Open3DLab accuses Roblox of downloading 145GB of 3D assets for AI training purposes

Independent 3D modeling community Open3DLab has publicly warned that a web crawler, linked to the gaming platform Roblox, mapped "almost every project" on its website, along with sister sites SFMLab and SmutBase, downloading 145.5GB of data in the process. In a blog post, Open3DLab reports that "complete copies" of 1,027 files from 712 projects were sourced in the process, which it believes were taken for "AI training purposes."

  • The data center cooling state of play
  • The custom AI ASIC state of play
  • America’s AI chip rules keep changing — and the rest of the world is paying the price
  • GTC 2026: Ian Buck press Q&A transcript — VP of Hyperscale and HPC speaks out on shelving CPX and shipping LPU decode this year
  • Demand for data center CPUs has surged, and AI agents are responsible

The crawler read "practically [its] entire catalogue" of 18,926 projects in a span of 34 hours over a total of 26,429 requests. Once it was done, the crawler downloaded 1,027 files from 712 projects before it "suspended operations." Files downloaded include 364 files, or 54.8GB worth, from 224 projects hosted on SmutBase, OpenLab's sister site focused on adult content. A further 345 projects of adult-marked SFMLab projects, or 62.6GB worth, were also taken.

According to Open3DLab, the crawler's "main limiting factor" was its use of free download servers that capped speed and concurrent downloads. The scraping was detected on the same day, and blocked by the following morning.
