Why are my imported models materials rendering with transparent holes?

So I imported a character model that had been made and rigged. But as soon as its textures and materials were applied it went pretty funky and has patches on the model that are transparent. and the actual material file doesn’t have those patches missing. Just wondering may know what the problem might be.

here, I have provided a link to an image of what I am getting to help explain what is meant.

Thanks in advanced. :slight_smile:
