Has anyone retextured the Tankard yet? (the cup that everyone uses in bars) I was surprised at how bad it looks, considering how often
you'll see it on your travels...even the Oblivion vanilla tankard looks better than Skyrim's. Has anyone tackled/interested in tackling it? Anything
will look better than that blurry texture.

Yes, few modders allready done that (its not so popular as landscapes)

For example > this mod have separate folder for all retextures + pictures
