Roblox opens beta for 4D AI objects that generate interactive, drivable assets

Roblox is widening access to a new generation workflow that turns prompts into usable game assets, not just static meshes—an important shift for studios and brands building interactive experiences on the platform.

4D creation brings AI-generated assets into gameplay

In an open beta launched Wednesday, Roblox introduced “4D creation,” a feature that uses AI to generate functional objects that can move and respond to players. Unlike typical 3D generation, Roblox’s approach adds interactivity as a first-class layer: objects are built from components and assigned behaviors so they work inside an experience.

Roblox positions this as the next step after its open-source Cube 3D model, which the company says has already been used to generate more than 1.8 million 3D objects since March last year. The new 4D system has been in early access since November and is now available more broadly via open beta.

Schemas, part-based objects, and what creators can do now

At launch, creators can experiment with two schemas (templates). “Car-5” generates a vehicle composed of five parts—the chassis plus four wheels—so wheels can spin and the car can behave like a drivable object, rather than a single rigid model. The second schema, “Body-1,” supports single-piece items such as boxes or sculptures.

Roblox is also showcasing a first implementation inside the experience Wish Master, where players can generate vehicles like cars and planes and then use them in-game.

Looking ahead, Roblox says it plans to let creators author their own schemas, which would effectively let teams define reusable “behavior blueprints” for generated assets. The company is also developing image-to-3D capabilities to match a reference style, plus a project CEO David Baszucki has described as “real-time dreaming,” using keyboard navigation and real-time text prompts to build worlds on the fly, per his public comments on YouTube.

For B2B marketers and commerce-led game teams, the key implication is speed: faster iteration from concept to interactive asset, with increasing control via schemas as Roblox expands the system.
