Set Design
In traditional production you scout locations, build sets, and coordinate logistics. In ACT3 AI, every environment is virtual — you create it, modify it, and place it into your scenes without permits, travel, or construction budgets.
The craft decisions are the same. What does the space look like? What does it say about the scene?
Your work in ACT3 AI
Sets in ACT3 AI are reusable environments attached to scenes. You create a set once and use it across as many shots and scenes as it appears in. Any change to the set updates every shot that uses it.
What you'll do here
Tasks are listed most common first.
Browse and choose a set from the library
The Sets directory has a searchable library of pre-built environments. Search by keyword, filter by location type (interior, exterior, urban, natural), and preview before assigning.
→ How to browse and assign a set
Create a new set from a text description
Type a natural language description — "1940s police interrogation room with a single overhead light" — and the AI generates a set. You refine from there.

Upload a reference image as a 2D set
If you have a location photo, a film still, or a concept image that captures the look you want, upload it as a 2D background. ACT3 AI aligns the ground plane so you can place 3D characters into it correctly.

Use procedural city or building generation
For large-scale urban environments or repeating interior spaces, use the "City on Rails" or "Building on Rails" generators. Define the building types and style; ACT3 AI generates the geometry.

Place characters and cameras in a set
The top-down canvas gives you a bird's-eye view of the set. Drag character icons to position them, draw movement paths as splines, and place cameras with visible sight-line cones.
→ How to use the top-down set editor
Add props and environmental details
Place individual "AI Wonder Objects" — specific props, creatures, or background elements — at precise positions within a set to customize it per scene.
Link a set to multiple scenes
Once you've built a set, attach it to every scene that takes place there. The set's geometry, lighting setup, and character placement reference all carry through.
Import a 3D Blender set
If you or a VFX artist are building custom 3D environments in Blender, sync them directly into ACT3 AI through the Blender Sync workflow.
