Do I need to rescale all skybox textures?

[Klowwd]

I'm changing a valve map to nighttime mode and I was wondering if I needed to rescale the skybox textures to be the same size. If so, is there an easier way to do it rather than selecting every texture and manually doing it?

The same size as what?

Not sure at all what you mean, but the texture scale of the skybox brushes doesn't affect the skybox ingame. Upscaling them simply makes the hammer 3d view less visually noisy.
