NaturalRealism is a texture pack which aims to make Minecraft more realistic, by giving it a softened and refined feel. However, it manages to do this while maintaining the default 16x resolution. What this means is that you won’t be losing any frames while playing with this texture pack. Additionally, this will be perfect for those who like how the game looks by default, but would like to spice things up a bit.
NaturalRealism works with the latest version of Minecraft (1.13)!

For Minecraft 1.12/1.13
