Thoughts on Sketchfab to Fab migration announcement, September 2024

Last edited 10 March 2025

Intro

A few people have asked me about the most recent update regarding the transformation of sketchfab.com to fab.com, and while I no longer work for Sketchfab or represent them or Epic Games in any way, I’ve tried to make some sense of the recent announcements made by them that will impact all current Sketchfab users, including the cultural heritage community. All in all, it feels like a bit of an end of an era ^[a][b][c][d]🥲

Update 10/03/2025
Scholars from Maastricht University have published “And Now What? Three-Dimensional Scholarship and Infrastructures in the Post-Sketchfab Era” link:

“The transition of Sketchfab, a widely used platform for hosting and sharing 3D cultural heritage content, to Epic Games’ Fab marketplace has raised concerns within the cultural heritage community about the potential loss of years of work and thousands of 3D models, highlighting the risks of relying on commercial solutions for preservation and dissemination.”

Update 20/12/2024

On 25 November 2024, the IIIF 3D Community Group held a call with representatives from Epic Games to discuss the future of cultural heritage content on the platform. Notes can be found in this document here.

Update 19/11/2024

Epic Games is holding a live video stream on the 22nd Nov.

"Join the Fab team on November 22 at 10am ET to discuss the recent release of Fab, see the product roadmap and ask the team questions! Plus, get a sneak peek of the Quixel content roadmap and an update on Bridge from the Quixel team:"

FAB Roadmap

https://dev.epicgames.com/community/fab/roadmap

“Asked a question what the plan is for Sketchfab, and they are saying they want to replicate the features on FAB (community, viewing and distributing free content, businesses sharing files to view) - they say they don’t take away functionality from Sketchfab until FAB can replicate them. Until then, Sketchfab will keep existing. Cultural Heritage licenses for non-commercial use are also considered for bringing on to FAB.” via Cordula Hansen

Update 23/10/2024

• Fab.com has launched.
• Sketchfab has published a blog post: Sketchfab Update:
  What You Need To Know Now That Fab’s Live

Update 11/10/2024

Sketchfab has just sent out an additional email with the subject “Clarification on cultural heritage content on Sketchfab” a copy of this email can be found below.

Update 10/10/2024:

American folk art specialist Emily Esser has opened a petition on change.org:

Keep Sketchfab Alive: Preserve Open Access To 3D Museum Collections 

The Sketchfab Email

I don't have more info than the email (copy below, don’t worry if you’ve not received it yet it can take a few days to send out millions of emails) and blog post from Sketchfab, or the Unreal Engine announcement page, but some things are clear^{[e][f][g][h][i][j][k]}:

• Sketchfab as a whole will be winding down in 2025.
• "In 2025, we plan to stop offering downloadable content on Sketchfab."
• All downloadable paid, CC-BY, standard licence 3D content will eventually move to Fab, so it is a matter of 'when' not 'if' to move your models in these categories if you want them to continue to be available for download.
• CC-BY-SA, CC-BY-SA-NC, CC-BY-NC licensed 3D models are not transferable to Fab, but eventually won't be downloadable on Sketchfab either 🤔 there is no mention of what will happen to CC0 public domain 3D content link
• It appears there will be a period of time where 3D content from a single user will be on both Sketchfab and Fab.

What is not clear:

• What happens to non-downloadable (view only) 3D content on Sketchfab in the long run.
• What happens to private downloadable 3D content on Sketchfab in the long run (my guess is that it is not supported on Fab).
• What happens to CC-BY-SA and CC-BY-SA-NC 3D content in the long run.

Epic Developer Forums

There is also a fair amount of relevant info that is not directly included in the Sketchfab comms and I reeeaaally recommend looking at the more in-depth information over on the Epic Dev Community. There are a lot more relevant details about what is happening and will happen to Sketchfab in the future, I’ve pulled out just a few here:

• Fab is a straight up marketplace with no community layer, no word on whether that will continue at all in some form:

• Fab does not support likes, view counts, download counts, comments, collections, or follower feature link

• Not all 3D file formats will be supported on Fab link
• Not all compressed file formats are supported by Fab (e.g. RAR or 7-Zip are not supported) link^[l][m]
• "The migration process copies your 3D model data to Epic Games servers in the United States." link
• "Fab listing has a fixed list of tag [...] It cannot migrate a tag that does not match a Fab tag. The tag does not appear on your Fab listing." link
• "Sketchfab 3D models can have zero, one, or two categories, each with one level. Fab listings have exactly one category with optional subcategories." link

