Snow LOD problem in Forgotten Vale

[massiveactive]

Some snow has strange LOD in Forgotten Vale, after the two dragons broke through the lake

Better Dynamic Snow and Nordic Snow installed, other locations seems fine

Sure, here you go:

Moved to a similar thread.

The TexGen logs do not show an entire generation session. Make sure it rendered textures\dlc01\lod\DLC01IceSnow.dds.

It seems the DynDOLOD Resources for Skyrim LE contain an outdated LOD model. Replace ..\Meshes\dlc01\lod\lakesnow01_lod.nif with the one attached, then Execute LODGen for DLC01FalmerValley again in Export mode to update the object LOD meshes.

Yes that fixed it! DLC1IceSnow.dds was correctly generated as well. Only thing that is noticeable is some tiling, which turns out is due to the rendered normal map. It may be correct like this though, just not visible as much in the full model, as seen here:

 

Thanks for looking into it!

You seem to have a much bumpier textures\landscape\Snow01_n.dds normal map texture replacing the vanilla one.

Hm that is strange, apart from unofficial patches/engine fixes my game is 100% vanilla. I'll investigate further if its something on my side. 

Edit 1: textures\landscape\Snow01_n.dds is provided by vanilla BSAs.

Edit 2: Wait, in the preview, it looks perfectly normal. Just when its rendered and saved, the normal map looks that intense: 

Edit 3: Here are the TexGen logs: https://drive.google.com/file/d/1orujy8PfMtcqrZ4OtPfvoGC-_Q2G64jr/view?usp=sharing

I have the feeling all rendered textures are bumpier than they should be. They look fine in the preview, but not after they are generated and saved.

Yes, in that case it seems it is something in TexGen. The preview should match the output or vice versa. I will look into it, but might be a day or two.

Get the latest test version from https://dyndolod.info/Downloads/Test-Versions and generate new output.

The preview should match the generated texture for the same resolution. The preview typically starts at 512x512.

The problem was a mipmap issue were it might have randomly used the largest mipmap (similar to setting UseMipmaps=0 in TexGen INI) instead of filtering the appropriate mipmap levels.

Note that the snow01_n.dds in Skyrim LE has mipmap that go basically flat, so if you render smaller output resolution it will become even flatter, which should match further away full models better.

Looks perfect now, thanks for looking into this!

I assume this affected all rendered textures, also billboards for example?

Some, not sure how random. It won't be that obvious like with this particular normal map texture, though. Check its mipmaps, the 4th (64x64) is already flat.

Yea its like they faded it out for higher mip map steps to eventually make it completely flat.

If you happen to update the resources for LE because of the lakesnow01_lod.nif, maybe you could also include the fixed impextbridge01_lod.nif? It still missing the Z translation in the resources for LE.

Edit: Sorry just realized the resources weren't updated yet since I reported it. Referring to this:

The Resources are updated. The updated impextbridge01_lod.nif should be included since I wrote that in the reply which typically means I updated the source for the archive already.
