Roblox releases its open-source model that can create 3D objects using AI | TechCrunch

Mar 17, 2025 - techcrunch.com
Roblox has launched "Cube," a 3D model that allows creators to generate 3D objects using generative AI, with an open-source version available for external developers. Initially announced at Roblox's developer conference, Cube is being demoed at the Game Developers Conference (GDC) and will be accessible to creators later this week, starting with a mesh generation tool. This tool enables the creation of 3D object representations from simple prompts, which can be further customized in Roblox Studio. The open-source version allows for customization, plug-in creation, and model training with personal datasets. Roblox also plans to introduce additional AI tools, including text generation, text-to-speech, and speech-to-text, in the coming months.

Roblox's future plans include expanding mesh generation to more complex objects and developing a scene generation tool for creating dynamic environments. The company aims for "4D creation," where objects, environments, and people interact. While AI tools like Cube are expected to accelerate development and empower indie creators, concerns persist about AI's impact on the gaming industry. A GDC report indicates that 30% of developers feel generative AI negatively affects gaming, and a CVL Economics study projects that 13.4% of gaming jobs could be impacted by AI by 2026.

Key takeaways:

  • Roblox launched a 3D model called "Cube" for creators to generate 3D objects using generative AI, with an open-source version available for external customization.
  • Cube's first tool, mesh generation, allows creators to generate 3D representations of objects using a single prompt and is currently in beta.
  • Roblox announced additional AI tools for text generation, text-to-speech, and speech-to-text, with plans for more complex mesh and scene generation in the future.
  • While AI tools in gaming are advancing, there are concerns about their impact on the industry, with studies projecting potential job impacts by 2026.
