According to Open3DLabTrackers associated with online gaming platforms Roblox took 145.5 GB of 3D models from Open3DLab and its sister sites (SFMLab and SmutBase).. He was also accused of ignoring website restrictions. The material contains adult content. Open3DLab administrators suspect that this is artificial intelligence training or test data, although they cannot prove it.
Subsequently, Roblox admitted that a researcher on its team had developed a public 3D resource harvesting agent. This agent accidentally extracted some components from Open3DLab. According to a company spokesperson, they took the agent out of service and the data was not used for anything, nor was it used to train AI models.
Download and page restrictions
Original Complaint: October 26, 2026. Download days: 15 and 16. The program visited 18,926 project pages (with 26,429 requests in 34 hours). He then downloaded full copies of 1,027 files (from 712 projects).
The tracker called himself trellis2-data-sourcing/1.0 And used an email with the roblox.com domain All requests originate from the same Amazon Web Services IP. According to Open3DLab, this email belongs to a researcher who signed the Cube (Roblox’s generative AI system) work.
On the other hand, the program inspects the robots.txt file (where crawlers are instructed). however, Bypass the limitation and Terms of Use Indicates that automatic extraction cannot be performed. Also, projects that had a restricted (non-commercial) license were downloaded.
364 files (from 224 projects) downloaded from SmutBase (which only contains adult content). Its size is 54.8 GB. Adding the projects identified as mature from SFMLab, we have a total of 345 projects (62.6 GB).
Once all this was done, the people responsible for Open3DLab sent two emails requesting an explanation.
Likewise, it should be noted that training is also questionable because of the way Roblox works with cubes. The system was introduced in March 2025. This is one Generative AI models which allows you to create three-dimensional objects from textual instructions. Roblox plans to expand its ability scenes and characters. In February 2026 they launched the 4D generation beta (to create interactive objects).
It should also be noted that Open3DLab does not believe that adult content was intended to be searched. However, as it appears in their records, they did not distinguish between such materials and the rest.
