Roblox 3D Scrape - What Creators Should Lock This Week - 2026
If you searched roblox scrape after October 26–28, 2026, you do not need another rewrite of the Open3DLab headline. You need a this-week lock list.
On October 26, Open3DLab published that a crawler presenting itself as belonging to Roblox walked Open3DLab, SFMLab, and SmutBase on October 15–16, downloading complete copies of 1,027 files from 712 projects — about 145.5 GB, including adult-tagged packs. Open3DLab says the crawler retrieved robots.txt, then ignored it, ignored Terms that forbid scraping, and ignored creator licenses. On October 28, GameDeveloper reported Roblox’s statement: the agent failed to operate as intended, was decommissioned, and the gathered data was not used for any purpose, including training any AI models, with process strengthening underway.
Primary report: Roblox downloaded 145 GB of models from our sites (including adult content) without asking. That page owns the incident narrative. This URL owns the creator and host week list — what to take offline, what license line to keep public, and what Roblox’s reply does and does not clear.
This is not the Meshy → Roblox 20 MB Stop (upload size gate). It is not the Roblox Studio guide (editor how-to). It is not a general AI-ethics essay. It is the lock map after a named scrape week and a named company reply.
Why this matters now
Hacker News item 50256985 and Lemmy mirrors moved this from niche host drama into mainstream creator chat within hours. Discord pastes already split into three bad defaults:
- “Roblox said they will not train on it, so leave every pack public forever.”
- “Nuke every free pack tonight and never host again.”
- “If you ship on Roblox Cube, you somehow caused this.”
None of those is a plan.
Direct answer: Treat the Open3DLab report as a real scrape event with dated volume and scope. Treat Roblox’s October 28 statement as a decommission + non-use claim for that gathered set, not a blanket promise that every future crawler, every dataset, or every third-party mirror is safe. This week, lock host exposure, license clarity, and Roblox-side asset provenance — then reassess after you have receipts, not vibes.
Who this lock list is for
| Audience | Use it to… |
|---|---|
| Beginners | Know what happened in plain language before panicking offline |
| Developers | Separate host controls, license text, and Roblox upload provenance |
| Creators | Paste a one-screen “what we lock this week” note into Discord |
| Companies | Diligence — scrape incident ≠ cleared training policy forever |
Time: 35–50 minutes to read and run the week checklist; longer if you inventory a large pack library.
Honest limit: Open3DLab and Roblox (via GameDeveloper) are the authorities for facts. This page does not litigate intent, does not invent Roblox internal docs you cannot see, and does not replace counsel for commercial licensing.

The one-paragraph version
Between October 15 and 16, 2026, Open3DLab says a Roblox-labeled crawler copied 145.5 GB across three related model sites, including adult content, while ignoring robots rules, Terms, and licenses. On October 28, Roblox told GameDeveloper the agent misfired, was decommissioned, and that data was not used for training or other purposes. News pages explain the fight. Creators still need a Monday list: reduce scrape surface, publish a clear license stance, stop mixing unverified external packs into live Roblox experiences, and write down what “cleared” means for your team — because a press statement about one agent is not an infinite indemnity.
Timeline you can quote without embroidery
| Date | What happened | What creators should hear |
|---|---|---|
| Oct 15–16, 2026 | Open3DLab: crawler walked projects and downloaded complete files (~145.5 GB, 1,027 files, 712 projects) | Volume and multi-site scope are the story, not a single ZIP |
| Oct 18, 2026 | Open3DLab noticed heavy request patterns in logs | Hosts detect late; do not assume quiet logs mean safe forever |
| Oct 26, 2026 | Open3DLab public post | Primary source for hosts and journalists |
| Oct 27, 2026 | HN / Lemmy amplification | Community demand spike; lock decisions this week, not “after the discourse cools” |
| Oct 28, 2026 | Roblox statement via GameDeveloper | Decommission + non-use claim for gathered data; process strengthening claimed |
Keep the table short when you paste. Do not invent “Roblox admitted training on adult packs” — that is not what the October 28 statement says. Do not invent “Open3DLab proved a named production model was trained” — Open3DLab itself frames training as an assumption they are investigating, not a courtroom verdict you should restate as fact.
What Roblox’s statement clears — and what it does not
Cleared (for diligence language this week)
- Roblox publicly addresses the Open3DLab allegations through a spokesperson quote.
- The company claims the agent was decommissioned.
- The company claims the gathered data was not used for any purpose, including AI training.
- The company claims it is strengthening related processes.
