Max. 2048x2048 textures.
This version is more optimized. I'd recommend downloading it over the 4K version, since it looks the same unless you zoom in very close.

Old version!
2K version.
The textures in this version are more optimally sized while being adequately detailed.

Max. 4096x4096 textures.

Old version!
4K version.
I'd generally recommend the 2K version, since it looks about the same and blends in with the rest of the game better while being more optimal for performance.

Old version! Not needed for V2.
