Last year, Roblox introduced an open-source artificial intelligence model designed to generate 3D objects directly on its platform. This innovation empowered users to rapidly craft digital assets such as furniture, vehicles, and accessories. The company reports that this tool, named Cube 3D, has facilitated the creation of over 1.8 million 3D objects since its rollout in March of the previous year.
This Tuesday, the company advanced its creative toolkit by launching the open beta for its highly anticipated 4D creation feature. This functionality allows creators to move beyond static 3D models, enabling the development of fully functional and interactive objects. The feature had been accessible in an early access phase since November.
Roblox highlights that 4D creation introduces a critical new dimension: interactivity. Leveraging this technology, users can now engineer items that exhibit movement and dynamically respond to players within the game environment.
At its debut, creators can experiment with two distinct types of object templates, officially referred to as schemas.
The first is the “Car-5” schema, specifically designed for constructing vehicles from five separate components: the main body and four wheels. Previously, cars existed as single, rigid 3D objects incapable of motion. This new system meticulously breaks down objects into individual parts, assigning specific behaviors to each, thereby allowing them to function independently within the virtual world. Consequently, the AI can generate cars with spinning wheels, significantly enhancing their realism and interactive capabilities.
The second template, known as “Body-1,” is optimized for generating any object composed of a single piece, ranging from a simple box to an intricate sculpture.
The inaugural experience showcasing 4D generation is a game titled "Wish Master," where players are granted the ability to create and interact with driveable cars, flyable planes, and even fantastical dragons.
In its future roadmap, Roblox plans to empower creators to design their own schemas, offering them greater flexibility in defining how objects behave. The company also disclosed its development of new technology that could leverage a reference image to produce a detailed 3D model, faithfully matching the aesthetic style of the input image.
The company further stated its commitment to developing additional AI-driven methods to assist in the creation of games and experiences, including a project it has dubbed “real-time dreaming.” Roblox CEO David Baszucki elaborated last month that this ambitious project would enable creators to construct new worlds through "keyboard navigation and sharing real-time text prompts."
This launch of the open beta closely follows Roblox's recent implementation of mandatory facial verification for users seeking to access in-game chat features, a measure introduced in response to ongoing lawsuits and investigations concerning child safety.
