Roblox has launched Cube 3D, an open-source AI model for generating 3D objects using text prompts, expanding the creative possibilities of developers and driving innovation in the industry.

Key Points:

  • Cube 3D Launch: Open-source AI model for creating 3D objects using text prompts.
  • Mesh Generation: First feature available to rapidly develop 3D objects in Roblox Studio.
  • Multimodal Future: Cube 3D will evolve to integrate input from images, text, and video.
  • Creative Expansion: Developers will be able to customize and train Cube 3D on their own data.


Roblox recently announced Cube 3D, an open-source AI model designed to generate 3D objects. The tool aims to make 3D content creation more efficient, allowing developers to quickly explore new creative directions and increase productivity. Cube 3D is based on a technique that tokenizes 3D shapes to predict and build complete objects. The model was trained using a combination of licensed, publicly available datasets and data from the Roblox ecosystem. In the future, Cube 3D will become multi-modal, allowing 3D object generation from various inputs such as images, text and videos, integrating with Roblox’s existing AI tools.

In parallel, Tencent launched Hunyuan3D 2.0, an advanced open-source system for synthesizing high-resolution 3D assets. The system consists of two main components: Hunyuan3D-DiT, a model for large-scale shape generation, and Hunyuan3D-Paint, a model for large-scale texture synthesis. Hunyuan3D 2.0 can transform text descriptions into detailed 3D models in minutes, revolutionizing industries such as gaming, animation and e-commerce. The speed and efficiency of this system represent a significant leap forward in 3D content creation.

These developments highlight a growing trend towards open source in the field of AI for 3D content generation, offering powerful tools to both experienced and novice developers, and fostering innovation through collaboration and knowledge sharing.
