  1. This is a beta of [FNV|FO3|FO4|FO4VR|TES5|SSE|TES5VR|ENDERAL|ENDERALSE]LODGen/Edit with terrain LOD meshes and textures generation. This is for experienced mod authors and users that know how to use xEdit, xLODGen or DynDOLOD already. Installation and Setup Download xLODGen beta 97 - based on 4.1.4c Unzip into a dedicated folder outside of any Steam, game or mod manager folders or special Windows folders like Program Files. Rename xLODGen.exe to [game mode]LODGen.exe (TES5LODGen.exe for example) or start with command line parameter -fnv, -fo3, -fo4, -fo4vr, -tes5, tes5vr, -sse, -enderal, -enderalse Use -o:"c:\OutputPath\" command line parameter to change where files are generated to, default is the game folder. Then install output as a mod. Do not generate into any game, any mod manager folders or special Windows folder like Program Files x86. Use command line arguments to set the paths to certain directories and files if required. For example: -m:"c:\Users\[USERNAME]\Documents\My Games\Skyrim Special Edition GOG\" -p:"c:\Users\[USERNAME]\AppData\Local\Skyrim Special Edition GOG\plugins.txt" -d:"c:\GOG Games\Skyrim Special Edition GOG\Data\" Requirements Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019 - Required by LODGen.exe/LODGenx64.exe and Texconv.exe/Texconvx64.exe. Get matching platform x86/x64 depending on which xLODGen.exe (x86) or xLODGenx64.exe (x64) is used. RTFM and Share Results See the included Skyrim-Occlusion-Readme.txt for a brief explanation of the Skyrim TVDT Occlusion data generation. Read the hints that are shown when the mouse pointer rests on a setting. Ask specific questions or give feedback in the dedicated Skyrim TVDT - Occlusion Data thread. See the included Terrain-LOD-Readme.txt for a brief explanation of the settings for terrain LOD generation. Read the hints that are shown when the mouse pointer rests on a setting. Ask specific questions about terrain LOD in this thread for a more in-depth explanation if required and share feedback (with screenshots) about results or problems. These tools generate LOD meshes and textures "exactly" like CK, but not like the meshes and textures which are shipping with the games (they are often manually edited). However, these tools provide more options and higher resolutions (use the x64 version if there are memory errors because you believe you require 4k or higher) and can be updated to add more useful features and options. I did some testing in the different games, but finding the best combinations of options and settings requires lots of testing and are a matter of personal opinion and which game is used, the load order, mods, even different worldspaces probably. That means, I am only able to give generic guidelines and hints to send you off to find and test for yourself and share your results. My main interested is that generations works correctly and without problems for now. Check out the thread xLODGen Terrain Settings Compare. Also refer to any modding guide which has a list of relevant mods close to your load order. The object and tree LOD generation is the same as the current versions of xEdit / xLODGen. Refer to their respective descriptions and explanations. Obviously, users of Skryim/Enderal/Skyrim SE/Skyrim VR/EnderalSE continue to use the easier and more comprehensive DynDOLOD for drastically improved object and tree LOD generation and only use xLODGen for terrain LOD (and maybe Occlusion) generation. First Time Here are suggestion to start without going crazy and that should be quick enough to generate: Set quality of meshes for LOD4 to 5 and then +5 for each next level. Or just set levels 8/16/32 to 10. Check protect cell borders (yes it fixes the ugly terrain drops at outer cell borders that still exist in Fallout 4). Use the max vertices setting only if you want to hard limit max file size. In Skyrim Special Edition or Skyrim VR, if you notice terrain briefly flickering when new areas are loading in, set [Display] bEnableLandFade=0 in Skyrim.INI Set Optimize Unseen to off for LOD4 for first generation. Start experimenting with a value of 550 with a quality setting of 10 or lower for LOD32 (used for map) and compare coastlines and file size to other settings. To quickly generate terrain LOD meshes just for the map, check only terrain LOD Meshes, check the Specific Chunk checkbox and set drop down to 32. Leave SW fields empty for complete map or set SW cell coordinates to same values as a *.btr filename to test a specific area with lots of water, river