Scrape-detection tool for 3D asset creators

What to build

A provenance-check web tool for 3D/game asset creators (starting with Roblox) to search whether their models were scraped into AI training datasets, plus one-click DMCA/opt-out request generation — a 3D-asset version of Have I Been Trained.

Roblox allegedly scraped 145GB of creator-made 3D models, including adult content, without consent — echoing the 2D art-training backlash that spawned tools like Have I Been Trained, but no equivalent exists yet for 3D/game assets.

Demand

3D modelers, Roblox UGC creators, and game-dev asset sellers who feel exploited by platform AI training want a way to check exposure and file takedowns, especially after this report went viral.

• Hacker NewsEngagement

  Roblox downloaded 145GB of models from our sites (including adult content) without asking — 460 points, 268 comments on HN, high engagement at the source.

• Analyst opportunity noteAnalysis

  Notes existing precedent of 2D artists paying for or adopting Have I Been Trained and Spawning.ai opt-out tooling, with no equivalent yet for 3D/game assets.

Stack

• Next.js
• Postgres + pgvector
• Open3DLab/public dataset scraping APIs
• 3D geometry hashing (e.g. point-cloud fingerprinting)
• Stripe
• Resend for takedown email generation

Solo + AI difficulty

Hard part is 3D similarity matching (geometry/texture/rigging variance) vs. easy 2D image hashing; MVP could start with filename/metadata matching against known scraped dataset dumps before tackling real geometric fingerprinting. Rough time-to-MVP: 3-4 weeks for a basic searchable index and takedown template generator.

Entry threshold

No licences needed and the product itself is just a web scanner plus template generator, but matching assets against leaked or scraped datasets requires getting hold of or indexing those datasets, which adds real engineering effort beyond a plain CRUD app.

Where to find first users

• r/robloxgamedev
• Open3DLab community (source of the leak)
• DeviantArt/ArtStation 3D creator forums
• Product Hunt launch

Competitors

• Have I Been Trained
• Spawning.ai

Counter-signals & risks

• Roblox's terms of service may already grant it broad rights to use uploaded models, making the 'without asking' framing legally contentious rather than clearly unauthorized.

• 3D asset provenance detection is technically harder than 2D image matching due to geometry, texture, and rigging variation, undermining a direct port of the Have I Been Trained approach.

• The market for 3D/game-dev creator opt-out tools may be far smaller than the 2D art market, limiting commercial viability.
