Roblox has launched the open beta for its new 4D creation feature, marking a major leap forward in how users design and interact with digital content on the platform. Building on last year’s introduction of Cube 3D—an open-source AI model that generates 3D objects like furniture, vehicles, and accessories—Roblox is now enabling creators to build fully functional, interactive objects. Since Cube 3D’s debut in March, users have generated over 1.8 million 3D objects. The new 4D feature takes this a step further by adding motion and responsiveness, transforming static models into dynamic, playable items within games. This innovation allows creators to design objects that move and react to player actions, enhancing realism and immersion. The open beta, available after a period of early access since November, introduces two initial object templates, or “schemas.” The first is “Car-5,” which enables users to generate cars composed of five distinct parts: a body and four wheels. Unlike previous versions, where cars were fixed, solid objects, the 4D system allows each component to be animated—wheels spin, doors open, and parts move independently, creating a more lifelike experience. The second template, “Body-1,” is designed for single-piece objects such as boxes or sculptures, offering a simpler entry point for basic interactive designs. The first experience built using 4D creation is a game called Wish Master, where players can generate and drive custom cars, pilot planes, and even ride dragons—all created in real time using AI. This showcases the feature’s potential to empower users to rapidly prototype and play with complex, interactive elements. Looking ahead, Roblox plans to give creators the ability to design their own custom schemas, allowing for greater control over how objects behave and interact. The company is also developing advanced tools that use reference images to generate 3D models that match the image’s style and details, expanding the creative possibilities for artists and developers. Additionally, Roblox is working on a project called “real-time dreaming,” which CEO David Baszucki described as a way for creators to build entire game worlds using keyboard navigation and real-time text prompts. This could dramatically lower the barrier to entry for game development by enabling rapid, AI-assisted world-building. The launch of the 4D creation feature comes amid broader efforts to enhance safety and trust on the platform. Just recently, Roblox implemented mandatory facial verification for users accessing chat features, a move driven by ongoing legal scrutiny and investigations into child safety concerns. The integration of AI-powered creation tools now sits alongside these safety upgrades, reflecting Roblox’s dual focus on innovation and user protection.