etc. Set texture sizes to 512 for a start. Larger sizes and large world spaces will take a considerable time (like 15 to 30 minutes or more easily). Each higher resolution means quadruple the work. Use DXT1 for diffuse and 565 (DXT1 if on Windows 7) for normal maps. If generating for Skyrim Special Edition and VRAM is not of concern use BC7. Uncheck mipmaps, raise steepness and Bake normal maps. For now, leave the Brightness, Contrast and Gamma at 0 and 1.0 respectively. It seems that only Skyrim CK and Skyrim SE CK are manipulating the intensity of the textures to adjust for the noise.dds and the god awful "improved" snow shader of Skyrim SE (just turn that thing off, really). If textures seem too dark in the game, brighten the noise.dds instead or vice versa. That way you can get perfectly matching LOD textures that look just like the textures in the loaded cells. For Skyrim a good average color of the noise texture seems to be around #C0. See below for a couple noise texture downloads. If you want to test larger texture sizes, use the chunk option to limit the number of textures that need to be generated. For example, check [x] Specific chunk, leave the drop down empty and set WS to the lower left cell coordinate of an 32x32 area, like 0, 0. It will then generate all textures up to 31,31. Not all worldspaces have their origin at 0,0 so you will have to check already generated meshes/texture filenames for their lower left coordinates. Questions and Feedback Obliviously anything related to terrain LOD should be posted in this thread. Posts related to Occlusion should be made here. Recommended Optionals TES5-Terrain-Tamriel.esm (Mega), SSE-Terrain-Tamriel.esm (Mega) TES5-Terrain-Tamriel-Extend.esm (Mega), SSE-Terrain-Tamriel-Extend.esm (Mega) - These extend the sea of ghost further to the north (see screenshots) SSE-Terrain-Tamriel-Full-Extend.esm (Mega) - Entire map from -96,-96 to 95,96 with northern ocean extension. Useful for mod authors. Put in game data folder obviously. Adds back terrain for Skyrim (Tamriel worldspace) at the outer edges so there is no missing terrain meshes/textures when generating terrain LOD for Skyrim. Load as early with lowest priority as possible, so that any other plugins overwriting or adding land records or cells with the same coordinates take precedence. Only required to be loaded when generating terrain LOD. No harm done when loaded in-game but typically the player can not get close to these areas. There are no effects outside the far away added cells. Noise Single color flat noise, Adjusted vanilla noise, HD Terrain Noise Texture SE Examples for Skyrim. Install to game folder like any other texture mod. The noise texture is applied in-game on top of terrain LOD textures, so no effect for LOD generation. Only the red channel is used in case the textures is not a grey channel format. MipMaps are ignored. The textures is tiled 3x3 per LOD quad, e.g. for LOD level 4, the noise texture is repeated 3 times to cover 4 cells, for LOD level 8, the noise texture is repeated 3 times to cover 8 cells and so on. Test-Terrain-Tamriel.7z For testing terrain LOD distances. Plain color terrain LOD textures for Tamriel with coordinates for every LOD quad. Green for LOD 4, yellow for LOD8, blue for LOD 16 and red for LOD 32.
  2. I know, it is probably should be in a different place, but I will post it here. So, my specs are CPU – Ryzen 7 2700X (8 cores, 16 threads), GPU – GTX 1660Super, RAM – 16 GB single-channel; I am on windows 11, and previously was on windows 10. In Windows 11 Microsoft changed power plans. Previously you needed to change it to maximum performance in control panel. But now you need to keep it balanced in control panel, and instead set it to maximum performance in settings of windows 11. Before that, it was maximum performance for me in control panel, because i didn't know that they changed something. DynDOLOD and xLodgen generating times was way longer that is should be: xLodgen around 1,5h and DynDOLOD are several hours. Yesterday i noticed that my CPU is not utilizing fully. And actually even under clocking, my CPU should run at 3.70ghz, and was running at 3.20ghz. I set to maximum performance in settings of Windows 11. And Bam! Now xLodgen times are just one hour or maybe less. And DynDOLOD is just 42 minutes with occlusion checked, all world spaces, and without grass lod. Wonderful. Sorry for not very clear and long text, but I hope it will help to someone who's getting way longer times than should.
