AI mask functions in lightroom don't work for me

Question

Hello, I cannot use Lightroom's AI mask creation functions. When trying to use this function I get a message saying "some Ai skins need to be updated." I click update but nothing happens.

Hey Jorge,

Welcome to the Lightroom Community. We need more details to help you.

What version of Lightroom and Windows are you using?

Would you mind sharing the screenshot of the error?

These symptoms can occur when Lightroom can't write the .lrcat-data file for some reason, either because LR has corrupted it or there is a permissions issue. LR stores computed masks in that file. Try these steps:

1. In Lightroom, do Edit > Catalog Settings > General > Show. That will open Windows File Explorer on the current catalog folder.

2. Exit Lightroom.

3. Move the file <catalog>.lrcat-data to the Desktop.

4. Start Lightroom.

5. In Library, select all photos and do Photo > Develop Settings > Update AI Settings. That will recompute all the AI masks, which could take a while. But it won't update Generative Removes, so you'll have to go to each photo with Remove, click on Remove, and then Update.

Let us know how it goes.

Thanks,

Shivani
