Roblox Scraper Targets 3D Model Sites, Including Adult Content

A crawler linked to Roblox's AI research downloaded over 145 GB of assets while ignoring terms of service and non-commercial licenses.
A crawler identifying as belonging to Roblox downloaded 145.5 GB of 3D models from the sites Open3DLab, SFMLab, and SmutBase, as Open3DLab first reported.
Between October 15 and 16, 2026, the crawler—which used the user agent "trellis2-data-sourcing/1.0"—accessed nearly every project in the sites' catalogs. The scraper downloaded 1,027 files from 712 projects. Open3DLab reports that the crawler ignored the sites' robots.txt, disregarded Terms of Service that forbid scraping, and defied creator licenses, as 423 of the retrieved projects were licensed for non-commercial use only.
Notably, the scraping included adult content. Open3DLab states that 345 of the 712 projects (62.6 GB) were adult content, including 364 files from SmutBase. Examples of retrieved models included characters from *Overwatch* and *Stellar Blade*, as well as a horse cock dildo.
Open3DLab suggests the data was likely intended for training or evaluation of Roblox's 3D foundation model work. The company has been developing a generative AI system called Cube since March 2025. The email address found in the crawler's user agent belongs to a researcher listed as one of the authors of the paper accompanying the Cube system.
Open3DLab blocked the crawler on October 18, though the scraper continued to attempt access through October 20. Roblox has not responded to multiple emails requesting comment on the incident.
