I think this analysis is partially incorrect. Being aware that there are several versions of sbluepalacegate*.nif, I have applied the following mesh mask rule:

LODGen153=sbluepalacegate,Full,Full,None,None,FarLOD,Unchanged,0,

which produces the above result.

It is correct. The screenshotted reference xx00C938 using Meshes\jk's blue palace\sbluepalacegate.nif also has Meshes\jk's blue palace\sbluepalacegate.nif in the BTO because of that mesh mask rule. The full model gate can be seen in the BTO. That reference is not involved in the issue you are seeing. As I suspected, I found the different reference to be xx5A004B in BluePalaceTerrace.esp. That is the one that is being replaced to a completely different model because of sos_seasons_vigilant_win.ini defines that swap.

You can look up these references (BA00C938 and 325A004B) in the export file LODGen_SSE_Export_Tamriel_WIN.txt to see which reference uses which LOD model in the BTO in the end.

The issue anyway seems to happen for all instances of SCWgateWinter/SBluePalaceGateWinter (the JK's Blue Palace version works just fine now when I look at it carefully). I think you might be at something, though. If DynDOLOD loads form swaps by plugin order, you are doing it wrong. Seasons of Skyrim applies rules in the alphabetical order of the config files, which is written clearly in the documentation (but I don't know what that means in this case, given the underscore - ask powerofthree). Normally, there should not be any problem applying two different rules for the same object (I have good reasons for doing so here), because it is anyway the one that loads last that wins. But if you are not using the same file order, I guess that could cause problems when mesh mask rules are involved. I could try commenting out one of the form swaps and see if it helps, but you need to fix this too.

I got confused with Base Object Swapper. Seasons INIs can have any file name and DynDOLOD does load them alphabetically (can be checked in the debug log). So "zzzConfig wins over aaaConfig". The problem is that SOS treats the filenames case sensitive while xEdit - like Windows - by default does not. For example, a is loaded after B by SOS. I will address that in the next alpha (including making sure the underscore sorts the same way - its after uppercase but before lowercase usually)

Hopefully this has not been asked already.

Is there a way to disable rim lighting and soft lighting when generating object LOD?

By default, LOD assets and thus their LOD shapes in BTOs do not set these shader flags or have a third texture.

Only LOD assets that specifically instruct DynDOLOD to keep those settings have them generated in the BTO.

I get these shader flags on the object LOD that causes trees and objects to illuminate even without the sun hitting them.

You can see here the sun is behind the mountain and the LOD objects are bright:

Once the objects themselves are loaded in:

(I froze in game time during this)

Here are the tree objects themselves:

The BTO file itself does not have the soft lighting and rim lighting on these specific trees, but sometimes they do. Even in this specific tree.

3D LOD files (overwrite with the 3d LOD resource files on the mod page)

I did not mess with the shader flags on my custom 3d LOD.

 

This is an example of a couple of trees showing the issue. This happens with all LOD objects, even mountains.

I should mention I use this mod as well: https://www.nexusmods.com/skyrimspecialedition/mods/63725

The link to the 3D LOD files requires a login, so I can not download it.

Based on the screenshots I would assume this has to do with LOD by default not receiving/casting shadows.

https://dyndolod.info/How-LOD-Works
LOD does not cast or receive shadows. This can be mitigated by the ENB distant shadow effect or Screen-Space Shadows. If large reference bugs workarounds are used, tree full models can be made to also load outside the active cells, to push their swap distance further away.

https://dyndolod.info/Help/Terrain-Underside#Troubleshooting

0005C06E uses s3dtrees_treepineforestsnow05_lod_0.nif with CRC32 91829509 which I could not match to any file I currently have. I assume it might be one from the upload that I can not access. If the LOD model sets those flags or third texture and they somehow end up in the BTO with those features despite no passthru in filename (or shapename), remove them form the LOD asset. https://dyndolod.info/Help/3D-Tree-LOD-Model

0005C06F uses s3dtrees_treepineforestsnow04_lod_0.nif with CRC32 56F8528E which indicates it is still the LOD files included in Skyrim3DTrees and Plants 3dLOD Resources, which does not set any rim or soft lighting or third texture. Its combined shapes in the BTO should not have such settings either.

The screenshot of NifSkope shows no rim or soft lighting flags being set. What is it supposed to show?

You should be able to download it now.

I am showing that the model and nifskope does not show a soft lighting or a rim lighting shader flag, yet it still behaves in game like there is one.