• Models with the Cultural Heritage & History category will be mapped to Objects & Decor 🙃

• The new Fab 3D viewer does not currently support Annotations, AR mode, VR mode, Custom backgrounds, or Custom HDRI environments link
• I suggest you take a look at the "Q: What Happens to Sketchfab Models after I migrate them to Fab?" FAQ on this page

Clarification on cultural heritage content on Sketchfab

October 11 2024

Potential Alternatives to Sketchfab^{[n][o][p][q][r][s][t][u][v][w][x][y][z][aa]}

The upcoming move to Fab for downloadable content and updates to Sketchfab will undoubtedly change the way we all use Sketchfab as well as how audiences access cultural heritage 3D on the site. While these changes may be unwelcome to some, they may also suit some aspects of heritage 3D outreach: in theory, moving open access (at least CC-BY) 3D heritage content closer to creators in the creative industries could be a good thing!

However, if you are starting to think about an alternative home for your heritage 3D content, here are some suggestions from the community^[ad][ae] (see comments as well):

Quote from Emily Esser’s petition “Petition · Keep Sketchfab Alive: Preserve Open Access To 3D Museum Collections”:

Updated text 13/10/2024

“Since its inception, Sketchfab.com, a 3D model-sharing website, has served the invaluable function of hosting and showcasing the vast digitized collections and portfolios of many museums, universities, and artists across the world.

Unfortunately, their new owners, Epic Games, intend to destroy it.

In 2025, they have announced they will remove the download function, forcing creators and users onto Epic’s “Fab,” a game development asset store that exists purely for the sake of profit. But killing the Sketchfab Store will severely harm independent artists and small businesses. There's no benefit to anyone from "Fab," except for lining Epic's pocketbook.

Sketchfab is irreplaceable. It is the service to host and view 3D models online. It provides invaluable assets, used and shared by everyone, from indie game devs to renowned institutions. Fab would happily destroy all that. Comments are disabled, forbidding users to speak to each other. Downloads will be unavailable, prohibiting the free sharing of content. Everything about this decision goes against the core of Sketchfab’s nature and its significance in our digital modern world.

This is the virtual equivalent of burning the Library of Alexandria.

But the "Fab" upheaval was delayed for a year once already. With enough active effort, we can stop it again. And we must.

Update 10/12/24: The Sketchfab Blog website is down, denying access to the specific Fab terms of service unveiled 10/1/24. However, here is a PDF copy of the email issued to all Sketchfab Store sellers (I am also a 3D artist, so I received it.) Here as well is a news article reporting on the announcement.

Read here for a discussion of the Sketchfab Store's importance to 3D artists.

Read on for a discussion of Sketchfab's value in preserving cultural heritage.

---

Five years ago, Sketchfab celebrated the massive milestone of 100,000 models in the “Cultural Heritage” collection. It’s always been clear that Sketchfab acts as a public good, not only a commercialized marketplace. Researchers rely on the availability and accessibility of these assets — and Sketchfab’s announcement made that same point: "What’s even better is that almost 20,000 of these models are available to download and re-use under easy-to-understand Creative Commons licenses, which means that this amazing wealth of 3D data can travel beyond Sketchfab to be reused in new and amazing ways.”

That is exactly what they intend to wipe out from the site.

The “Fab” announcement ominously declares that time is limited. “Free content will continue to be available on Sketchfab into 2025, before we remove free licensing from Sketchfab next year.” Out of greed or short-sightedness, Sketchfab now plans to force a massive inconvenience upon all these individuals and institutions that they once proudly partnered with.

Countless museums have already put in the vast and time-consuming effort of digitizing their collections. They, and all other users who wish to maintain downloadability, are expected to go through the onerous “Fab” migration process, which does not support the common Collada/DAE file format, erases all usage statistics, and, worst of all, rejects many Creative Commons licenses, like CC0, that are used by museums such as the Smithsonian: “Models that are currently licensable under CC0, CC BY-ShareAlike, CC BY-NonCommercial, or CC BY-NoDerivatives cannot migrate to Fab under those license types, as those licenses do not exist on Fab at this time.”

There is no benefit here. Epic wants to convince users that the site’s impending doom is a good thing, but “Fab” has received nothing but widespread outcry. Users have reported that the transition process is filled with technical failures and deeply demoralizing. “Educate, inform and add metadata to your content with Tags and Descriptions,” says Sketchfab's page advertising to museums — data that would be lost when starting over on the “Fab” store. And that very same Museums page promotes the download option. They know how important it is.

Why should academic research materials be forced onto a marketplace? And why should artists and model sellers be forced to re-set their statistics and start from scratch?

