[GT][CL][GF][HSY][CSK][MCK] All Shiny CAS items lost shine on low settings

After more testing it only happens with low lightng settings. Medium and above fixes it

Product: The Sims 4
Platform:PC
Which language are you playing the game in? English
How often does the bug occur? Every time (100%)
What is your current game version number? 1.104.58.1030
What expansions, game packs, and stuff packs do you have installed? All Expansion Packs; all Game Packs; and all Stuff Packs; Castle Estate, Modern Luxe, Poolside Splash, Book Nook, Grunge Revival, Basement Treasures, Greenhouse Haven, Simtimates Collection, Pastel Pop, Desert Luxe, Moonlight Chic, Decor to the Max, Carnival Streetwear, Modern Menswear, Courtyard Oasis, Incheon Arrivals, Industrial Loft, Fashion Street, Throwback Fit, and Country Kitchen kits
Steps: How can we find the bug ourselves? By using any CAS asset that has a shiny, metallic, shimmery, or reflective texture. I see this on both makeup and clothing items. I've had this glitch for a very long time but did not have this issue for a few months after installing the game on a new computer until it happened again sometime after I installed High School Years and not due to downloading an update to the game or the EA App.
What happens when the bug occurs? In CAS I use items or makeup that should be shiny or reflective, etc but they appear with a non-shiny texture. This also persists in Live Mode.
What do you expect to see? The CAS items to appear with their proper texture both in CAS and in Live Mode.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
Did this issue appear after a specific patch or change you made to your system? No

This is as they appear in CAS. They appear the same way in Live Mode. The lipstick example is using what is supposed to be the glossy variant as can be seen in the picture.

Here you go

I switched the setting to High and this fixed it, thank you for your help!

I'm not entirely sure when this all happened, I came back after a little break and noticed it. I can't remember when I first noticed it, but it was right before the last update, and nothing changed after the update.

I've tried with all sorts of different clothing/hairs/etc., and even on completely naked Sims, and nothing works. I've tried using different save files. I've checked Sims in my gallery who I know where wearing shiny lipstick/nails but now they're all displaying as matte. Nothing has worked so far.

Right, that would help, wouldn't it? I even fiddled with them to test it but totally forgot to post them. Here they are:

Sims: Very High

Objects: High

Lighting: Low

Reflections: Low

Visual Effects: Medium

Edge Smoothing: Low

3D Scene Resolution: High

View Distance: High

And the only checked box is "uncompressed Sim textures."

I hadn't fiddled around with it before the issue so IDK why it would've changed, but who knows. I don't fully understand how each of these settings work so it's 100% possible it's a problem on my end.
