Isometric camera skybox not working.

I'm making a isometric game that takes place on an floating island. I set my isometric camera into this setting and the skybox is working properly in scene mode but won't show when its on a game mode.

when i set the near clipping planes into -50 the skybox is working but the other objects like that floating object is half body

and this happens when i change the near clipping into -51 to -1000 and so on. The floating object has full body but the skybox is not showing anymore
