Start comfyui

add Tiled KSampler Node and use like KSampler

when tiling = 1 it will tile

when tiling = 0 it will behave like a normal KSampler

add Asymmetric Tiled KSampler Node and use like KSampler

when tileX = 1 it will tile in the X direction

when tileY = 1 it will tile in the Y direction

You'll need to use this when decoding the image, otherwise you'll get bleeding around the edges. It basically applies the Circular padding during decoding as well.

Based off WAS Studio

using the example for tiling from Automatic1111
