Roblox has announced Cube 3D, a new open-source AI system for generating 3D objects and scenes from text prompts — alongside a slew of other tools and updates for AI-assisted game development.
3D generation AI
The details:
- Cube 3D generates complete, functional 3D objects from text prompts, training on native 3D data instead of traditional image-based reconstruction.
- Developers can generate assets through simple commands like "/generate motorcycle," with image input capabilities also coming in the future.
- Cube uses ‘3D tokenization’ to predict and generate shapes the same way language models predict text, enabling future 4D scene generation capabilities.
- Roblox also released updates to its Studio content creation suite including improved performance, real-time collaboration features, and monetization tools.
Why it matters: Between ‘vibe-coding’, Gemini’s new native multimodal image capabilities, and open-source tools like Cube 3D, it has never been easier to take a game from idea to reality. With 85M+ daily active users, these AI tools will supercharge both Roblox’s growth and the ability for users to build and monetize on the platform.
