Amazing Upscale Node Workflow for DIT Model

This workflow is designed for simple logic amazing upscale nodes in the DIT model. It supports common applications for Flux, Hunyuan, and SD3. The workflow tiles the initial image into smaller pieces, uses an image-interrogator to extract prompts for each tile, and performs an accurate upscale process. This approach minimizes hallucinations and ensures proper condition handling.

We hope you enjoy using it!

Instructions

1. Image Tile Batch Node

This node cuts an image into pieces automatically based on your specified width and height. It also records the necessary information for further processing.

Parameter	Description
Width	The width of each tile.
Height	The height of each tile.
Image	The image to be tiled.

Image Tile Batch Node

2. Image Assembly Node

This node reassembles image tiles back into a complete image while preventing visible lines between the tiles. It operates in pixel mode.

Parameter	Description
Tiles	Input the tiled image batch. Replace individual tiles if needed.
Position	Paired with the Image Tile Batch Node.
Original Size	Paired with the Image Tile Batch Node.
Grid Size	Paired with the Image Tile Batch Node.
Padding	The padding value used to merge the image pieces.

3. Tile Image Size Node

This node calculates the resolution of each tile based on the original image dimensions and your specified width/height factors.

Parameter	Description
Width Factor	Divides the image width into equal parts.
Height Factor	Divides the image height into equal parts.

For example: A width factor of 2 and a height factor of 3 will divide the image into 6 equal tiles.

6. Condition Merge Node

This node merges all tiled conditions into one and prepares them for building the final image. It connects to the Coordinate Splitter Node and Cond to Batch Node.
