This modpack necessarily needs optifine:

https://optifine.net/adloadx?f=OptiFine_1.16.5_HD_U_G8.jar

This time I just focused on the look of the game, having its foliage improved by Better Foliage, better biomes with Biomes o' Plenty and also a vast amount of animals with Alex's Animals. There are a lot of heavy mods here, so I advise having a good graphics card, but the modpack also has full shader support!
