Inputs (19)

Name	Type	Default	Description
Tile_Fusion_Blend	FLOAT	0.500–1	Fusion margin with neighboring tiles (default: 0.5 = same value as Fusion Margin), lower values reduce risk of overlapping artifacts; higher values create more diffused blending but may risk visible seams.
Fusion_end	INT	0-50–0	Step number from the end after which fusion is skipped. For example, with 20 total steps, setting -10 means fusion runs only from step 1 to 10.
Fusion_conditioning	BOOLEAN	true	If true, fusion works with both conditioning and noise_mask; if false, it works only with noise_mask.
LanPaint	BOOLEAN	true	LanPaint: Universal Inpainting Sampler with Think Mode
Differential_Diffusion	BOOLEAN	true	Differential_Diffusion: ON OFF
Flux2_Tile_Color_Correction	BOOLEAN	true	Enable the selected Color Match correction for all refiner model types. If this Labs node is not connected, the refiner keeps this enabled by default.
Flux2_Sampler_Hook	BOOLEAN	false	OFF: use normal VAE encode plus ComfyUI Set Latent Noise Mask. ON: use the legacy/private Flux2 differential sampler hook.
Color & Structure Stabilizer	FLOAT	0.000–1	Uses a grid of anchor points to stabilize color and structure, reducing drift and preserving spatial coherence. Experimental feature.
Save_Tiles_in_Temp_Folder	BOOLEAN	false	For full-resolution in-process previews, tiles are saved to temp/TBG/compareTiles/
stitch_blending	COMBO	gpupyramid	2 options: gpupyramid, cpupyramid
max_upscale_size_segment	INT	2048256–4096	—
PID_Modelopt	MODEL		PiD models are auto-loaded from Hugging Face when available. This optional input lets you override that auto-selected PiD model with your own PiD model compatible with the main model and VAE used by the refiner.
ColorMatch_Debugopt	tbg_colormatch_debug		Optional developer pipe for isolating individual ETUR ColorMatch stages.
Custom_Sigmas_!DENOISE=1opt	SIGMAS		Insert your full custom sigma noise curve (not denoised), as denoising is performed per tile by the node.
Sampleropt	SAMPLER		Plug in a custom sampler or ClownSampler here to override the sampler selected in the refiner node.
Ideogram4_Guideropt	GUIDER		—
cropped_positiveopt	CONDITIONING		Optional full-image positive conditioning for crop-aware tile sampling. Provide conditioning for the full reference/source image; ETUR crops the matching region for each tile and appends it to the tile's normal positive prompt/reference conditioning. It does not overwrite the normal conditioning. If you do not want to use the ETUR ControlNet pipe, you can use cropped conditioning in a similar way to Ultimate SD Upscale, including conditioning that already contains ReferenceLatent inputs.
cropped_negativeopt	CONDITIONING		Optional full-image negative conditioning for crop-aware tile sampling. Provide conditioning for the full reference/source image; ETUR crops the matching region for each tile and appends it to the tile's normal negative conditioning. It does not overwrite the normal conditioning. If you do not want to use the ETUR ControlNet pipe, you can use cropped conditioning in a similar way to Ultimate SD Upscale, including conditioning that already contains ReferenceLatent inputs.
Segment_Background_Harmonizationopt	BOOLEAN	true	Low-frequency color/tint correction for generated segment surroundings. Protects the object/core mask while matching the segment background to the finished tile-only canvas.
