Roblox Corporation has revealed a new generative AI system designed to create interactive game environments in real time, but its first public showcase has already raised questions about originality. The demonstration, meant to highlight how players can use AI to “paint” playable worlds, appeared to closely resemble environments and characters from Clair Obscur: Expedition 33, Sandfall Interactive’s 2025 Game of the Year.
The tool, which Roblox calls a “real-time, action conditioned world model,” allows creators to combine text, image, and video prompts to generate environments that can immediately be explored and shared with others on the Roblox platform. Roblox says users will be able to walk through a space, issue prompts, and convert those ideas into 3D worlds that multiple players can enter at once.
While the feature is positioned as a way to speed up development and lower the barrier to entry for creators, the example used to show off the technology quickly became the center of discussion.
How Roblox’s AI “Painting” System Works
According to Roblox, the system operates alongside Roblox Studio and its internal Cube Foundation Model. The idea is that instead of building every asset by hand, creators can prompt the AI to generate terrain, lighting, and objects in real time. Roblox describes this process as letting users “paint” a world and then convert it into a playable environment inside the platform’s ecosystem.
The company also announced a related feature called “4D generation,” which focuses on producing functional objects rather than static meshes. These AI-generated items can include behaviors and physics, allowing them to be imported directly into Roblox experiences. Roblox frames this as a step toward letting both players and developers generate interactive content rather than only visual assets.
This approach fits into Roblox’s broader push to expand its creator economy, where millions of users build, share, and monetize experiences. It also aligns with trends across gaming and web3-adjacent platforms that aim to automate parts of development through generative AI.
Similarities to Clair Obscur: Expedition 33
The controversy started when Roblox shared a short clip generated from a prompt describing a “woman in a glowing cave.” Viewers quickly noticed that the resulting scene looked strikingly similar to Clair Obscur: Expedition 33. The environment resembled the Flying Waters location from the game, and the character model appeared close to Maelle’s design, including her outfit and overall silhouette.
Players pointed out that the scene did not just evoke a general fantasy style but appeared to replicate specific visual elements from Sandfall Interactive’s work. Replies to Roblox’s post questioned what data the AI model had been trained on and whether copyrighted material was involved in the process.
Roblox later stated that the system was trained on “a combination of data, including proprietary Roblox 3D avatar/world interaction data.” The wording left room for interpretation, and it did not fully address concerns about how closely the AI output matched an existing commercial game.
At the time of writing, Sandfall Interactive has not released an official response to the demonstration.
Training Data and Copyright Questions
The situation reflects a broader issue facing generative AI across the games industry. While companies present AI tools as productivity aids, developers and players continue to question how training data is sourced and how much influence copyrighted works have on generated results.
If an AI system produces environments and characters that are clearly recognizable as another studio’s property, the line between inspiration and replication becomes harder to define. Roblox’s showcase has already been compared to Google’s Project Genie, which recently demonstrated AI-generated worlds that resembled Nintendo franchises such as Mario and Zelda.
In those cases, too, questions surfaced about whether AI tools could undermine creative ownership. For platforms built on user-generated content and monetization, the risks are not only legal but also reputational, especially if creators unknowingly publish AI-made assets that resemble protected IP.
What This Means for Roblox Creators
Roblox has long promoted itself as a space where players can become developers, and generative AI fits into that strategy by reducing technical complexity. The ability to generate worlds through prompts could make experimentation faster and more accessible.
At the same time, the Clair Obscur comparison highlights a potential downside. If AI tools produce content that is too close to existing games, creators could face takedowns, disputes, or restrictions when publishing their projects. It also places responsibility on Roblox to clarify how its models are trained and how originality is protected within the platform.
For web3-influenced creator economies that emphasize ownership and attribution, these questions are especially important. Automation can help scale creativity, but it also raises expectations around transparency and respect for existing work.
An Industry Still Defining Its Boundaries
Roblox’s AI world builder is part of a growing wave of real-time generative tools in gaming. Studios and platforms are experimenting with systems that can transform prompts and footage into playable spaces, but the industry is still defining where acceptable use ends and copying begins.
The Clair Obscur example shows how quickly these tools can run into scrutiny once recognizable material appears in a public demo. Until Roblox and other companies offer clearer explanations about training data and safeguards, similar controversies are likely to continue as generative AI becomes more common in game development.

Frequently Asked Questions (FAQs)
What is Roblox’s real-time world model?
It is a generative AI tool that lets creators use text, image, and video prompts to generate playable 3D environments inside Roblox in real time.
Why are people comparing it to Clair Obscur: Expedition 33?
Roblox’s demo showed a scene with a glowing cave and character that closely resembled locations and designs from Clair Obscur: Expedition 33, including the Flying Waters area and Maelle’s outfit.
Did Roblox copy Clair Obscur directly?
Roblox has not said it copied the game. It stated the model was trained on a mix of data including proprietary Roblox data, but it has not detailed whether external copyrighted material influenced the output.
What is 4D generation in Roblox?
4D generation is a feature of Roblox’s Cube Foundation Model that allows creators to generate functional objects with behavior and physics, not just static visuals, for use in Roblox experiences.
How does this affect Roblox creators?
AI tools can speed up development, but if generated assets resemble copyrighted games, creators may risk disputes or content removal. Transparency around training data and originality becomes important.
Is this part of web3 gaming trends?
While Roblox is not fully web3, its creator economy and AI automation overlap with web3-style ideas around ownership and user-generated content, making issues of attribution and rights more relevant.
