Thanks a lot for your reply Gen, I really appreciate it.

I've found solution to the problem, Just incase in the future someone might encounter this kind of problem.

The problem is this: I textured my character using the "Default Quality Rendering" so all the tweaking of how my character would look was based on that render set. However, the maya render is only based on the "High Quality Rendring". So, I was busy tweaking everything on the "Default Quality Rendering" while nothing was happening in the "High Quality Rendring" which the main render set considers.

After tweaking the textures on the "High Quality Rendring" it displayed exactly on the main render display.
