Do you have the Official HD Texture pack and if so, did you set it up to run through your config and deactivate the plugin? If you didn't set it up to run that way, it's overriding your textures.
Also, SMIM uses specific textures that can't be overridden by textures designed for vanilla meshes (they have different UV maps). You're stuck using the textures the author provides with SMIM unless you can find other texture packs specifically designed for it.
Thanks for the reply. Yup, I deleted the (2) esps from the official HD packs and have the "archives" section of my INIs set up to refer to the texture packs as laid out in STEP. I don't have SMIM activated right now - when I reactivated all the textures I purposely didn't activate SMIM to replicate exactly what I did the first time when everything was working.
I noticed that my Skyrim_default INI didn't have the same settings as my INI in mydocuments/mygames..etc... so I cut & pasted to make them identical. But no change.
I also noticed the following message in my INIs: SGeneralMasterMismatchWarning=One or more plugins could not find the correct versions of the master files they depend on. Errors may occur during load or game play. Check the "Warnings.txt" file for more information. But I can't find "Warnings.txt." anywhere. (Though I don't think that would affect all my textures anyways.)
Looking at the folder structure in steamapps/common....skyrim/textures... etc. everything looks good, like the textures all got installed into the right place. Which is why I thought it must be an archive invalidation or texture size thing. (edit: actually, more a texture size thing b/c with an archive invalidation problem the game wouldn't even look outside its own bsa I think)
edit: I reinstalled NMM (rolled back to the version I had when all was fine) with no diff. Just to make sure my eyes weren't playing tricks on me I deactivated all gazillion mods in NMM and went in-game. The only thing I noticed was that a workbench was slightly uglier (perhaps from just disabling the official HD esps?) but 99% of the game was low-rez soup (ie just the same as when the umpteen texture mods were "active".) I'm really stumped. Of course, just when I was running around to check various texties, a freakin' dragon shows up - NOT NOW DAMMIT I'M TROUBLESHOOTING (it didn't listen). Fast travelled somewhere else: another freakin' dragon! Aaaaarrrrggggh
edit2: since it seems like there's just something not allowing textures to go over 512, I was suspicious that in the "rendererinfo" txt file I found this line: maxPS20ins: 512. I have no idea what that even means, other than I noticed the "512" thing. And it's just a text file after all. I can't find an equivalent line in any INI file.
