How to make my world picture more exquisite?

First of all, some high-end light and shadow can realize cirrus clouds, the roundness of the sun and the elevation of the water surface. Secondly, if you want to make the mc picture more exquisite, you can use the material package of 1024× 2048× on the current network. What is this concept? Let me give you an example. The original material of mc is 32×. Using these material packages can make mc's material close to reality, but it requires high configuration. If you are not satisfied with the terrain of mc, you can also download a smooth terrain mod and change the square of mc itself into a smoother terrain. The compatibility of the material package is unknown.
