Props

What Are Props?

Props are recurring visual objects in your story — weapons, vehicles, locations, artifacts, furniture, anything physical. Define a prop once and the AI renders it consistently across every panel it appears in.

Props vs Characters

Characters are sentient beings. Props are everything else — objects, items, places, and things. If something physical recurs in your story and visual consistency matters (a specific sword, a spaceship, a throne room), make it a prop.

Examples of good props:

  • A spaceship with a specific shape and markings
  • An enchanted sword with distinctive runes
  • A recurring location — the villain's lair, the tavern, the market square
  • A unique vehicle, robot, creature, or artifact
  • Any object that must look the same every time it appears

The prop reference sheet

Like characters, every prop gets a reference sheet generated automatically after creation. The sheet shows the prop from multiple angles — front, side, and 3/4 perspective — on a neutral background.

The reference sheet is rendered in your story's chosen art style. Whenever you mention a prop by name in a panel, its sheet is passed to the image AI as a direct visual reference — the same mechanism that keeps character faces consistent.

How it works

When you mention a prop by name in a panel description, YarnSaga:

  1. Detects the name during scene validation and matches it to the prop's record
  2. Injects the prop's reference sheet as a visual reference into the image prompt
  3. Instructs the AI to reproduce the prop exactly — same shape, colors, markings, and details

This means "The Starship Nomad" in panel 3 will look identical to "The Starship Nomad" in panel 17, even if the lighting, angle, and scene composition are completely different.
