    Hi! Is it possible to have a model another place than Sketchfab computers (for example on my own computer or a company's computer)?
    Say company X wants to store a model on its own computers for security reasons. The idea is that customer Y would go on company X's website to view their model using Sketchfab viewer. Is this remotely possible?

    @wood_dragon - At the moment, all models must be uploaded to Sketchfab for processing, and we don't license the viewer technology for others to host.

    Hi, I am going to use 3D models in the classroom and assign these models to individual students. I would like students to be able to add annotations and text to "their own" models. Is their anyway to do this without giving them my credentials? Assigning a password won't give them permissions right?

    @elearning - Hi, sound great. We don't have a system like that yet. The best thing to do is have them create their own accounts or create new accounts yourself for them so you can keep your own credentials safe.

    Hello, I just want to point out that after turning a model as private, with/out password on a chrome computer, after I log out and go to the model page I immediately see the product loading and working just fine. I've tested the link in IE and it properly prompts for the password. I haven't reset cache on Chrome as I'm doing some web dev at the moment but I shouldn't have to, I think. I can imagine this being a problem to someone wanting to hide a model from coworkers (think coworking spaces) or family (think surprise!) ...

    @cgartefacts - Making a model Private just means that it is unlisted. Anyone who knows the URL can see the model. This is the intended behavior. If you want to keep the model hidden, you should add a password. I'm sorry that this wasn't clear. I will update this article to be more explicit.

    @James. What about letting 25 students log in simultaneously on my credentials (and changing the password afterwards)? Can it be done?

    @elearning - You could do that, but if they log out after you change the password, they won't be able to log back in. Maybe you could create a "dummy" account for this purpose?

    Thanks James. Okay. That will work, because I want them to edit the models under my supervision during class. As long as multiple logins are allowed they can mess it up as they want. A duplicate (backup) account would not be a bad idea, but that probably won't be possible with the click of a button right? (I have over 70 models up).

    Well, we could make the existing account the "supervised" account, then you can create a new personal account. Or we can move the models for you. Can you please send me an email? support@sketchfab.com - It will be easier for me to work with you that way.

    Prejudice a question if the public private model password when I insert it in the wordpress site, a password is required to who wants to see the site in wordpress? in more private links to the model, it is indexed by the engines? thank you very much

    @IVAR The password is always required, and the model will not be indexed by search engines.

    James,

    If I want to make a model available for a certain site e.g (my site) , and someone else embed it to their site, is possible to give direct access to my site but still have the password if somene tries to copy the url?

    @brvr - Not at the moment. If you add a password, the password will be required everywhere.

    Someone steal models from sketchfab.
    Look at this:

    @steplont - Your original files are never exposed unless you enable download. Our viewer serves a compressed version of the mesh. However, once the 3D data reaches your GPU, it is available locally. This is required for our viewer to work. This is really no different than any other media published on the Internet; it's trivial to rip images, audio, and video from most sources. In fact, ripping 3D is harder.

    That said, we are working on some features to make such techniques harder. In theory, it's possible to make automatic ripping VERY difficult. However, this would hurt performance and stability of the product. You can follow some more discussion here:

    Is it possible to "livetrack" unauthorized access to certain outputs of WebGL/the viewer and immediately cut access once it's been detected?

    @jqw207 We occasionally ban IP addresses of of abusive or spamming users, which blocks their access to the site completely. We also monitor ripping tools that work at the level of the browser / viewer change our code to break them when they are detected.

    how about "Add Watermark" option to prevent easy video recording / screenshoting for reverse-reconstruction of models?

    Just found one of my models for sale on turbosquid, AGAIN!!
    Twice this has happened! :(
    Ive lost faith in sketchfab now and have removed most of my models.
    The fundamental weakness of this site is that your model, when viewed, is temporarily downloaded to the graphics card of the viewers device (openGL)
    From there it can be extracted using freely available software and then sold on 3d model vendor sites such as turbosquid or cgtrader
    Seriously, how can sketchfab expect to create a viable 'store' when the back door of the store is wide open fior thieves?
    Seems like the whole platform is built on sand.
    Jump off before it sinks

    Hello,

    I'm really sorry to hear that. One of our main projects for 2021 is to implement new security features into the viewer. This can be at the technical level such as "encryption" (more like obfuscation) to make it harder to read files from the browser and reverse engineer the model from the GPU, as well as more user choice such as automatically watermarking models and textures used in the viewer.

    Our Store and Community team is also ready to help in any way they can with takedown requests and legal action.

    One of my 3D model on Sketchfab was stolen by an Indian guy then he sell it RenderHub. I forced him to remove the model from RenderHub with assistance of the RenderHub's admin and series of my evidences provided to both of them. The thing I want to say here is: there was only Sketchfab have my 3d models from which the Indian guy could rip and steal even I never configure all my 3d model fee download!? Is it safe to use Sketchfab anymore?

    dmd_hn from my past experience working with Sketchfab models and making use of Sketcfab's support, you will have to take Sketchfab as a small startup, which for some years is trying to be profitable by removing many previously free features/benefits. So, unless you're working on McLaren custom parts division or some other high NDA scenario you can use it as it is without any expectations of them genuinely caring about customers' specific needs. As long as what they're doing works for the bulk of their users, they think it's fine. 


    So totally safe unless you need rigorous safety, that's my opinion.

    Hi there,

    dmd_hn - we are actively working on several new, stronger techniques to encrypt and protect models from such "ripping" tools.

    cgartefacts - I'm sorry you feel that way. We are trying to build a sustainable business. While you are correct that a high profile client will often take priority for new feature requests, I believe we still offer a ton of value to the community at large. We never limit rendering quality or 3D features to paid accounts, for example, and our Community and Support teams works hard to help all our members as much as we can.

    There is an infinite number of things we could build or improve, but we are a small team and need to prioritize the goals that help the most people.

    No sadly your model isn't safe at all.
    Dont upload anything that you wouldnt also give away for free.
    If you have a model you care about and dont want ripped & sold then best to just post up renders somewhere else
    Its a real shame but not much can be done about it :(
