    I think it's really important to get support for this in place. Both Github and Gitlab support it now. I've been hosting all my development on Github with it. So I can't use Cloud Build without it.

    It's also super easy to install....

    Hi there,

    This is something that's definitely on our radar, and while there is currently no ETA you are correct in that it's pretty straightforward to install. Once we have built support for LFS into our infrastructure, I'll be sure to post an update here to alert you and everyone to its availability. In the meantime, for anyone else looking for LFS support, please post a vote at our feedback site as it helps our team gauge demand for new feature requests from the community:

    https://feedback.unity3d.com/suggestions/git-lfs-large-file-support-for-unity-cloud-build

    Stay tuned!

    Regards,
    -Chris

    This issue is clearly the most voted suggestion that the Cloud Build team has in the feedback system. Given this and your suggestion that it's straightforward to implement, why is there no ETA or roadmap item?

    Our team can't use Cloud Build without Git LFS. Would absolutely love for you guys to add this feature.

    Any updates on this? Relatively simple to implement and a lot of us here are waiting for this, sounds like it should be a feature pushed out on a very high priority. Any timeline?

    Hey all,

    We've been actively working on Git LFS support, as it's the highest rated item for Cloud Build on the Feedback site. Some early experiments are showing promising results, so right now it's possible that your LFS-enabled project will work. If you do give it a try, please reach out and let us know how it goes. Keep in mind that LFS is not technically supported right now, so this is targeted more at existing users of LFS that are comfortable with it.

    Some basic guidelines:
    • You must have SSH access to your projects at an account level (GitLab doesn't currently support SSH authentication with LFS).
    • Deployment keys are not supported on GitHub.

    Hi @unitychrism :)

    Just reporting in to confirm that whatever early experiments you're doing are working for our project! :) Thanks for adding in LFS support so quickly! :)

    Yes, positive feedback! :) Glad to hear it, and would appreciate feedback from any others that configure their LFS project in Cloud Build. There should be more information available in the near future, which I will also link to here.

    Hello again @unitychrism :)

    We got an LFS-specific error in our latest Cloud Build. It's complaining about a file that it had no trouble with in the past, which is weird. Here's the relevant portion of the log:

    The Cloud Build system took just over 50 minutes before hitting that error. I'm attempting a new build right now just to see if it can recover on its own. I wonder if it just doesn't like how many assets we have stored via LFS?

    Edit: Just for reference, here's our .gitattributes file:

    Second attempt at a build failed, as well :( But on a different file this time.

    Is there anything we can do to workaround this? :(

    Hi there,

    It looks like you were able to build successfully after these errors yesterday. As part of an update next week, there should be an improvement in LFS logging that will allow you to view the specific error being encountered. If this continues to happen sporadically, please let me know via direct message.

    Yes, third attempt (after waiting about half a day) was a success :) Maybe the Cloud Build system was just having a bad night :) Thanks for the reply!

    I'm considering enabling LFS for our current project to take advantage of Unity Cloud Build.
    Is this officially supported yet?

    When will this be implemented officially? We have to move over to LFS as soon as possible.

    Is that even possible to write a game without git lfs??? Repos are quite big (my current over 35GB) so it's unclear how should we use a continuous integration that does not support that???

    And you hope that I'm gonna pay a subscription?

    OK new question. Have you guys looked into updating Git and LFS?

    According to my error log you are still using Git v2.6.6 and LFS v1.1.1.

    There have been some LFS specific improvements with a Git v2.8.x and LFS v1.2 combination. Using it locally for a few weeks now.

    Here's an article from a SourceTree dev about some of the speed improvements:
    https://developer.atlassian.com/blog/2016/04/git-lfs-12-clone-faster/

    Using the new "git lfs clone" command would probably be a speed and stability improvement for Cloud Build.

    Hello,

    Am I doing something wrong or Unity Cloud build and LFS is not yet operational / is experimental?

    I have a Github repo with LFS, and I have have setup SSH keys.
    Previously I used Bitbucket git successully but without LFS, until I hit their 2GB hardlimit...
    Now, I tried to move to github for their LFS support, but I am stuck here...

    I get a bunch of errors and a failed build

    [Unity] FSBTool ERROR: The format of the source file is invalid, see output for details.
    [Unity] ImportFBX Errors:

    [Unity] Updating Assets/max/Materials/BACKPACK2NORMAL.PSD - GUID: 02f73260494e6f94eb3054045a56269a...
    [Unity] Could not create texture from Assets/max/Materials/BACKPACK2NORMAL.PSD: File could not be read


    Can give more details upon request....

    regards

    Greetings @unitychrism,

    We are happy to see that Git LFS is being integrated. Here are some LFS related issues that are keeping our builds from finishing / starting.