Epic Games claims this is an improvement to the site. Do not believe it. There is nothing wrong with Sketchfab in its current form, and its destruction would be a massive mistake for the sake of profit. Epic will lose nothing by leaving Sketchfab intact. But if this site is destroyed, the world of digitized content would lose everything.

Individual users may be powerless to stop the ruination of Sketchfab in the face of Epic’s attempt at a market monopoly. But I believe that a coordinated effort, spearheaded by its massive user-base, including research institutions, could save it. Please sign this petition, and send the link along to anyone you know. Thank you very much.

Notes from IIIF 3D Community Group Call with Epic Games 25/11/2024

Monday 25 November (IIIF3D/Epic special Meeting)

Present

• Thomas Flynn (The Spatial Heritage Review)
• Ronald Haynes (University of Cambridge)
• Mike Boyd (University of Edinburgh)
• Dale Utt (Cleveland Museum of Art)
• Ronald Haynes (University of Cambridge)
• Jocelyn Triplett (MorphoSource - Duke University)
• Abby Crawford (AC)
• James Green (JG)
• Gabriel donofrio (GD)
• Adi Keinan-Schoonbaert (British Library)
• Liam Green-Hughes (British Library)

AC - lots of great questions in the document, in many cases Epic dont have the answers yet - still digging into the details

JG - Epic have just shut down 4th marketplace - focusing on making Fab the best marketplace it can be, once marketplace features are stable, will move on to better distribution of free content

• Expanding CC licenses
• Improving and optimising onboarding for “free content only” users
• Sketchfab will remain available throughout

Questions

• Will Epic share how many museum/education/science users/3D models there currently are?
  
• Is a public sketchfab.com / fab.com feature roadmap available?
• Fab Roadmap available at Roadmap - Unreal Engine | Epic Developer Community
• JG - no roadmap available yet for community features, in the very early stages of designing the roadmap, next 6 months will be totally focused on designing marketplace
• AK-S - note that current roadmap very feature focused, and not strategic direction; (acknowledging importance of other communities) would be positive
  
• What is the timeline for updates:

• Sketchfab shutdown.
• Fab feature additions.

• CC0 and other CC licences

• Will such licences be added before Sketchfab turns off downloads?

• Annotations.
• JG - 3D team committed to rebuilding annotations, but down the line when private viewing is on the table for development - note that rebuilding annotations to allow seamless transfer expected to be a challenge
• Expanded tags / categories.
• Collections
• Followers
• Likes or Favourites
• Comments

• If certain features are not viable in Epic’s future offerings, is there interest in helping the CH to migrate content elsewhere in a timely manner? (See ‘data carry out’ suggestion below).

• JG - APIs and means to allow download of everything someone has uploaded including, annotations (though not convenient), GLTFs generated on Sketchfab side (any changes to materials included in GLTF, even if not present in file originally uploaded), recognition that  a “download all my data” button could be a good approach
• JG - while lighting, materials and some of PBR channels are different, it’s not anticipated from Epic side that this will cause significant issues (feedback from KH that there are instances where PBR channels will be very important - concern that efforts to ensure models look great in sketchfab may not carry through to new viewer)
• AK-S - note all metadata is important (comments, likes, followers, 3D file metadata)
• JG - Fab keen to ensure 3D file metadata is retained.
• JG - Epic wants to preserve social elements and counts (views, likes, followers, collections, comments). Though comments may be a challenge due to privacy concerns

• How will audiences interact with heritage data on Sketchfab/Fab in the future? I.e. What will their experience be in comparison to using Sketchfab today?

• JG - Recognise lots of value in the social elements - while front page of Fab will be marketplace focused, Community features are expected (down the line, no current roadmap)
• JG - In the future there will be a button to convert and move all content across to private library in Fab (mirroring model for sellable content). Anticipation is this will see close to a 1:1 experience between current Sketchfab and Fab

• How long will Sketchfab.com links/embeds remain live?

• AC - Free and view only content is staying as it is for now
• What will be the process for redirecting to Fab URLs?

• JG - If content added to fab - redirect will be added
• JG - epic not in the business of breaking links across the internet, suspect Sketchfab links will remain functional for years to come
• Embed links will not be broken

• How long will Sketchfab.com APIs remain live

• What will be the process for redirecting to Fab URLs?

• JG - If content added to fab - redirect will be added

• What will happen to orphan data?

• Is there a data retention policy?
• Would Epic Games be open to help identify ‘at risk’ cultural heritage data and support community efforts to capture a backup?

