Issue #195: Solitude LOD mesh problem
In Solitude, there's this house (ID seems to be 00033c34), when viewed from a distance, that has a crap mesh (seems incomplete / see through). See picture below (just a bit above and on the right of the crosshair).

Sould be one of these:
LOD\Solitude\SNineDivine_LOD.nif
LOD\Solitude\SNineDivine_LOD_2.nif
LOD\Solitude\SNineDivine_LOD.nif
LOD\Solitude\SNineDivine_LOD_2.nif

Looking at the duplicate issue (<a data-ipb='nomediaparse' href='http://www.afkmods.com/index.php?/tracdown/issue/12809-hole-in-castle-dour-lods/'>issue 12809</a>, I can confirm that there are 2 problems :
1 - the 9 divines temple : its LOD meshes are lacking the 'half-tower' (from inside the temple this is the part where all shrines are).
--> <span style="color:#ffa07a;">LOD\Solitude\SNineDivine_LOD.nif and <span style="color:#ffa07a;">LOD\Solitude\SNineDivine_LOD_2.nif. This is too sophisticated for my actual 3D modeling knowledge. I cannot work on this at this time.
<strike>2 - the giant rock under the temple : its 1st LOD mesh (<span style="color:#ffa07a;">LOD\Mountains\Unique\solituderockarch02_lod_0.nif) is undisplayed ingame because it is affected by the wrapping texture bug (see my <a data-ipb='nomediaparse' href='http://www.afkmods.com/index.php?/topic/4079-skyrim-vanilla-lod-source-files/'>tutorial</a> for explanation). Plus, this mesh uses wrong textures : <span style="color:#ffa07a;">textures\landscape\mountains\MountainSlab02.dds and its <span style="color:#ffa07a;">_n 'sister' that are 1024x1024 instead of <span style="color:#ffa07a;">textures\lod\SolitudeArch02LOD.dds and its <span style="color:#ffa07a;">_n 'sister' that are 256x256. The entire UV map also needs to be redone to fit in the texture. I'm currently working on this.</strike>
<strike>EDIT : WTF ! All <span style="color:#ffa07a;">_0 LOD meshes from <span style="color:rgb(255,160,122);">meshes\lod\mountains and <span style="color:rgb(255,160,122);">meshes\lod\mountains\unique folders are affected by this ! That would explain why many huge mountain parts 'pop' when approaching.</strike>
EDIT : I wrote wrong things. The .bto files generated for this area (<span style="color:#ffa07a;">tamriel.4.-16.24.bto, <span style="color:#ffa07a;">tamriel.8.-16.24.bto and <span style="color:#ffa07a;">tamriel.16.-16.16.bto) are perfectly 'as intended', provided the base LOD meshes available for this huge rock/mountain object. And that is the <span style="font-size:24px;">real issue : LOD meshes for this rock/mountain <span style="font-size:18px;">do not fit the full-poly one.

So, the actual issue lies in improper shape from solituderockarch02_lod_<span style="color:#ffa07a;">0/<span style="color:#ffa07a;">1/<span style="color:#ffa07a;">2.nif meshes. A huge haul of work, I can't guarantee I'll be able to do anything...

Ok, <a data-ipb='nomediaparse' href='http://host.conseiljedi.com/~nico/Skyrim/Fixs%20persos%20pour%20USKP/Partial%20Fix%20Issue%20195.7z'>here</a>'s a partial fix. This archive contains both a new mesh for <span style="color:#ffa07a;">solituderockarch02_lod_0.nif and the fitting .bto file for this area of the game. It's basically a simple copy/paste from <span style="color:#ffa07a;">meshes\landscape\unique\solituderockarch02.nif with all geometry merged into a single block and using the generic 'mountains LOD texture'. The rendering ingame is excellent (no more gaps) but rather performance-unfriendly (imo) because it's now a heavy-poly stuff (but some other LOD meshes already in the game have nearly the same amount of vertices : look at <span style="color:#ffa07a;">meshes\lod\mountains\unique\markarthcliff04_lod_0.nif for example). Proof that this mesh was the culprit is demonstrated. I'm afraid I won't be able to do much more for the rock issue.
Anyway, the 9 divines temple still lacks its back tower...

Actual progress so far :

<div>-fixed solituderockarch02_lod_0, 1 and 2.nif which didn't fit their associated full-poly models
<div>-fixed missing LOD for a castle wall in Solitude
<div>-fixed missing rear tower in sninedivine_lod.nif and sninedivine_lod_2.nif
<div>-regenerated appropriated objects LOD files (Tamriel.4.-16.24.bto, Tamriel.8.-16.24.bto, Tamriel.16.-16.16.bto)
<div>
<div>You may expect a slight performance drop due to the new stuff vertices. No noticeable difference on my rig. Tested and works fine.