Not cleared (do not pretend these are solved)
| Claim people want | Status after Oct 28 |
|---|---|
| “No Roblox crawler will ever hit open model hosts again” | Not promised |
| “Every third-party mirror of those files is gone” | Not promised |
| “Creator licenses were respected during the crawl” | Open3DLab says the opposite for the event |
| “Adult content was never downloaded” | Open3DLab says it was; Roblox frames misfire + non-use |
| “Your private Discord pack drop was scanned” | Unknown — different threat model |
| “Shipping on Roblox implies consent to train on your UGC forever” | Separate policy surface; not this incident’s receipt |
Company note: For partner or investor Q&A, quote the GameDeveloper piece and the Open3DLab post by URL and date. Do not paraphrase into “Roblox apologized for training on NSFW.” That paraphrase fails diligence.
Beginner path — first 45 minutes
Prerequisites: access to wherever you host packs (Open3DLab-style sites, personal CDN, Gumroad, Drive) and, if you publish on Roblox, Studio access to your live experience.
- Read the two primaries — Open3DLab post + GameDeveloper confirmation. Ten minutes. No Twitter threads first.
- Inventory public packs — list every URL that serves downloadable meshes/textures you care about. Spreadsheet with columns: URL, license, adult-tagged Y/N, last updated, keep public Y/N.
- Mark high-risk rows — adult-tagged, “do not redistribute,” exclusive buyer packs mirrored free, or packs with no license line at all.
- Apply one host action per high-risk row — unpublish, gate behind login, replace with watermarked preview-only, or leave public with an explicit AI/training refusal line if that matches your lawyered stance.
- Roblox side — for each live MeshPart / imported model from an external host, note source URL and purchase receipt if any. Flag anything you cannot provenance.
- Write a three-line team note — what you locked, what you left public, what you are waiting on (counsel, host tools, Roblox follow-up).
Common beginner mistakes: deleting everything without a backup; assuming “CC-BY” already bans training (it depends on jurisdiction and wording — get counsel); assuming Roblox experiences auto-ingest every free pack on the internet.
Host lock list — open model sites and CDNs
If you run or heavily depend on open 3D hosts, this week is about surface area, not vibes.
H1 — Rate limits and bots you actually control
| Lock | Do this week | Pass if… |
|---|---|---|
| H1a | Confirm CDN / app firewall rate limits for anonymous download bursts | Burst caps exist and are documented |
| H1b | Verify robots.txt is served and matches your intent |
File retrieved; disallows match policy |
| H1c | Remember robots is a request, not a lock | You also have auth, tokens, or signed URLs for sensitive packs |
| H1d | Log user-agent + IP aggregates for bulk downloaders | You can spot another Oct 15–16 pattern within a day |
Open3DLab’s report stresses that the crawler retrieved robots rules and still proceeded. Treat robots as signal, not shield.
H2 — Terms and license text that humans can scrape-read
| Lock | Do this week | Pass if… |
|---|---|---|
| H2a | Terms forbid automated bulk download / training use in plain language | Linkable Terms page, dated |
| H2b | Per-pack license line visible next to download | Not buried in a 2019 forum post |
| H2c | Adult packs isolated from “safe for work training corpus” browsing paths | Separate sections or hard gates |
| H2d | DMCA / abuse contact reachable | Mailbox monitored this week |
H3 — What to take offline vs leave public
| Pack type | Default this week | Why |
|---|---|---|
| Adult-tagged full downloads | Gate or remove anonymous full ZIP | Highest controversy surface in the Open3DLab report |
| Exclusive paid packs mirrored free | Offline until rights clear | License conflict risk |
| WIP meshes with no license | Add license or unpublish | Ambiguity invites bad faith use |
| Old packs you no longer want associated with your brand | Archive privately | Reputation, not just bytes |
| Freely licensed demo props you still want discovered | Keep public + clear AI stance line | Discovery still matters |
H4 — Honest host mitigations (and their limits)
- Login walls raise cost; determined actors still try.
- Signed short-TTL URLs beat forever-public object storage links.
- Preview GLBs can stay public while masters stay private.
- Hash lists of known stolen ZIPs help takedowns; they do not rewind a completed crawl.
- Suing is not a same-week lock — do not block the checklist waiting on litigation fantasy.
Creator lock list — people who ship on Roblox
Roblox creators did not cause Open3DLab’s crawl. You still have Monday work if your pipeline mixes external packs into experiences.