  3. The following was preliminary testing. Read through this for general background about our testing and findings. The end result will always be what we recommend in our latest mod-build guide. As of last update to this post, this is the 2.0.0 WIP settings I am testing various xLODGen settings for "Terrain". I compare the same two areas (snow/no snow). So this is not comprehensive, but gives people some ideas of settings results (on my system) with STEP 0.3.0b. It is a relative compare of different terrain LOD results, all else remaining equal. skyrimprefs.ini LOD settings: [LOD] fLODFadeOutMultActors=15.0 fLODFadeOutMultItems=10.0 fLODFadeOutMultObjects=30.0 fLODFadeOutMultSkyCell=1.0000 [TerrainManager] bShowLODInEditor=1 fBlockLevel0Distance=50000 fBlockLevel1Distance=72500 fBlockMaximumDistance=94000 fSplitDistanceMult=4.000 fTreeLoadDistance=72500 Settings Rationale Based on my review of sheson's xLODGen thread and documentation, it looks like we should be using best quality and largest textures at LOD4, baking normals for best result (only if normals size ≥ 512 at a given level). Why? Because, in RL, resolution of our environment increases as it gets closer. Also, sheson recommends not tweaking brightness/contrast/gamma without good reason: he suggests lightening/darkening the noise map instead. I have confirmed that changing gamma between 0.97 and 1.10 has no apparent impact in game (data not shown). Lastly, raise steepness should be a good add for LOD8/16/32, since it increases bump effects for mips (probably not necessary at LOD4, due to higher quality textures, and closeness of these textures). I did compare using/not using raise steepness, and I didn't find any really noticeable difference (Lo setting does not include at LOD32, but all others do), so I am including it simply because it sounds rignt "just in case". Compression type does have a significant impact on quality, even for diffuse. BC7 is observably superior to DXT1, particularly with respect to shore-line jaggies around water. Compare order: Optimal settings (my system, my opinion) > lo settings > hi settings > ultra settings. Links to the settings are also below. My system is agnostic of these settings. I take no detectable performance hit either way, but I expect that typical PCs will see some difference of more/less significance (system specs in sig). Optimal Settings - LOD data ~ 5 GB, gen time ~ 45 min Lo Settings - LOD data ~ 2.5 GB, gen time ~ 25 min Hi Settings - LOD data ~ 9.5 GB, gen time ~ 45 min Ultra Settings - LOD data ~ 33.5 GB, gen time ~ 45 min It would be great if someone with a PC closer to that recommend for STEP and also running STEP would test xLODGen and let us know about performance impact and time to generate. UPDATE: After getting some feedback from sheson: Added Solitude (looking South from near the main gate) Increased quality on Lo settings to '10' for LOD16 and LOD32 Examined VRAM usage in all scenarios and include a compare of with/wo mipmaps in the 'optimal' settings (apparently, it's not clear if mipmaps are used at all by LOD. sheson confirms that diffuse does not use them, but normals might) Updated Lo Settings (else they are same as linked previously) Compare order: Lo > Hi > Ultra > Optimal > Optimal (without mips) Optimal Setings (no mips) Findings: FPS stats are largely unaffected by terrain LOD quality on my PC. VRAM usage was consistently lower for Lo settings relative to all others and no-mip-Optimal settings (versus Optimnal WITH mips). Not a huge diff, but lower well beyond the +/- 200 MB variation in reported VRAM usage. Optimal (no mips) was comparable to Lo in terms of performance but noticeably better in terms of quality. VRAM usage stats are not entirely reliable, because they varied by +/- 200 GB on my PC on any given save-game load once stabilized. This is consistent with how VRAM (and RAM) behave. Algorithms are being employed at any given time in any given system that govern use of RAM. It depends on what the GPU is 'thinking' at the time a save game is loaded: are you loading from a fresh game boot via MO? Did you recently reboot your PC? Are you loading one save game after another? .. it is inconsistent, but not wildly so. My findings are that VRAM usage is a bit less with Lo settings and by NOT enabling mipmaps/raise steepness. Based on the screen compares and VRAM usage, there is no reason to enable mipmaps or "Raise Steepness" on my system. Simple Summary (for my PC) Use Optimal Settings (no mips) or some proportionate deviation from that: LOD data ~ 4.2 GB, gen time ~ 36 min This takes a bit less time to generate LOD, probably decreases VRAM usage to a marginal extent, and results in quality that is all but indistinguishable from Ultra settings. DXT1 compression does not appear to save much besides disk space and costs in quality, so use it on diffuse maps ONLY if disk space is a major issue.
  4. Hi I hope you guys are ok. I am new to modding and I downloaded xLODgen to use it in skyrim se, it turns out that I rushed and ran xlodgen.exe before following the installation steps, I tried to open the game and it didn't open, then I followed the installation steps but the game still doesn't open. Is there any way to revert the changes after running the program or fix the problem to be able to open the game normally? Do you know if the mod works for Skyrim AE? Thank you...
