This resource pack requires OptiFine.
As you might have read from the RizCraft page, RizCraft attempts to (but is not limited by) capture the vanilla minecraft feel. There is no better way to do that than with the Faithful 32x texture pack, which doubles the resolutions of the vanilla minecraft textures. Aside from that, we have used Armour, Weapon, Horse Armour and Sun/Moon models and textures from the John Smith texture pack to achieve more of an RPG aesthetic for the combat items and environment. The Bushy Leaves and Less Obtrusive Shield add-ons from the Faithful Team flesh out the floral and provide a small quality of life change to the big, clunky shields in vanilla MineCraft (since RizCraft will add 3 more shields). This is a small yet effective package that is an amazing step up from the vanilla resource pack, but I shouldnt have to tell anyone about the gorgeousness of the Faithful texture pack.
If you are using this resource pack with RizCraft or 1.16.1+, the MC client will say it was made for a newer version of minecraft and may not work correctly. This is a bug. Ignore this message.