R1 — Provenance before polish
| Lock | Do this week | Pass if… |
|---|---|---|
| R1a | Tag every external mesh in a sheet: source, license, purchase ID | No “I found it somewhere” rows on live |
| R1b | Quarantine packs whose license forbids Roblox redistribution | Removed from live or replaced |
| R1c | Separate “lab imports” from “shipped experience” folders | Lab cannot publish by accident |
| R1d | Prefer first-party or Marketplace assets with clear terms for new work this week | New live content has a documented source |
R2 — Do not launder scraped vibes into your brand
After a scrape week, players and partners ask sharper questions about AI and asset origins. Your answers should be boring and true.
| Question | Weak answer | Strong answer |
|---|---|---|
| “Did you train models on stolen packs?” | “Everyone does it” | “We do not train on third-party packs we do not have rights to; here is our asset sheet” |
| “Is this MeshPart from Open3DLab?” | “Maybe, old project” | Source URL + license + date imported, or replaced |
| “Are you fine with platform crawlers?” | Shrug | Point to your public license + platform ToS you accepted, separately |
R3 — Upload and size gates still exist
Scrape discourse does not delete Roblox upload limits or Meshy remesh discipline. If you still bridge AI meshes into Roblox, keep the 20 MB remesh refusal and the remesh worksheet in the same week plan. Provenance without size discipline still fails publish.
R4 — Communication template (creators)
Pasteable, plain language:
We read Open3DLab’s Oct 26 report and Roblox’s Oct 28 statement via GameDeveloper. We are inventorying external packs in our live experiences this week, gating or replacing anything we cannot provenance, and we are not treating one decommission claim as a forever training policy. Our pack licenses stay posted on the download page.
License lines worth putting next to the download button
This is not legal advice. It is a clarity checklist so your stance is readable by humans and crawlers that bother to look.
| Element | Why it helps this week |
|---|---|
| SPDX or named license | Removes “mystery ZIP” ambiguity |
| Commercial / Roblox UGC allowed? Y/N | Stops silent redistribution fights |
| AI training / dataset inclusion allowed? Y/N / contact | Makes your stance explicit after scrape headlines |
| Adult content flag | Matches how Open3DLab framed risk |
| Contact for permissions | Gives good-faith requesters a path |
If your counsel already drafted language, use that — do not invent conflicting Discord legalese. If you have no license line, add one before you argue about scrapers on social media.
Developer pipeline — receipts you can keep
Working teams should treat this like an incident response lite, not a vibe thread.
Evidence pack (store in your repo or Notion, private)
- Links: Open3DLab post, GameDeveloper article, any Roblox Help / DevForum follow-ups that appear later.
- Your inventory CSV export dated this week.
- Screenshots of Terms / license pages as of the lock day.
- List of live Roblox asset IDs touched.
- Decision log: KEEP_PUBLIC / GATE / UNPUBLISH / REPLACE per row with owner initials.
Verification commands / checks (practical)
You do not need a fancy scraper to verify your own surface:
- Hit your own pack URL logged-out; confirm gate behavior.
- Confirm
robots.txtover HTTPS returns 200 and expected Disallow lines. - Confirm CDN logs show whether anonymous ranged downloads are possible for masters.
- In Studio, search for MeshIds imported this quarter; spot-check three random ones against the sheet.
Failure modes
| Failure | Symptom | Fix |
|---|---|---|
| Inventory theater | Sheet exists, live still has mystery meshes | Block publish until R1a passes |
| Statement worship | Team stops all host work because “Roblox said unused” | Re-run H1–H3 anyway |
| Panic unpublish | Nuked buyer access without migration note | Restore from backup; communicate |
| License fanfic | Discord “AI ban” contradicts written Terms | Align text with counsel |
| Scope creep | Rewriting entire UGC pipeline in 48 hours | Finish week locks first |
What changed for micro-studios this month
October 2026 already had Roblox creator-roadmap and discovery-measurement chatter. The scrape week adds a different pressure: open asset commons and platform AI agents collided in public, with adult content as the accelerant. Micro-studios feel it as:
- Partner diligence asking about training data and UGC sources.
- Hosts tightening anonymous downloads (good) and sometimes breaking legitimate bulk backups (annoying — plan mirrors).
- Players reading “Roblox scraped NSFW models” headlines and asking your Discord if your game is “AI stolen.”
Your job is not to win the HN thread. Your job is to have a sheet, a license line, and a calm answer.
For broader framing on AI practice in games, skim AI ethics in game development after you finish the week locks — ethics chapters do not replace the inventory.
Company / diligence appendix
| Diligence question | Evidence to show |
|---|---|
| Are you aware of the Oct 2026 Open3DLab incident? | Yes + dated links |
| Do you use Open3DLab / SFMLab / SmutBase packs in production? | Inventory rows Y/N |
| What is your AI training data policy for third-party assets? | Written policy snippet |
| Did Roblox’s statement change your risk rating? | Note: decommission/non-use claimed; residual crawler risk remains |
| Who owns the lock list? | Named role, not “the Discord” |
Cost/ROI: one afternoon of inventory usually beats a week of partner email. Security/privacy: adult-pack exposure is reputational and compliance-adjacent depending on your market — treat it as such without sensationalism.
