Fresh Animations For Minecraft 1.19.1+Published Aug 2, 2022
Fresh Animations is a texture pack that allows mobs and animals, even villagers, to behave wildly and fluently, no more stiff animation that Mojang presented; this applies to 65% of the mobs in the game, meaning that you'll go around and see a variety of motions between a pack of animals and mobs, they will be moving their parts smoothly and entirely, and in some cases, for instance, the villagers, they will even have facial expressions depending on the situation and how they feel, if they're terrified, let's say a raid had begun or a zombie is attacking them, you'll see that their eyebrows have gone up and their eye bowls widened, same goes to pigs, but their facial expressions are way minimal comparing to the villagers' they will only wander around with their eyes.
Fresh Animations Texture Pack made Minecraft way more realistic, and the most impressive part about it is that it didn't have to adopt a ridiculously high resolution to achieve that; it only made the movements of the mobs in the g same much more dynamic and even added some behaviors to a group of animals, for example, the cats will lick their paws.
That said, you can install the Fresh Animations texture pack from the green button below, and don't worry about the performance. The Fresh animations pack doesn't feature any Pom and PBR or ray tracing nor requires even a shader to run, and you can just play it on any computer as long as it can run the Vanilla Minecraft.
