Weird Looking Character and Environment in Unity

Hello… I am new to unity
I have a problem… the problem is that when i imported any character to unity, the color of clothes and everything looks weird…
Weird kinds of line and purple patches are formed.


Original Character at mixamo

is there any transparency or alpha on the texture? almost looks as if a purple normal map is visible through alpha in the Diffuse texture. Don’t know if that is even possible but thats what it kind of looks like

It was due to my DX10 graphics card. Now working fine after upgrading it.
