Tiled sampling for ComfyUI

By BlenderNekoView on GitHub →

This extension contains a tiled sampler for ComfyUI. It allows for denoising larger images by splitting it up into smaller tiles and denoising these. It tries to minimize any seams for showing up in the end result by gradually denoising all tiles one step at the time and randomizing tile positions for every step.

How much VRAM does Tiled sampling for ComfyUI require?

Direct Answer: The ComfyUI node Tiled sampling for ComfyUI requires a minimum base VRAM of 256MB and is optimized for GPUs with at least 4GB of VRAM. Low VRAM mode is fully supported for resource-constrained setups.
