L4D 1 and 2 missing Eye materials

Whenever I spawn any of the survivors, their eyes are always checkered with purple and black. Any links to the eye materials?

I had this problem too, but 'tis an easy fix: Open your ‘games’ menu on Steam, go to Garry’s Mod, right-click and hit ‘properties’, hit ‘set launch options’ under General, set it to -dxlevel 90. That should fix it.

thanks ill try it out.
