the screem became brown in the first person view and black on thrid person view. I press the esc button to the menu and i came back. the camera was normal and towards to the backing view. When i move the camera to face the forward view the camera move to underground. I tried to press the f4 button and the camera became normal. Before doing this I cold do all the ajustments without a problem.
