Skybox - Only Color Showing

[Plazmater]

So , as title says , i have little problem.
i copied AAMFP Texture assets and named it Texture2 and place it into Redist file.
I works and i can find in editor those nice night skyboxes from AAMFP but problem start here.
When i choose what skybox i want and set it to active , in test it doesnt work only color is visible (color what can you choose under Active section.
In level editor it is nicely visible but in game when i test my custom story there is only that color and no skybox even when it is active:

I have tried to look everywhere for this problem , and i couldn´t.
I want this problem to be solved because i have this problem so long that it is annoying me.
