Meaning of an error message of the compiler in Hammer Editor

[Sonitrok]

Hello everyone, does anyone knows what means this error message ?

"
*** Error: Skybox vtf files for skybox/sky_nightfall_01 weren't compiled with the same size texture and/or same flags!
Can't load skybox file skybox/sky_nightfall_01 to build the default cubemap!
"

How to fix it ? (my entire log is fine, i was just wondering what to do with this specific error)

It seems he can't find the file of my skybox, am i on the right track ? ^^'

Not quite! You can safely ignore this error. Because of the way skyboxes in TF2 are generally made (1:2 aspect ratio on the sides, 1:1 on the top and bottom) the engine can't use them to make default cubemaps, which are square image files used to simulate reflections. You can generate your own more accurate cubemaps manually, so there's no need to worry.
