Time of Night not working properly

[Neninyan]

I think I'm having an issue with the Time of Night skybox: the entire skybox is black while i saw in some tutorials it should have a sort of blue fading. It shows stars and light source but the "sky" is pitch black and doesn't change color regardless of the settings. I thought it was a compatibility issue but it seems my software meets the requirements. Could it be a graphic card issue (GeForce 920M)?

are you loading skybox material in the material tab ? + skybox lighting ? (idk if you're new in ray-cast or not)