    LFS Smudge Filter Bug


    1315: fatal: Assets/Audio/Games/InOtherWords/Level 4/club.iowclue.en.wav: smudge filter lfs failed
    1316: git-lfs/1.1.1 (GitHub; darwin 386; go 1.5.3; git 7de0397)
    1317: git version 2.6.6


    It doesn't always fail on the same file however, for instance on a different build target it fails on:


    1031: fatal: Assets/Audio/Games/Glyphs/Short Recipe/glyphs.shortrecipe.s5.audio.2.en.wav: smudge filter lfs failed
    1032: git-lfs/1.1.1 (GitHub; darwin 386; go 1.5.3; git 7de0397)
    1033: git version 2.6.6


    I have cloned this repository successfully on other devices, so I know that the files exist. It may be a matter of updating the LFS version.


    Thanks,

    Also getting regular smudge filter errors. It's a known problem with LFS solved, partly, by the resume feature in LFS 1.2+.

    As Unity Cloud doesn't have a 'resume failed' feature I'm not certain what the solution is.

    Same thing here... trying to get data from our selfhosted Bitbucket Server.

    But I also get a certificate error, I guess because we usa a selfsigned SSL certificate. I thought that for a connection via SSH that certificate would not be used, but seems like LFS objects are transfered via HTTP(S).

    Ok, forget my previous post. As the error stated the IP was not included in the certificate.

    My solution which works now: using a subdomain and Let's Encrypt to generate the SSL certificate and everything seems to work fine.

    @gonzorob, thank you for pointing out the resume functionality in LFS 1.2. I'll look into us updating our version of Git LFS to provide that functionality, as it likely will help with smudge filter errors you'll see if there is any sort of hiccup in the LFS pull.

    @DerWoDaSo, I certainly appreciate you posting about your solution using Let's Encrypt to generate a valid SSL certificate for your system. To provide some context, while Git LFS communicates via HTTPS the only way we can authenticate for you against the system is to use LFS' inbuilt authentication via SSH since we do not handle user/pass information for Git repositories.

    Will come back to this thread when I have more information, thanks for your patience.

    Git LFS 1.2.1 is now available in Cloud Build and I am running through some test builds myself. Please respond to me directly with a Cloud Build build attempt link if you encounter issues while building with LFS.

    @Afropenguinn GitLab CE 8.2 is out now, which should support SSH authentication for LFS files... I saw your post in their forums. I am currently updating, hope it will work.

    Git LFS 1.2.1 is still failing for me. I was able to clone the project on another computer successfully.

    24: fatal: Assets/Forest Bat/Animations/Forest Bat@attackbite.FBX: smudge filter lfs failed
    25: git-lfs/1.2.1 (GitHub; darwin amd64; go 1.6.2; git 79bedeb)
    26: git version 2.6.6

    Anyone able to do cloud build with LFS successfully? What is your setup like?

    Our project is also getting the "smudge filter lfs failed" errors when we try to build using the Unity Cloud Build.

    1833: Error downloading object: ModularCityAlleyPack/Assets/Walls/Meshes/Wall_D_Brick_Window_J_2x.FBX (cfae39034d62a1f719ec9901be67bf67b85a960aff945019ba55588abdbed13d)
    1834: Errors logged to /BUILD_PATH/strata.vr_studio.default-windows-desktop-64-bit/.git/modules/ModularCityAlleyPack/lfs/objects/logs/20161119T175014.075029395.log
    1835: fatal: ModularCityAlleyPack/Assets/Walls/Meshes/Wall_D_Brick_Window_J_2x.FBX: smudge filter lfs failed

    It might be related to how large our project is (8+ GB) that we tend to run into these errors nearly every build on the Unity Cloud Build. I didn't noticed any similar errors in our local clones/builds but that might just be because we don't have to re-clone our repository for every build.

    We get a "smudge filter" failure when new files have been added via Git LFS, it usually needs several buildings to get it through to be successfuly, each one that fails falls over on a different LFS file (further on from the previous fail)

    We are using BitBucket cloud with LFS enabled and we find even on our PC's that it can be quite slow to download sometimes, so it might be a timeout issue perhaps?

    It could just be a matter of updating LFS on the build servers. I get the same smudge filter issues on older versions of LFS, but haven't had problems with 1.5+.

    Any news about this? I´m using Visual Studio Team Services with GIT to host my project and Unity Cloud Build is reporting a " smudge filter lfs failed" error.

    Thanks!

    We also have a problem involving git lfs clone.
    We are occurring `dial tcp: i/o timeout` error while downloading 3000~5000 files.
    We have 10000+ lfs-managed files and we've never succeeded git clone.

    The failing files differ each time we build.
    The error messages are always `dial tcp: i/o timeout` for every build.


    Is it helpful to PM our project name for someone Unity Technologies?

    I'm currently having the same issue as a couple of the other people above me it seems. Here is the Full Log of my build in Unity Cloud Build:


    I was wondering if I could get some support?

    It seems my builds are not attempting to pull LFS assets, leading to build failures about not being able to load textures or find namespaces that are implemented in dlls (both of which are file types we manage with LFS). Can I get some support?

    Update: Retried again today (same commit SHA) and it has pulled 1.5 GB instead of 300 MB. So it appears like it is at least getting all the code again.

    I'm also getting the same "Error downloading object" with LFS. Have sent you a pm, @SophiaC .
