Lock the seed for consistent characters

The prompt

Reuse the same seed number across every shot in a sequence — it keeps a character face, outfit, and lighting consistent across multiple generations instead of drifting shot to shot.

Expected result

The same character face, outfit, and lighting held consistent across every generation that reuses the seed, instead of drifting between shots.

Why it works

Most diffusion models are deterministic given the same seed and prompt, so locking the seed is what actually makes repeatable characters possible.
