@Bluebellflora
thanks for the reply! sorry again for that long message. about my settings in-game - i've got everything set to the highest possible settings. Uncompressed sim textures is on, post processing effects are on, laptop mode off, retina display on, vertical sync on, and usually I play in fullscreen mode at the resolution setting that's around 4k (it's the first 4k listed resolution). That said, I've adjusted my graphics settings to all lower options, have adjusted the resolution settings as well, tried in windowed mode, etc.
Also - for a screenshot of the effect on an EA texture - in my first post the window I shared a picture of is an EA window.
As for the 50/50, when I first got the issue on the fridges and the three TV screens, I did a repair, folder refresh, and a full 50/50. When I had nothing in my game besides those five objects, they still appeared with the effect. And at this time, the effect had never before spread to every surface in my game. That didn't occur until later on (only change in those circumstances was progression of time).
After my uninstall/reinstall, I did a sort of backwards 50/50 again, and was pointed to the fridges and those TVs again. At that point (the date of my first post here), having those five objects in my game was causing the effect to spread to all textures in the game, including those EA windows. Once those five objects were out of my game, the effect was only visible on certain objects (the ones I listed later in my last post.
Additionally, I've identified another object that has the exact same visual effect that is seen on the two refrigerators in the image on my first post - the one with a dark and empty apartment. That same effect appeared last night on a CC sink, from that same LittleDica Modern Kitchen Pack. Only the countertop sink displayed the effect - the standalone sink looked totally fine.
About the cube map stuff you shared - that looks EXACTLY like the effect that I see on the TV screens, windows, computer screens, etc. In my game last night I even started to notice that effect, very subtly, on Peacemaker's desktop computer from the Vara Office set.
I read through the post you shared but other than recognizing the look of the cube map, I wasn't really able to understand much of what that means for this issue. If these same objects are not showing the effect in other people's games, then it can't be a matter of messed up CC can it? I've also tried redownloading all the CC in question of course, but no change.
Ugh, I really hope we can figure out what the issue here is. EA, please help!! I want my Peacemaker CC back in my game! And of course LittleDica released another CC set today, and I'm guessing that stuff would show up with glitches in my game as well. I have no clue why. I really don't understand why the effect shows up on certain pieces and not others, and then why it suddenly jumps to all other textures, CC or EA.