Monday schedule (print this)
| Block | Owner | Outcome |
|---|---|---|
| 0:00–0:15 | Lead | Read two primaries; no secondary outrage tabs |
| 0:15–1:00 | Art / tech art | Inventory CSV draft |
| 1:00–1:30 | Host admin | H1 rate limits + robots check |
| 1:30–2:00 | Lead + counsel async | License line decision for public packs |
| 2:00–3:00 | Experience owner | R1 provenance on live MeshParts |
| 3:00–3:20 | Lead | Three-line team note posted |
| Friday 20 min | Lead | Re-check for Roblox follow-up posts; update decision log |
Opinion spine (quotable)
Stop treating a single decommission statement as a forever free pass to leave every pack anonymously downloadable.
Stop pretending robots.txt is a lock.
Stop shipping live Roblox content whose mesh origin you cannot name.
Do inventory, gate, license, and provenance this week — then argue policy with receipts.
Common mistakes
- Rewriting Open3DLab’s post into “Roblox trained on NSFW.” The host assumed training motives; Roblox denied use. Quote both.
- Ignoring SFMLab / SmutBase scope. The crawl was multi-site in the host report.
- Only locking adult packs while leaving “do not redistribute” SFW packs wide open. License still matters.
- Punishing your own buyers by deleting paid files without a migration path.
- Waiting for perfect Roblox documentation before starting the inventory.
- Confusing Meshy remesh with scrape response. Different gates; both can be on the same Monday list.
- Posting legal threats you will not file. Noise without process wastes the week.
- Assuming private Discords are immune. Different risk, still worth provenance for anything you later upload publicly.
Key takeaways
- Open3DLab reported a Roblox-labeled crawler took ~145.5 GB across Open3DLab, SFMLab, and SmutBase on Oct 15–16, 2026.
- On Oct 28, Roblox said via GameDeveloper the agent was decommissioned and the data was not used, including for AI training.
- That statement is a dated claim about that agent and that gather — not a universal future guarantee.
- Hosts should treat robots.txt as signal, and pair it with rate limits, auth, and clear Terms.
- Creators shipping on Roblox should inventory external meshes and remove or replace anything without provenance.
- Put a readable license + AI-training stance next to downloads you keep public.
- Adult-tagged full ZIPs are the highest controversy surface this week — gate or remove anonymous access by default unless counsel says otherwise.
- Keep Meshy / upload size discipline separate but concurrent if you still bridge AI meshes.
- Diligence answers should cite primary URLs and dates, not Discord summaries.
- Finish a Friday re-check for follow-up statements before you close the incident note.
- Panic-unpublish without backups creates a second outage; migrate deliberately.
- This URL is a lock list, not a verdict on Roblox’s entire AI roadmap.
FAQ
What is the Roblox 3D scrape people mean in October 2026?
Open3DLab’s October 26 post describing a Roblox-labeled crawler downloading about 145.5 GB of models from Open3DLab, SFMLab, and SmutBase on October 15–16, including adult content, reportedly ignoring robots rules, Terms, and licenses.
Did Roblox say it trained AI on that data?
No. Roblox’s October 28 statement to GameDeveloper says the agent was decommissioned and the gathered data was not used for any purpose, including training AI models.
Does Roblox’s statement mean creators can ignore the incident?
No. It addresses that agent and that dataset claim. Hosts and creators still need inventory, licensing clarity, and reduced anonymous download surface.
Should I delete all my Open3DLab uploads today?
Not blindly. Inventory first. Gate or remove high-risk packs (adult full downloads, exclusive mirrors, unclear licenses). Keep a backup and a migration note for buyers.
Is robots.txt enough protection?
No. Open3DLab says the crawler retrieved robots.txt and still proceeded. Use rate limits, authentication, and signed URLs for sensitive masters.
I only publish on Roblox — does this affect me?
If you never used those hosts, your scrape exposure may be low. You can still get diligence questions. Provenance your live meshes and keep a calm, factual team note.
How is this different from Meshy Roblox upload limits?
Meshy/Roblox posts about the 20 MB remesh path are upload-size gates. This article is about a scrape incident and weekly locks for hosts and provenance — different problem, same week possible.
What should companies put in a risk memo?
Date-linked citations to Open3DLab and GameDeveloper, your inventory status, your AI-training data policy for third-party assets, and residual risk that future crawlers are not forever ruled out by one statement.
Where do I learn Roblox Studio basics if I am new?
Start with the Roblox Studio guide. Come back here for the scrape-week lock list after you can open your experience and list MeshParts.
Can I paste this into Discord?
Yes — use the communication template and the Monday schedule. Link the two primary sources. Do not paste legal threats you have not cleared with counsel.
