For now from 1.9 to 1.12.2 (in the future it will be updated to 1.15 !!!)
This resource pack will allow you to convert pixelated minecraft textures to much more realistic ones. You can make your game look very realistic without the need for ray tracing or a super powerful PC !!!
If you are interested you can download it on this page, but I recommend going to discord since there I will upload updates before planetminecraft. At the same time, you can ask for help in the event of a problem, and see the installation instructions.
