Are these the original 2x scale textures from the PSD of Nevrax artists? Or did you really lose them, and doing an AI upscale?

EDIT: Seems like AI upscale. Looks nice.

Keep in mind, for the 128x128 and 256x256 ground textures, these are actually 127x127 and 254x254 textures. For the small textures, the outer edge is repeated. For the large textures, the middle and outer lines must be repeated. The landscape tiling mechanism expects this for seamless interpolation.
