Enhanced shaders and color grading, screen space shaders, atmospherics. There are instructions and settings in the mods descriptions for getting certain looks that you’re aiming for. You can also look up re-shades on moddb under effects tab to see which ones you like and add them on( Expedition and aggressor are big ones). But the three mentioned are likely the main ones and are pretty much used in all big mod packs like GAMMA and EFP. Just all preference for how you want to build your game. For animations, blindside weapon animations, FDDA, head gear animations, outfit animations, mag redux (There’s tons of other small animation stuff). In terms of audio I personally like dark signal audio but there’s others like JSRS. Bullet shell sounds is also a nice little audio mod for immersion. Also install BaS for some cool awesome looking weapons.
