SPECTRUM COLLECTION - FIX
Added 2022-06-25 18:54:49 +0000 UTCAs you've probably seen from my latest post about this topic, the new Sims 4 update broke the Spectrum Collection (and any color slider enabled CC).
It took a while (and a lot of work & patience) but there's finally a batch fix for it!
I'll be providing an all-in-one download for Patrons, with all the fixed Spectrum Hairs/Clothing in the next post! (Also, all Patreon posts have been updated with the fixed version, so feel free to download individually if you prefer)
Below I'll show you how to fix it yourself with the program:
You'll need to download the "TS4AlphaConverter" by CmarNYC, you can download it HERE, on the Files tab> "TS4AlphaConverter_x_x_x_x.zip" and extract the folder.
Once you have that, you open the "TS4AlphaConverter" application and this window will open:

What I did was create two folders in my mods folder: a "Spectrum" folder, where I put all my non working Spectrum CC and a "SpectrumFixed" where all the fixed Spectrum CC will go to! On the "1" you select your "Spectrum" folder and on the "2" you select your "SpectrumFixed" folder!
Make sure all settings are the same like the picture, especially the "Don't change package names" and hit "Go". Keep in mind this process might be a bit long, for me (with 157 files) it took about 2 hours... also the program is a bit intensive, so I advise you not touching anything while it works!
Once it's done, you should have your "SpectrumFixed" folder full of working content, you can now delete the content inside the "Spectrum" folder (so there's no duplicates), and voilà, everything is working again!
Make sure you've also updated the "Color Sliders Mod" by Thepancake1 to the latest version, so it makes sliders work correctly again!
