Roblox Unveils Open-Source Cube 3D AI for Text-Driven 3D Object Creation
March 17, 2025
One of Cube's initial tools, mesh generation, enables creators to produce 3D representations from simple prompts, such as generating an 'orange racing car with black stripes'.
The beta launch of the Mesh Generation API is expected to significantly enhance efficiency, allowing developers to quickly generate 3D assets by inputting simple prompts.
Uniquely trained on native 3D data, Cube 3D understands shapes as tokens and can predict subsequent shapes in a sequence for complete object construction.
The central innovation of Cube 3D is its ability to generate 3D objects and environments from text inputs, with future plans to incorporate image input capabilities.
Future updates for Cube 3D will include capabilities for complex object and scene generation, enabling the creation of full environments based on user prompts.
Cube 3D is expected to facilitate the creation of more complex and diverse user-generated content within the Roblox platform, making it a valuable asset for developers.
Roblox has integrated AI tools into its development platform over the past year, including an AI Assistant to streamline the 3D creation process.
Roblox has officially launched and open-sourced Cube 3D, a foundational AI model designed for generating 3D objects, at the Game Developers Conference on March 18, 2025.
This new model allows creators to generate 3D objects using generative AI, marking a significant advancement in the company's capabilities.
Roblox plans to introduce additional AI tools, including text generation, text-to-speech, and speech-to-text features, aimed at enhancing interactive non-player characters and user experiences.
The open-source version of Cube 3D will be available to creators later this week, expanding possibilities for customization and personalized asset creation.
Despite the excitement surrounding AI in gaming, concerns persist, with reports indicating that a significant percentage of developers believe generative AI could negatively impact the industry.