• Might the Sketchfab 3D viewer be open sourced?

• JG - Don't think any world in which legacy viewer will be open sourced

• GD - could there be a situation in which Sketchfab offline viewer could be set up,

• JG - something requested historically, but hasn’t been implemented/developed (“anything is possible, nothing is free”)
  

• The Sketchfab Blog Cultural Heritage Spotlights are a valuable resource for the heritage community - will they remain available in perpetuity?
  
• Will ‘Sketchfab Labs’ features like video and GIF export, and the screenshot maker be reinstated at some point?

• RH - Are Epic open to working toward compliance with IIIF 3D standards?

• JG - sounds interesting, keen to review whats available info wise and start the conversation internally within Epic

• LG-H - Fab very much currently a marketplace, how much attention is being paid to non-marketplace users in design plans?

• JG - foreseeable future is focused on marketplace, longer term there is aspiration to include a “different place on Fab” that wont be so focused on marketplace aspects

• GD - follow up comment to highlight some collections are sensitive, so any route to be able to prevent eg. ad banners in these cases would be very positive

• JG - vision for this is following upload you can get a private url, this would function similarly to Sketchfab private URL (clean viewer for asset free from any call to actions)

• KH - appreciate Epic's recognition of the value of the community features, looking ahead to potential benefits on Fab.com, some other platforms are looking at derivative generation, Is anything like that currently on the roadmap?

• JG - not currently on a roadmap but there have been conversations around this within the company (making Quixel Megascan pipeline tools available across other content)

• GD - are there routes for cultural heritage users to incentivise development of tools we require

• AC - a clear, concrete statement of what the community needs and what benefits these will provide will prove useful to justify development. Knowing how things fit in to what we do and how Epic can be a part of improving this will be a positive.

• TF (follow up) - huge library of content, having Fab as a route to distribute will prove useful. Clean, useable data (in eg Fortnight, UE etc.) from cultural heritage orgs likely a positive. Is there a benefit to cultural heritage orgs investing in what could be done with our data by other Fab/Epic users?
• KH (follow up) - cultural heritage hackathons potentially a positive

• AC - community engagement activities a positive
• JG - no world in which Epic/Fab dont want to remain the home for 3D data for a multitude of uses - but small team within Epic, prioritising essential

• AK-S - note that cultural heritage orgs provide a way in to engagement with 3D data, keen not to feel like too much of a marketplace

JW - would sketchfab be open to expanding export to include annotations in public data API, to aid with interoperability between viewers

JG - adding annotations to public data API is a reasonable ask and relatively easy win

TF - great to continue these conversations and plan to revisit some of these topics (both via IIIF3D slack channel and forging connections where possible.

Community List of Most Valuable Sketchfab Features for Cultural Heritage Users

These features are especially relevant for both publishers CH content, as well as end users/audiences.

• Commitment to supporting cultural heritage accounts with free subscriptions.
• Hosting: asset data + 3D viewer.
• Community features: profile page, followers, likes, comments.

• Increased ‘discoverability’ for general and creative audiences.

• Embeds / easy to use 3D viewer.

• Data optimization.

• Annotations.
• 3D Editor.

• Shader options.

• Collections.
• Tags.
• A “Cultural Heritage & History” category.
• "Museum/Educational/Scientist" user categories.
• Additional open licenses, public domain dedication.
• Data, download, and viewer APIs
• Usage stats: views, downloads, likes.
• “Utility of 3D” features i.e. view the same model online, in VR, AR, capture screenshots, video, GIFs.
• Private models

Suggestions from IIIF Community

• A specific commitment to ongoing support for the work of heritage organisations.
• Guarantees regarding long term support for features e.g. annotations.
• A ‘data carry out’ feature/service to help organisations retrieve:

• 3D data.
• Metadata (Descriptions, tags, annotations, lighting, comments).

• Maintain some kind of community layer so that organisations can keep in contact with their audiences.
• In the future, Epic’s platform(s) could support data import and export under the IIIF 3D spec.

• Would this potentially make a good proposal for an Epic Megagrant?

• Better integration with RealityCapture/RealityScan for 3D scan metadata e.g. for automated processes that make additional metadata available alongside published 3D models.
• Epic could migrate public domain heritage data to Fab themselves.
  
• A ‘school/educational friendly’ Fab gateway featuring vetted content.
  
• Web accessibility compliant 3D viewer.
  
• Support for Digital Object Identifiers (DOIs)
  
• Trusted data repository accreditation e.g.

• CoreTrustSeal 
• Digital Preservation Coalition 
• World Data System
