Roblox Rolls Out CubePart AI to Build 2 Million-Part Functional Game Objects

Summary
Starting today, Roblox is adding CubePart AI to Roblox Studio and supported games, letting developers and players generate in-game objects with working parts such as vehicles, weapons and robots.
CubePart extends Roblox's 3D object generation from last year by producing multipart assets that fit game physics; Roblox says it trained the model on 2 million parts across 500,000 assets.
Developer opt-in and existing moderation rules will limit where the tool appears, while technical constraints still cap object complexity and keep the system better suited to machines than lifelike creatures.
Roblox frames the release as a step toward AI-built worlds, with Roblox Reality targeting 2K at 60 fps later this year or in early 2027 and multiplayer world generation still not stable enough.
Can Roblox's AI solve the multiplayer challenge to deliver the first truly collaborative, AI-generated worlds?
Will Roblox's new AI tools truly empower creators, or will platform fees create insurmountable barriers for them?
CubePart AI’s 2026 Rollout: How Roblox’s Generative 3D Mesh Tool is Democratizing Game Creation and Shaping the Industry
Overview
Roblox's generative AI journey, first noted in 2023, has become reality with the June 2026 launch of CubePart AI. This breakthrough tool is directly integrated into Roblox Studio, making 3D asset creation faster and easier for both new and experienced creators. Using advanced open-vocabulary and part-controllable generation, CubePart AI lets users describe assets with natural language and customize individual parts. This innovation empowers more people to create on Roblox, lowers the learning curve, and speeds up development, marking a major step in making 3D content creation accessible and efficient for everyone on the platform.
