I made a workflow to make consistent character using IP Adapter

The way it work is easy :

Choose a pose image (Note The final result image size will be base on the pose image size)

Choose a background image : Will fill the background of the character or 2 character

Choose a Face Image for the character

Choose a Body Image for the character

Use Positive prompt for Detail : Ex : You want to change the hair, it good to also describe the person you want to make.. i made the picture you will see using :

Pose : 1 man, long blond hair, silver armor

Neg : Blurry Somme Embedding
