shadows\mirror Disappeared !!!

all shadows and mirror Disappeared :S i checked every thin … theres just 1 light and it drop shadows :S… plz help !

Check to make sure the Ray button in the Scene>Render panel is enabled.

A more coherent post would help.
Are you saying the options are missing from the properties panel or have they gone from your render. Have you selected shadows in your light settings, if they are raytraced shadows have you selected enable raytracing in your render settings.?

i fixed it by appending every thing to another work :)!
