I've recently modeled my character inside Maya; here's an image. The first thing I noticed whilst creating my model is that the models could be seen through source 1, after doing a little research people stated that it was a graphical bug in Maya. However, once imported into Unity the same effect occurs.
Therefore, my Question is: How can I fix this inside Maya or Unity?
To prove that my UV map doesn't contain a low opacity texture see the second image below:
