Why inner content of the mesh is visible?

The inner content of my mesh is showing in the Viewport…
How to fix this??

Flip the vertex normals in Blender/Max/whatever and re-import the mesh. In Blender/Max/whatever set backface culling to be true to spot meshes like this.

Thanks for the quick reply…
Trying to Reverse the Polygon Normals in Maya and try again…
Will post the updates

I tried with reversing the mesh, but that made the back side disappear…
Realizing that it is “Lighting Issue”, I enabled the “2-sided lighting” for the mesh and it fixed the issue…

Thanks for helping me in fixing it.
