Ok so I wanted t modificate eye texture of some model, I wrote down material name in label and it turned out to be missing textures, there was not a singe spelling mistake in material's name, I tried to use different material form SAME model and all of them worked just fine and yet only eye textures were not woking, It did work in Submaterial tool but not with this one.

It's happening with team fortess 2 nad half life 2 models as well, eye materials are always pink and black squares,

does anyone have same problem?
