Roblox has opened a new tool for creators that makes game objects behave like real things. The feature is called 4D creation, and it is available in open beta now. The system uses the Cube foundation model to turn simple prompts into parts that move and interact inside Roblox worlds.

What is 4D
Roblox 4D splits objects into parts and gives each part a behavior. The platform ships two starter templates named Car 5 and Body 1. Car 5 builds a five-part car with a body and four wheels. Body 1 makes single-piece objects like a box or sculpture. These schemas let the model add motion and logic so cars can roll and wings can move.
How it Works
The Cube model learns shapes and actions from many examples. When a creator asks for a car, the model returns a set of parts and a script that links those parts together. The result is an object that behaves correctly in gameplay. Roblox used a demo game called Wish Master to show cars that drive planes that fly and dragons that move. Creators can use the beta to test these behaviors in real play.
Roblox plans to let creators design their own schemas later. The company is also working on ways to turn a reference image into a detailed 3D model that matches the picture style. That will let artists move from a flat sketch to a working game asset in fewer steps. Roblox calls the project a step toward 3D intelligence, and it aims to make asset creation faster for a wide set of creators.
Breaking Down Complexity
Breaking objects into parts and behaviors changes how games get built. Small teams can make more complex toys and props without hand-building every joint and script. The approach also opens design space. Creators will be able to iterate faster and try ideas that once took many hours to code and test.

Roblox tied this beta to broader platform changes that include safety updates. The company has said that it will keep safety controls in place while rolling out new AI tools. Part of that work includes the platform changes that gate certain chat and social features behind identity checks to protect younger users.
How to Try
Creators can access the open beta through Roblox Studio and the Cube model resources on the project pages. The official Cube code and examples are available to download for experimentation and research. The public tools let creators try the two starter schemas and share results with the Roblox community.
