Roblox's 4D Creation Feature Now in Open Beta

Last year, Roblox introduced an open-source AI model that can generate 3D objects on its platform, helping users quickly design digital items such as furniture, vehicles, and accessories. The company claims that this tool, named Cube 3D, has assisted users in creating over 1.8 million 3D objects since its launch in March of last year.

On Wednesday, the company rolled out the highly anticipated open beta for its 4D creation feature. This functionality allows creators to build not only static 3D models but also fully functional and interactive objects. The feature had been in an early access phase since last November.

Roblox stated that 4D creation introduces a crucial new layer: interactivity. With this technology, users can design items capable of moving within games and responding to players.

At launch, two types of object templates, referred to as "modes," are available for creators to experiment with.

The first is the "Car-5" mode, designed for creating vehicles composed of five separate parts: the main body and four wheels. Previously, a car was a single, solid 3D object incapable of movement. The new system breaks objects into components and assigns behaviors to each part, enabling them to function independently within the virtual world. Consequently, the AI can generate cars with rotating wheels, making them more realistic and interactive.

The second mode is called "Body-1," which can generate any object consisting of a single part, such as a simple box or a sculpture.

The first experience featuring 4D generation is a game named Wish Master, where players can generate cars they can drive, planes they can fly, and even dragons.

Looking ahead, Roblox plans to enable creators to build their own modes, granting them greater freedom to define object behaviors. The company also mentioned it is developing new technology to create detailed 3D models that match the style of reference images (as shown in the example below).

The company noted it is working on additional methods to assist people in using AI to create games and experiences, including a project known as "Real-Time Dream." Last month, Roblox CEO David Baszucki explained that this project would allow creators to build new worlds using "keyboard navigation and shared real-time text prompts."

The open beta follows closely after Roblox's recent implementation of mandatory facial verification, where users must pass facial verification to access in-game chat features. This move is in response to lawsuits and investigations related to child safety.
