It's a new worldspace added by Mannimarco: Resurrection. I don't know how to use settings file, there's nothing except the exe itself, a web shorcut and the readme in the zip file I've downloaded. How can I make an exception list?
Btw, after I ran TESLODGen, the mountain on which the Frostcrag Spire is built has lost its shape, and now http://img703.imageshack.us/img703/2923/screenshot2aq.jpg. It had a perfect shape before, and unfortunately I forgot to back-up my DistantLod folder before I ran TESLODGen. Is there anything I can do now to correct the mountain's shape?
So it's an injected worldspace record from another mod, not a vanilla one. That explains why Elminster and I didn't have that problem.
In the opening post for this thread it states:
Advanced Usage
==============
It is possible to control the processing for each worldspace by creating a plugins.tes4lodgensettings file in the same folder as plugins.txt.
>>>> Example >>>>
;Supported Rules: Skip, Clear, Replace
[Default]
Rule=Replace
[Worldspace]
Toddland=Clear
ToddTestLand2=Skip
<<<<<<<<<<<<<<<<<
Any worldspace which is not specifically listed will have the Default Rule applied.
With the current version of TES4LODGen, you need to add these settings into "plugins.tes4viewsettings" rather than "plugins.tes4lodgensettings". You do need to find this file first however, and the location differs depending upon which version of Windows you're using (it goes into the same folder Oblivion places some other settings files, but it's in a location not typically accessed by you, the PC user). If you have Win XP, it's probably somewhere within "C:\Documents & Settings\" so search for it.
Meanwhile, with regards Frostcrag, TES4LODGen doesn't make any changes to land height, whether near land or LOD land. So there are three possible causes that I can think of:
1 ) You've installed a mod recently which had an LOD land mesh covering that area, and the shape of that mesh does not match the shape of the mountain accurately
2 ) You've installed a mod recently which edits Frostcrag Spire, and this has repositioned the tower so that when viewed from afar it no longer appears to be touching the mountainside
3 ) TES4LODGen got the height placement wrong
Your wording implies that the mountain shape itself has changed, which rules out causes 2 and 3.
