I'm not sure what that mod is either, I would probably love it tho! I don't care for the painted on cartoony look of TS4, never have.
For years, I only used alpha CC hair, clothes, objects,and walls. I had default texture replacements for grass, rocks, water, trees, and streets. I also used reshade to tone down TS4's bright colors and make them a little more muted in tones because TS4 is extremely bright colored, it was just way too intense for me. I'm a neutral pallet type person in RL, never cared for bright colors at all.
Now a days, I just go with maxis match stuff if I have CC in my game. Not because I love it or prefer it, it's just less jarring when I remove my mods folder after patches and pack installations.
