minimap problem

Hello,

I'm trying to create a minimap for my game: I added a second camera, witch is following the player, I created a GUI with a rendering texture, I added the texture to the second camera's Target Texture, so far so good... the shapes and trees appear on the GUI but the terrain is transparent.... can you give me some ideas about this problem ?

most planes or terrains have only side or 1 face so if you turn the terrain or plane it would be invisible so I recommend you to check if the problem is that the plane is in the other side and if don't I recommend you to better use a cube and convert that into a plane if is what you mean :P

I don't know what you mean with "the plane is in the other side", can you be more specific ? Thanks.... And sorry I'm new with unity...

nobody can help me with an answer ? I searched all over to find a solution, but nothing...
