This is a request for info topic, and depending on what I get back I may release a mod of fixed models which will help get rid of a lot of texture flickering around Skyrim.

First, here's 2 images:

Basically, the problem I'm thinking of fixing is the double texture thing going on in the 'before' image. At first glance it might look like fine, but the two stone textures don't make any sense. If the light gray one was plasterwork, then maybe, but as 2 different stone wall constructions in the exact same place it doesn't add up.

That's probably a bad example in terms of the flickering thing I was talking about, but it's a symptom of the same problem - namely multiple meshes in .nif files with competing textures. Windhelm is full of them, and I'm sure other places are too.

Now, in the 'after' image you can see what it looks like after I 'fixed' it. I think it just look 'right' by comparison, flickering issues aside. The thing is that all I did was extract the .nif and remove the blocks that had the competing textures, and I'm not very familiar with working with .nifs. Here are 2 images from nifskope:

• http://skyrim.nexusmods.com/images/190646
  
• http://skyrim.nexusmods.com/images/190647

You can see that block 40 has been removed.

I'm concerned that this will cause problems. I've loaded it up in game and it worked perfectly, but I'm hoping someone with a good bit of .nif experience can tell me if this is an inherently wrong thing to do or if I'm missing something about those blocks being there in the first place. I'm presuming it's an error on Beth's part (though there seem to be so many it's kind of weird).

I'd appreciate any input from some knowledgeable folks...
