the skybox isn't showin up correctly

sorry guys this my third thread today!!! but evry time i try to make a something alot of problemes show up!!!

this time when i press “p” a strange plane show up between the camera and the skybox!!
here is the .blend (yeah im using social fps tempelate cause im still a newbie lol)

good night evryone it was a long day blending and playing assasin’s creed!!

probably it’s a “camera clipping” problem?!
Select the camera, in the Camera Panel set the “Clipping End:” value for a value that let’s you see the whole skybox ( 2000 ?).

Yep, the camera clipping is too short. I made it at 128 and that worked ok.

Good luck
