In CK I accidently pressed a key, dunno which one, just before I saved and exited. Now in CK "ShipLarge01Anim" looks like this https://skydrive.live.com/?cid=b60c11d037429d8e#cid=B60C11D037429D8E&id=B60C11D037429D8E%2130642&v=3

What did I do? Even in the preview it looks like it has been wrecked. Thankfully in game all seems well.

Advice appreciated.

Looks like it's lost one of it's textures.

Can't think of anything that you might have pressed, only thing you could try looking through this and see if anything could be the culprit:- http://www.creationkit.com/Creation_Kit_Keyboard_Mapping
