Most people think that the only way to find out what mods are broken/missing mesh is to go through all the hard work removing files one by one from the Mods folder!
Its hard to find out what mods are broken in CAS or in game because the CC thumbnails arent very helpful.
However there’s a much easier way if you use Sims 4 Tray importer.
This works for Objects as well as CAS items.
If you find yourself frustrated finding what the filename is of the hair that is bugging you, this is a solution.
Download Sims 4 tray importer and then make and save a sim that has all of your broken cc. So your sim will have only the mods you wish to find and delete.
Then after you have saved your sim/sims with corrupt cc on them. open tray importer and click on the saved family. then you’ll see three tabs, General|Files|CC
Obviously you want to click on the CC tab and it will show you all of the CC used in the making of those sims. Thus revealing all of the filenames of your broken CC. Making it easier to track down and delete the bad files.
This also works for builds, so if there is a bunch of furniture or decor you want to get rid of, you can make a lot with just all of that stuff in it, and save it, It’ll show you all of it. so you can delete all of that annoying stuff from your mod folder!
