So I load up the game this morning, and suddenly find that a number of textures around Whiterun are missing, leaving only the ugly purple shade on the object. Specifically the textures for many, but not all, of the wood fences and railings as well as the chains on the drawbridge. I've tried verifying my game cache and unchecking all mods right back to the base Skyrim.esm, and they're still missing. It's quite bizarre because they were there the last time I played a few days ago, and now they're suddenly gone. The game is up to date at 1.4.27 as well as my ATI drivers at 12.2, which were updated a few weeks ago with no problems until now.

Any ideas?

Like everyone using ATI 12.2 drivers, unless you are using the absolutely latest graphics card, these threads have been advising to roll back to the 12.1 driver. that should cure your problem.

Didn't work. Reinstalled 12.1, but still missing the textures.

It looks like it's a problem with the current version of the Static Mesh Improvement Mod.
