What is the 3D Builder plugin?

It is the Topview 3D Builder plugin for agents. In GPT, Claude, or another agent, you ask for a scene. The plugin builds an editable 3D stage, then you can set the camera and generate.

Which agents can use it?

The plugin is for GPT, Claude, and other agents. On this page you install it in Codex, or from the GitHub source, so the agent can call 3D Builder.

How do I add it to GPT?

Use the Codex install on this page. Add the marketplace, add the plugin, then restart and ask it to build a scene. You can also download the source on GitHub.

Can I use it in Claude?

Yes. The plugin is meant to run inside Claude and other agents, the same way it runs in GPT. Install it from the steps on this page, then ask Claude to build the scene.

Can the agent build a scene from text or a reference image?

Yes. In the chat, describe the scene or pass a storyboard, concept frame, or still. A reference helps later messages keep the same space, composition, and style.

Can I change the scene after the agent builds it?

Yes. Ask the agent to move an object, change how objects sit, or set the camera position, angle, and move. Preview that move before you generate.

Do I need to know 3D modeling?

No. Ask GPT, Claude, or another agent in plain language. The plugin builds the scene. You can still tell the agent to adjust objects and the camera when you want a precise shot.

How much does one scene cost?

Building one 3D scene costs $0.10. That price is for the scene the agent builds, so you can try more setups before you spend on video generation.

Use it in GPT, Claude, and other agents. Ask for a scene or pass a reference. The agent builds an editable 3D stage for $0.10, then sets the camera and generates.

User cases

Plugin cases

Watch an agent turn a prompt or a reference into a stage, then set the camera before the shot is generated.

In the agent

Ask GPT or Claude to Build the Scene

Stay in the chat. Hand the agent a reference image, and the 3D Builder plugin builds an editable stage instead of leaving you in an empty viewport.

One message · one generated stage

Same chat

Ask the Agent for the Camera Move

In GPT, Claude, or another agent, describe a push, pan, or orbit. The plugin adds that camera move on the scene you already built.

One follow-up · one camera move

Follow-up prompts

Keep One Scene Across the Chat

Ask for a wide shot, then a closer one. The plugin keeps the same stage, so the agent does not rebuild the world in every message.

Same stage · several asks

Still editable

Tell the Agent What to Move

The scene stays editable after the agent builds it. Ask it to move objects and change how they sit before you generate.

Locked layout · fewer wasted generations

GPT, Claude, and more

Direct the Shot from the Agent You Already Use

The plugin runs inside GPT, Claude, and other agents. You ask for the blocking there. Building one scene costs $0.10.

Start in the chat

Ask GPT, Claude, or another agent for the scene. You do not open a separate 3D app to begin.

Rehearse before you generate

Have the agent set the camera position, angle, and move, then look at the frame before the shot is generated.

Generate from that plan

When the stage holds, ask the agent to generate. The shot starts from the scene you directed in chat.

Why the plugin

Plugin in an Agent vs. a Plain Video Prompt

Use the 3D Builder plugin when GPT, Claude, or another agent should build the stage first. A plain video prompt skips that plan.

Focus	3D Builder Plugin	A plain video prompt
Where you work	Inside GPT, Claude, or another agent	One prompt, with no scene to come back to
What you control	Scene, objects, camera position, and camera animation	Whatever the video model infers from the sentence
Best for	A $0.10 scene the agent can keep editing	A single take with no stage to reuse
Typical ask	Build this scene, then move the camera	Make a video that looks like this

See the Scene the Agent Builds

Watch a stage get built, a camera move get set, and a shot get generated. That is the 3D Builder the plugin calls from GPT, Claude, and other agents.

How to use it

From a Chat to a Directed Shot

Add the plugin, ask GPT, Claude, or another agent for the scene, then direct the camera in the same chat.

01
Add the Plugin
Install 3D Builder in Codex, or from the GitHub source, so your agent can call it.
02
Ask for the Scene
In GPT, Claude, or another agent, describe the scene or pass a reference. The plugin builds an editable 3D stage. One scene costs $0.10.
03
Ask for the Shot
Tell the agent to move objects and set a push, pan, orbit, or follow. Then ask it to generate from that stage.

Use 3D Builder in Your Agent

Install the plugin, then ask GPT, Claude, or another agent to build the stage, set the camera, and generate.
