-UltimateSDUpscale-FLS-LLLite/repositories/ultimate_sd_upscale

Optional LLLite Setup

UltimateSDUpscaleFLSLLLite expects a compatible Anima LLLite apply node to be available in:

ComfyUI/custom_nodes/ComfyUI-Anima-LLLite

Place compatible LLLite weights in:

ComfyUI/models/controlnet

For the public Anima Tile/Repair LLLite model, see:

• https://huggingface.co/LAXMAYDAY/Anima_Tile_and_Repair_ControlNet-LLLite/tree/main
• https://civitai.red/models/2708551/anima-tile-and-repair-controlnet-lllite

Notes

• The FLS node can be used without the optional LLLite dependency.
• The LLLite node requires the separate LLLite apply node and compatible model weights.
• No model weights are redistributed here.
• examples/anima-fls-lllite-basic contains a placeholder API-format workflow that shows one possible Anima-style graph. Replace all placeholder model and LoRA filenames before use.
