This 1.21.1 modpack includes shaders, and a bunch of quality of life mods. It's almost entirely Client-sided, except for 6 mods (or more?) which include:
-Do a barrel roll
-Keep some inventory
-Clumps
-GUI Followers
-Replanter
-Horse buff
-And possibly Toggleable Item Frames
Some of the best mods (in my opinion) include
-The combination of Presence Footsteps and Sound physics Remastered
-Screenshot Viewer
-Sodium + Iris (Rethinking Voxel Shaders)
-Essentials (Really useful for hosting servers)
-Camera Utils
-Effective
The modpack also includes some resource packs, for example:
-Fancy beds
-Fresh animations
-Icons
-Mob Crates
-Visual enchantments
I hope you enjoy this modpack and have fun with it!
