Thanks guys!
I was able to fix it and it was the lighting. However I came across another issue.
The model that I am using has a very high count of polys. So I started to lower the number of polys by using (edge mode, pick an edge, loop, ctrl+backspace) method to remove the edges without making any holes and missing polys.
However, this is the problem, after awhile, the model itself starts to become distorted with black holes and missing polys when I render it but there rent any missing polys and such.
Any suggestions?
Thanks!
