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.