I do not need LOD objects to receive or cast shadows to fix the LOD issue. Soft lighting and rim lighting with the skyrim engine will illuminate the object with or without shadows casting on the object or receiving shadows. You can see here that part of the LOD object does not behave this way:

Opening the BTO file in NifSkope, you can see the shader flags between the two parts of the object LOD tree is not much different. One had a vertex color shader flag and the other is marked as double sided.

I am not sure why the part with the double sided flag acts like there is a soft lighting flag/ rim lighting.

LOD items in the further regions where the tree LOD is not 3d do have the soft lighting/rim lighting shader flag:

Some objects are illuminated the same way with or without the shader flag:

I'n not really sure what is going on.

However unlikely that seems to be, if we assume for a minute that to be true, what do you want the tool creating the BTOs to do differently if the engine does whatever it does regardless of settings? That would be something that needs to be addressed in the engine/shaders with ENB or Communuty Shaders etc.

If using ENB distant shadows or Community Shaders does not help, then I suggest to look into the normal vectors next. In these 3D tree LOD assets the normal vectors typically point upwards instead of the usual perpendiular direction from the surface. That is usually a better option for double sided triangles, so both sides are illuminated equally and brightest when the sun shines from above. Double check the BTOs that the normal vectors for the crowns still point upwards.

NifSkope shows the normal vectors if you unfold the Vertex Data array in the BSTriShape and highlight the normal entry in an array entry.

That screenshot is a good example for how the object LOD for some stony structures is not recieving shadows, while some full models that happen to be large references in the LOD area still do.

I just noticed the models in the screenshots receiving shadows are the full models. I just checked it looks like the terrain LOD and object LOD does not take any shadow at all.

In the screenshots comparing the 3d tree LOD brightness between the leaves vs the wood, it just looks like the LOD models have light shining on both sides of the double sided mesh that has the leaves regardless of where the sun is directing.

It seems like every double sided mesh does this. I wonder if there could be a solution for this.

As I mentioned, the 3D LOD assets point the normal vector upwards so that double side triangles have equal brightness on either side and are brightest if the light shines from the top (they are actually slightly angled, so not exactly)

You could test removing the double sided flag and right click a BSTriShape, Mesh, Face normals, then again right click a BSTriShape, Mesh, Update Tangent Space.

If those work better, to restore the now missing "back triangles", convert the meshes to Skyrim (NiTriShapes) format with CAO. Duplicate the crown shape with right click on the NiTriShape, Block, Copy and right click on the root 0 BSFadeNode, Block, Paste. Then right click the NiTriShape, Mesh, Flip faces, Flip normals, Update Tangent Space.

Hey sheson,
I'm crashing in cities (only Riften and Whiterun tested) with DynDOLOD A-170 generated output. I've tried disabling the DynDOLOD Output which got rid of the issue and I rolled back to A-169, generated a new output and had no issue. Crash Logs are included in Logs.zip, DynDOLOD_SSE_Debug (https://mega.nz/file/UacwCRLb#BzV3vb1x-dauLDoHt4rHjQOrNXzYHn8fS2_bk4s-4To) as always had been to large.

Could you have a look? Thanks!

Thanks for the instructions I will try this out with all the LOD meshes and see if it works.

If you are absolutely sure that the load order did not change after generating the output with alpha 170 let me know for follow up questions/troubleshooting..

Otherwise, generate a LOD patch from scratch with the latest alpha for the current load order, to verify that the crash still happens.
If it does, upload new DynDOLOD log and debug log and new crash log and keep the output around for follow up questions/troubleshooting.

Do the settings used while generating a grass precache affect the performance of grass LOD? Or is LOD grass performance solely a matter of the Texgen and Dyndolod settings? I'm a bit confused as to whether the grass precache that is generated via the MO2 plugin is actually affecting the grass LOD density or other performance variables or if that is solely determined after the fact with the billboard and LOD settings. I used No grass in objects with grass helper NG to generate the precache but I'm not sure if the grass INI settings are influencing the quality of precache generation or if they only affect full grass appearance in the loaded cell.

https://dyndolod.info/Help/Grass-LOD
The grass cache contains grass model and placement information.

https://dyndolod.info/Help/Grass-LOD#Settings
In case the grass pre-cache was generated with SuperDenseGrass/Super-dense-grass = True, expect really long object LOD generation times. Lower the density to 33% or less.

https://dyndolod.info/Help/Grass-LOD#Performance

There are settings that change the amount of full grasses and the density of full grass in the cache. There more full grass, the more LOD grass, the higher the performance requirement. The denser the placements, the denser the grass LOD, the higher the performance requirements.
