Flickering maps

Our artist was experimenting with adding materials in Unity, when the models started flickering between the maps (color maps, normal maps and specular maps) as he was navigating through the scene. Does anyone have any idea how this happened?

Thanks in advance.

Also our artist wants a super shader that’ll include all sorts of maps (color maps, normal maps, specular maps, fake shadow maps in the form on Decal with 2UVs, and alpha maps). If anyone has this super shader, please share, he’d be very appreciative.

I’ve seen this too on my Windows box. I’ve not attempted to narrow it down yet, but I did notice that that the only object that is flickering is the only one using a bump-map shader on it.

The objects that flickered uses the Bump Color Specular shader from the Unity Wiki.
