Character Cloning Plagues Multi-Reference Scenes in H3 Video Generation
itchplease · reddit · 2026-09-11
A video creator reports frequent "character cloning" in H3 when using multiple character references in one scene: with a protagonist walking a ship deck and three sailors each having their own reference image and task, the model often clones one of them—same face, same clothes, sometimes even similar movements.
Explicit prompting about which reference belongs to whom and stating they must be distinct individuals hasn't fixed it. The poster is asking the community for prompting tricks, reference setup, RefMods, or workflow techniques that keep multiple characters distinct in the same shot.
