Mesh partly shows wireframe upon texturing As you can see from the attached image, there is a problem with the texturing. I have not yet added a texture, but simply went into texture mode, and part of the mesh shows a wireframe as compared to being white like the rest of the mesh. This part is the "backside" of the cape; it doesn't show the the white color, whereas the "front-side" does. The cape is just a plane with many vertices. This also holds true for the inside of other parts of the mesh like the shirt, shorts etc. When I did add a texture image, the error still persisted. What is causing this, and how can it be resolved? 

UPDATE:
Backface culling is disabled.
I am using blender version 2.69.

Thanks in advance.
You probably have enabled Backface Culling, either in the material's settings if you are in the game engine or in the viewport's shading settings:

Game engine material settings:


Viewport shading settings:


Disable it and you should see the texture of your object on both sides.

This is not a bug in Blender but an optimization technique which is used in games to reduce the GPU load. If you have a closed mesh you can not see the backsides anyway. Only if your mesh is not closed you need to draw both sides.
