Chunk Animator

Chunk Animator changes how newly generated chunks appear into your game. Normally, in vanilla Minecraft, newly generated chunks just pop into existence. But with this mod installed, the chunks will have a smooth animation when loading in. The chunks will slide in from either above or below. This can be configured to your liking. However, I personally think that chunk animation looks way more better when it slides from below compared to sliding in from above. If you are using Optifine make sure the “render regions” option is disabled.
