Roblox has launched an open beta for its new 4D creation feature, allowing users to create interactive objects instead of just static 3D models. This feature builds on last year's release of Cube 3D, an open-source AI model that has already generated over 1.8 million 3D objects on the platform. The 4D technology introduces interactivity, enabling items to move and respond to players, significantly enhancing the user experience. At launch, there are two schemas available for creators. The "Car-5" schema allows users to construct a car from five separate parts, enabling realistic movement, like spinning wheels. The "Body-1" schema generates objects made from a single piece, such as boxes or sculptures. A game called Wish Master showcases this new capability, where players can create and control vehicles and even mythical creatures like dragons. Roblox plans to expand its 4D creation tools by allowing creators to design their own schemas, giving them more flexibility. The company is also working on technology to generate detailed 3D models from reference images. CEO David Baszucki mentioned a project named “real-time dreaming,” which aims to let creators build worlds using text prompts and keyboard navigation. Meanwhile, the platform has implemented mandatory facial verification for users accessing chat features, a response to recent concerns about child safety.
