Land LOD Trouble

[Euripedus]

I have a problem with LOD land showing up in a cell on the edge of
water. I realise I can use the console cmd "tll" and it goes away
(although everything gets a higher HDR value too, making it all look
unreal), but that doesn't fix my problem really. I need to know how to
find and exterminate rouge LODs showing up in a mod.

 

here are the screen shots, first with land LODs on then off:

The cell in which this is occcuring does not show anything out of the
ordinary in CS, so I'm at a loss as how to proceed. I have replaced the
Oblivion.esm with a vanilla one, activated only the mod in question,
loaded the game without OBSE, etc. Nothing seems to fix this glitch. Any
ideas?

Though I do not play Oblivion - own it, don't play it - I have a lot of knowledge with LOD, when it comes to Fallout. The mod in question must be changing the landscape in that area, and drastically enough to allow the LOD mesh to appear. The LOD mesh is rendered underneath the Landscape, and when you modify a landscape too much, you'll get this. The only course of action is to regenerate the LOD for the worldspace, and that is not a simple, quick task. It takes my computer on the highest detail possible for a 64x64 cell grid worldspace 24 nonstop hours to generate new terrian meshes. I can only assume Oblivion is the same size if not larger.

Basically some mod has modified the landscape without supplying a modified LOD mesh. If you can identify which mod it is, we might be able to figure out what can be done about it.

Only when the Valenwood Unleashed mod is running, alone do I get this. If I can't fix it then I will need to abandon all my previous work on this mod to my backup point and rehash the last few weeks of labor. It only happens in this cell, in this mod, because of something I did. I've tried regenerating LOD (Upadate LOD function) but not for the whole world space. The problem is that this city exsists in Tamriel, not it's own worldspace. Yet. Hmmm...maybe now is the time to move all this.

 

If you have ever used Valenwood Unleashed you know what a pain this is going to be. Valenburg is a BIG town that really needs to be in it's own worldspace. Galejro created this mod, which I rather enjoy, the new furniture, clothing and weapons are great and can be fun. But the town of Fithren was messed up. There were no bridges across the Putrid River. NPCs got trapped in Valenwood. all kinds of little irritating things that needed fixing. I'm an old Lightwave modeler and I'm starting to get into Blender, NifSkope and of courwse the CS for modding. I like to play Oblivion...problem is it's usually for 5 minutes at a time until I find a bug, a glitch, a problem...then it's off to Editland for repairs before I can get back to Testing/Playing. lol ah....what a life.

It depends how you're installing and uninstalling the mod.

 

The esp determines the short range landscape changes of course. In theory, the mod that changes the land only needs to supply one mesh in the meshes/landscape/lod folder. Wrye Bash and NMM should be removing that mesh when you uninstall the mod.

 

As or returning to editland every 5 minutes... welcome to modding!

[Euripedus]

So far i don't use WryeBash or NMM. I'm old school, do things manually cuz too much...uh...stuff can glog the works. Today I copied all the LOD files from a virgin backup. Still no dice. Installed a virgin copy of the mod including all textures, meshes, etc. Nothing. So, I'm getting used to having the distant land turned off.

 

 

We now return you to your previously scheduled editing....grrrr

[Lanceor]

Try renaming the entire meshes/landscape/lod folder so that no LOD meshes are used. Unless I'm mistaken there's already a copy of the landscape in Oblivion - Meshes.bsa so anything in the loose folders should be mod added.

 

If this fixes the problem and you want to surgically remove just the problem bit, look for the lod meshes that begin with a "60".

 

If renaming the lod folder doesn't fix it, then you have to generate a new lod mesh for that particular quad as the vanilla lod mesh sits higher than the modified land.

[Euripedus]

Thanks for the info but no, didn't work. lol but the game DID regenerate all new landscapes, bogged down the load screen. So yes you were right, there is a copy in the bsa and it hasn't been modified yet. Seems there is an lod under the mod mesh but it's real close to the height of the mod mesh at one point, the spot I assume was Galejro's start of the mod. -49,-23 thru -25 seem to be the bad cells. all the rest are WAY under the mod mesh height and therefore don't show thru.

 

Ok, about quad regeneration. I tried it once on a single cell and I got some black and purpleish coloring on the mod mesh (or a blending of the two meshes?) Not sure why the texture didn't render.

 

Thanks again for all your help. Any more advice is greatly appreciated. But don't let me distract you from your 5 minutes of game time...I mean testing. lol

 

update

 

Ok regenerated the quad for one of the cells (these are in the Tamriel worldspace...grrrr. I know why he did it this way, he built a baloon airship, was going to have it fly around Tamriel) and got the same black texture, but the land was still visible above the mod mesh. So I deleted the textures that start with 60 and viola`! the texture was back. None of this solved the problem tho. Oddly the LOD distant land only peaks out in that one cell, the one with the most drastic elevation change (for the waterfall).

Oh holy crap! I don't know what I did or what happened but now the mod crashes CS and game. I uninstalled and reinstalled the vanilla/virgin mod and it still crashes both programs. My backup too. um...unless anyone has an idea, I'm looking at reinstalling everything from scratch. And yes I have anti-virus software.

 

GAWD I hate the CS! How the *&%^$ did Bethesda ever release TES4 using that PoS?

LOL OMG! The Bethesda team is so lame sometimes. And I did a stupid thing...

 

I tried to "fix" the priorydoor01.nif so the CS wouldn't freak out every time because there is a light inside the mesh. WRONG THING to do! Made the game crash every time I got near the bloody door (same cell quad). Glad I had BSA commander! So back to modding. Still got that LOD problem tho.
