To make sure that textures don’t remain the same all the time, simulators Prepar 3D  and FSX can use 10 different texture sets Extract 10-day set archive and move them to the simulator’s installation directory.

You can use these sets in the P3D v4 simulator (64bit), but the textures were made earlier for FSX and P3D 32bit  and can look light.

Now “yesterday” and “today” will not be the same. Same works for “today” and “tomorrow”.
