Props

A Prop is an asset for a specific object in your story. Unlike Actors, Props have no wardrobe variants — each Prop is a single canonical image. If an object matters enough to appear in your script by name, give it a Prop Node so it looks the same everywhere it shows up.

Props live on the Flow canvas alongside Actors and Sets. They pass through the same approval workflow and feed the same storyboard pipeline downstream.

Generate a Prop

1. Open the Prop Node. PrePrompt creates a Prop Node for every named object surfaced during Script Node analysis. You can also add one manually from the canvas.

2. Describe the object. Size, material, era, and style matter most. “A 19th-century cavalry sabre, worn leather-wrapped grip, slight rust on the blade” generates a very different image than “a sword.”

3. Pick a style and aspect ratio. Style inherits from the project by default. Most Props look best on a neutral background so they read clearly when placed into a scene.

4. Generate. The hero image renders in a few seconds.

5. Approve. Mark the Prop approved so it can pass the Director Review Board and be used by the Storyboard Node.

One image, many scenes

A Prop’s single hero image is used as a visual reference across every storyboard frame that features it. You don’t need variants — the Storyboard Node re-interprets the Prop in context (different angles, lighting, positions) using the hero as ground truth.

Approve, reject, reshot

Props move through the same three states as every other asset:

• Pending — awaiting review.
• Approved — locked in, ready to propagate downstream.
• Rejected — blocked from use until regenerated.

To reshot, adjust the description and generate again from the Prop Node. A reshot rebuilds every storyboard frame that used this Prop on the next storyboard run. Use reshot when the object design is wrong; use a single-frame regenerate when a specific frame misplaces or misrenders an otherwise correct Prop.

Tips for sharp Props

Be specific about size

“A pocket-sized silver locket” and “a dinner-plate-sized medallion” are very different images. Scale is hard to infer from a description alone.

Name the material

Brass, oak, worn leather, brushed steel, pale ceramic. Material choices drive texture and lighting response.

Anchor it to an era

“Early 1970s rotary phone, avocado green.” “Victorian brass pocket watch.” Period language narrows the design space fast.

Describe the condition

A brand-new object and a beaten-up one tell different stories. “Chipped,” “pristine,” “sun-faded,” “recently polished” are all useful words.

FAQ

Why don’t Props have wardrobe variants? Objects don’t change identity the way characters do. If you need meaningfully different versions of the same object — a pristine sword and the same sword shattered in act three — create two separate Props and reference each where appropriate.

Do I need a Prop Node for every object in my script? No. Only for objects whose visual consistency matters across frames. A generic coffee cup that appears once in a wide shot doesn’t need its own node. A signature weapon or a plot-critical letter does.

Can I upload an existing reference image for a Prop? Yes. Drag an image onto the Prop Node and PrePrompt uses it as the hero reference instead of generating from scratch. Useful when you have product photography, concept art, or a real-world object you want to match.

What happens if I reshot a Prop after building the storyboard? Every frame that used that Prop rebuilds on the next storyboard run. This is the whole point of the reshot workflow — fix the object once, and every appearance updates automatically.

What if my Prop looks different in every frame? The Prop was probably not approved, or the storyboard ran before the new hero image was set. Confirm the Prop is approved, then regenerate the affected frames.

Are Props reusable across projects? Assets live inside the project they were created in. Cross-project reuse is on the roadmap.
