I've messed with a few of the listed non-working lenses and was able to get them running successfully. Unfortunately, it required modification to the lens (and thus unpacking + repacking). There is a javascript file inside (e.g. File366.js) with a Not sure if there's a cleaner way to do this, there appears to be some sort of configuration system that this default value is used with if not set. If we could hook into that, or access and modify the javascript environment (or even override the detected platform or device model), a more generic fix might be possible without needing to patch individual lenses. |

Hi @ptrumpis & @ghalta22 , I am curious on how to get the Snap Camera client application to validate & use an updated lens after unpacking & repacking it.
Note: I even tried to host the updated lens on my internal server with a new unique id, same result. |

Never mind, I got it to work. I had updated the Zstd size field of the file's header, but didn't update the Compressed size field (@ 0x1C) although both fields carry the same value. After updating Compressed size too it works perfectly fine. |

Comment on your stepsI never tried the process myself, but judging by your steps you would have to rebuild the header "a little bit" more:
Hex offsets that would have changed:
How I think it should be done (untested)The best way in my opinion would be to upload the zip package with modified files to the server, not the LNS file If you prefer to have a re-packed LNS file there is a python tool https://github.com/cvirostek/snapchat-lens-blender-io/ Edit: |

@ptrumpis thanks for the prompt response! Yes, I realized minutes after my original post that there are actually 2 entries in the header that define the size of the zstd and I had updated only one. Regarding the rest, I made sure to keep the file structure and uncompressed file size exactly the same as the original after my update. |

I've been keeping track of all the lenses that don't work by SnapChat, here is an updated, revised List: would be nice if one person can verify if these indeed are not working. Be careful of similarly named ones not by snapchat. Intense Look Note: @ghalta22 If your workaround gets these lenses to work, please help us out. THANKYOU if you do! |

Holy shit, you got alot of these to work. Thanks a tonne! You've given the entire snap camera community so much aid, much appreciated! For your further convenience I noticed and wrote down some things: 1.Some of the ones you claim aren't working actually work for me: Sibling lenses for example have a second copy available through search that work. If you'd like I can double check all of them for you and report it in a few days.

Lens ID: 58130770949 But it works on my system without patching. |

Thanks! that's super helpful and the video does still help. Since it's working on your system it's obviously not the lens and must be something specific with my when i try to select the lens it never loads in snap camera, just a circle that spins and spins. (so far only happening to this one lens). I noticed that for this lens it never makes a {LENS_ID} folder in the /cache/lenses folder and if i take a look at the log located in /Snap Camera folder it says... |

You need to apply a signature patch. It's similar to an iPhone Jailbreak. |

Hey all, thanks for all the time and effort you guys have put into this project. For the life of me, I cannot get this lens to work. https://www.snapchat.com/lens/0bfb145fa7b4445198821eaefc0fa7f6?type=SNAPCODE&metadata=01 I have tried all the steps and workarounds I have found but it doesn't load. Could someone look at it for me and see if maybe I just did something wrong? There are a few comments at the bottom of the log where I attempted to use the lens but I don't know what they mean. Thanks so much!! |

Hi everybody, I am hardy try to make this lens work: https://www.snapchat.com/lens/a375b6d69d0c4feda05a84e0ab58e471?sid=a469e440385c4d19b03a5f690983015c&invite_id=EI72yt2P I have the signature patched snap camera. at first time the log sais that the it failed to download an asset named RND-802_fashion_senior_v1. Luckily it can be downloaded from the snap camera assets so I did it and copied it to the PrecachedAssets.bundle folder. After this snap camera recognized the missing asset and from that no error comes up. In snap camera app the lens looks like to load correctly, the two camera feeds shows up, the loading signal stops but the aged results is not coming up . thanks, gabona |

I'm confused is the patch supposed to allow users to use the search bar in Snap Camera to paste URL links to the lens they want to use? Because mine is definitely not doing that. |

Not sure if this is because it's incompatible or something else, but has anyone been able to use "locked" filters? In particular, this lens: On Snap Camera, it loads up the base lens fine (a potato), but then shows a bunch of other alternatives all locked with "Unlock for xxx" - seems to be some sort of in-app currency??? Those locked lenses do load fine, but are blurred so you can't see your face. Is there a workaround to unblur or unlock those additional lenses? Appreciate any help! @ptrumpis |

List of Lenses that are known to be incompatible with the latest Snap Camera application.
Some lenses (infinite loading bug) can be fixed with an unofficial update and additional assets.
See here: Unofficial Update | Snap Camera Assets
Other lenses need to have their "Fallback Mode" patched.
You can apply the fix with this tool: Snap Lens Tool.
Snap lenses with missing assets:
These lenses need to have their "Fallback Mode" patched with Snap Lens Tool.
Snap lenses that require further patching:
This list will be expanded in the future with your help.
