Any idea what happened to my renderer?

My models were fine, but now they've got this weird coloration on them. Doesn't matter if they're textured or not.

I feel like I hit some key combination or something and flipped a switch. Any ideas? Restarting Unity didn't do anything, and it's apparently past my undo history.

I used to get this in Mudbox, and I had to add polygons.... I don't know why or anything, but maybe subdivide it once, and it might be better?

Other than that, the normals might be flipped, but it'd be invisible then.

Does it look weird in the actual Scene? That looks like the "thumbnail" view.

Hope this helps.
