After I disable Fallback Mode with Snap Lens Tool, how do I use the .lns generated?

[alexirUDC]

I'm so sorry for asking this, I'm probably not understanding it cause my bad English. But I'm trying to use new lenses (public or created by me) and I'm not being abe to use them. I've found I need to use this other tool, but I'm not understanding how to proceed after creating the new .lns archive usying the "disable fallback mode" option

This Video is a little outdated but might help.

Short Version

1. Copy the patched file to your server /import folder (.lns or .zip format supported)
2. You need to login to Adminer: http://studio-app.snapchat.com:8080 (user: root | pass: 123456)
3. Use the search functionality of Adminer to find your lens. Each lens has two entries, one inside the lenses table and another one inside the unlocks table. You need to find the entry inside the unlocks table by searching for the lens ID.
4. Use Adminer to update the lens_url (unlock table) and make it point to your patched file in the /import folder
5. Everything inside your /import folder will be available under: http://studio-app.snapchat.com/import/

Thank you for the fast answer. I still have some doubts:

• Do I add teh patched file as .ñns format? (I see the other things of that folder are folders for each lens)
• On Adminer, what column is lens_url? I see a colum called snapcode and other called deeplink, is it one of these?
• And finally, how can I select all the non favourite lenses from the database for removing them?

Seriosly, thank you soo much, lenses are an important part of my streams

You place the patched lens file as .lns or as .zip file inside the /import folder.

There are 2 tables lenses and unlocks, snapcode and deeplink are inside lenses.
You need to use the matching entry inside the unlocks table, and modify lens_url.
You can find the matching entry with the lens ID.

Favourites are an offline mechanism by the client application.
They are not marked inside your database, but inside your settings.json file.

I'll write it down as feature request, for future versions.

Thank you. I think I did all the steps correctly, but I think this lenms isn just uncompatible. I see this log after updating lens link:

The lens has an unknown blend mode.
This can be manually fixed inside the file _scene_scn.xml created by the lens tool.
Automatically fixing the blend mode is already in planning.

I can fix this for you if you want, just attach the lens as zip file.

Oh, no, thank you so much , but it's not neeccesary.
The important thing for me was knowing if I was doing it correctly or missing some step, but I can survive without that random lens haha, don't take the effort.
