Apply the design from Reference Image 1 onto objects in Reference Image 2.

Unbypass (CTRL-B) the ReferenceLatent nodes to give ref images.

If you want to add more reference images, you can add multiple reference images by following the pattern.

If you don't want any reference image, just select all ReferenceLatent nodes and then use CTRL-B to bypass them, turning the workflow into a Text to Image workflow.
