Roblox has launched Cube, an open-source AI model designed to simplify 3D object creation through text-based prompts.
Highlights
This tool enables developers—both within and outside the Roblox platform—to generate detailed 3D assets with minimal effort.
Cube aligns with Roblox’s broader push toward AI-driven content creation, offering new ways for creators to build immersive virtual worlds.
Cube’s Functionality and Beta Release
Initially announced at Roblox’s annual developer conference, Cube is now being showcased at the Game Developers Conference (GDC).
Its first major feature, 3D mesh generation, is currently in beta and will be accessible to Roblox creators later this week.
This feature allows users to create meshes (3D representations of objects) simply by describing them in natural language. For example, a prompt like “generate an orange racing car with black stripes” will produce a fully formed 3D model, which can then be refined within Roblox Studio.
Cube functions by tokenizing 3D shapes, predicting, and constructing objects based on these tokens—similar to how text-based AI models generate sentences.
It has been trained using a mix of licensed datasets, publicly available 3D assets, and contributions from the Roblox ecosystem.
Expanding Beyond Roblox: Open-Source Potential
By making Cube open-source, Company extends its potential beyond its own platform. External developers can modify the model, create custom plugins, or train it with their own datasets, adapting it for various applications.
This positions Roblox alongside other AI-driven gaming innovations, such as Tencent’s recently launched open-source AI model for 3D generation.
Beyond Cube, Roblox is working on additional AI-powered tools to enhance game development. Upcoming features include:
- Text-to-speech and speech-to-text capabilities to improve accessibility and player interaction.
- AI-powered NPCs that respond to player dialogue in a more realistic way.
- Voice command integration for gameplay interactions and in-game narration.
Future Enhancements: Towards 4D Creation
They plans to expand Cube’s capabilities further. Future updates may introduce:
- Multimodal inputs, allowing users to generate 3D objects using images or videos.
- Scene generation, where entire environments can be created from a single prompt (e.g., a forest scene that can be adjusted for different seasons).
- “4D creation,” where AI-generated objects and environments interact dynamically with players and other game elements.
Industry Impact and AI Concerns
The integration of AI in game development continues to spark discussion. A recent GDC report found that 30% of game developers believe generative AI could have negative effects on the industry, citing concerns about automation and job security.
A study by CVL Economics suggests that AI advancements could impact or replace 13.4% of gaming jobs by 2026.
Despite these concerns, Roblox sees AI as a tool to empower independent developers and accelerate content creation.
The company has already introduced AI-driven tools for texture generation and avatar creation, and Cube aims to make 3D modeling more accessible for developers of all skill levels.
As AI integration in gaming advances, Cube’s open-source model could encourage broader adoption and innovation, shaping the future of AI-assisted content creation.