  5. Guys, I created a Reddit and a STEP Forum account because I simply cannot find a fix. I need help really bad. I am on AE 1.6.xx Full Mod List can be provided but Issue is mostly with xLODGen application -The Issue is with SSE xLODGen 4.1.4b (Ver. 93) (Latest) -The Options menu does not appear after Background Loader is finished Instructions per STEP Guide were followed I followed and downloaded xLODGEN from: https://stepmodifications.org/forum/topic/13451-xlodgen-terrain-lod-beta-93-for-fnv-fo3-fo4-fo4vr-tes5-sse-tes5vr-enderal-enderalse/ I can include screenshots of my xLODGEN executable in MO2, Vortex and the Folders of my xLODGen application and its Output folder I set. -Image of my Executables in MO2 and Vortex: https://imgur.com/a/xnDS8qV The Issue is when I open SSELODGen, it loads all my plugins and says "Finished" but no Menu or Options Window appears. I set an Output path; my command line arguments look good. I don't know what else it possibly could be. It is not in any game folder or directory related, none of it is. I have it in its own directory away from OS and Game directories. I have the latest version of this tool. I attempted to use it today to finally build Terrain LOD for this first time on my current playthrough. I have the Terrain Tamriel ESM installed and placed near the top of my load order as well. DynDOLOD has not been run yet. Literally stuck at the first step. SEELODGen simply will not open its options menu after it is "Finished" loading files Please help, I've been a heavy mod User of the game since 2013, if any questions or troubleshooting steps need to be asked or more information is required, I can easily provide. I can post my SSELODGen Log if needed. Arguments: Target: A:\Documents\SSELODGen\xLODGen\SSELODGenx64.exe Command Line: -sse -o:"A:\Documents\SSELODGen\Output\" I have also tried, -o:"A:\Documents\SSELODGen\Output\"
  6. So after following the guide I ran over to Markarth to get a that sweet sweet free haunted house when I noticed that the rock walls around town were black from afar. As I approached them they rendered into this odd glassy low res texture. Pre-update everything was pretty much kosher. Not sure what changed but I'll try it again to see if it's on me and where I may have botched. Any help would be great. Thanks.
  7. Hi, not sure how to phrase this. I'm on Step 5 of the 3.0 guide, at the xLODGen Generation. I don't get very far before my screen freezes with square color splotches checkering it, and then my entire PC just blue screens. I'm not sure if anyone else has this issue, but I've tried to generate about 4 times and this has been the result each time. PC Specs: CPU: AMD Ryzen 3200G GPU: Gigabyte Radeon RX 580 RAM: 16GB DDR4 If I missed anything pertinent like an idiot, let me know. To preface further, I've successfully and meticulously gone through every Step 1-4, so I don't understand why this would be the one snag. I've also scoured the STEP forums and interestingly enough no one has encountered a problem similar to mine. Thank you ahead of time.
  8. Hello there, I'am modding my Skyrim SE with the Nolvus modding Guide. At the end I have to generate Occlusion with xLODGEN. I use the xLODGENx64.exe (4.1.3d). I start the application from within Mod Organizer 2.3.2 with the -sse command. In the Occlusion generation I use the Settings the Mod Guide shows. Allways when the generation is completet I got this error: A Occlusion.esp and a BSHeartland.esm.save.xxxx_xx_xx_xx_xx_xx is generated in my Overwrite folder. Thanks for the Help.
  9. @sheson Looking for some direction. I believe Draco's Alternative Aspen Trees does not support hybrid trees. I like the aspen models and have modified the textures. LOD tree trunks are white and pop in when close enough in game. I believe that I need to modify the models of the 'billboards' as the mod creator calls them in the downloads. First: am I correct in my assumption that I must modify the models? Second: I am having issues following your workflow ... ../DynDOLOD/Docs/trees.ultra/tools/DynDOLOD_CreateStaticTree.html... and will post details on that once I determine if I am even on the right path ... or you can point me to previous Q&A on that in these forums. Thanks
  10. I have read pertinent instructions and am a bit confused as to the use of XLodGen. I am aware of the three distinct sections of XlodGen (Objects, Trees, and Occlusion) i.e. When and for What should XlodGen be used? Does XlodGen have any useful place if using TexGen and DynDOLOD? Thank you!
  11. Sheson, I have a couple of questions about using your tools correctly. I've been told quite different things by several very experienced SSE mod devs and would appreciate your definitive input. 1) I was told there is an advantage to using both LODGEN (for terrain) -and- DYNDOLOD (for objects) in SSE. I currently just use DYNDOLOD, since it appears to be a strict super-set of LODGEN? 2) The Oldrim DYNDOLOD OpenCities instructions call for doing 2 passes (static options w/o OpenCities & Blowing in the Wind and not saving; then dynamic options with everything and saving), BUT this section appears to be omitted in the SSE DYNDOLOD instructions. Should I continue doing SSE DYNDOLOD in 1 pass, since it appears to detect OpenCities for some settings at runtime in the logs, -or- two passes as described in the Oldrim instructions? Thank you for your efforts on these great tools and your time in answering our questions.
  12. Placehoder. We'll be discussing DynDOLOD settings, requirements, and relationship to other LOD gen processes like TexGen and xLODGen.

  14. Hello, Firstly, I hope I'm posting this in the correct support forum. If not I'm sorry, didn't know where else to go. I'm having a strange issue after running SSELodGen wherein it completely screws my map up visually and makes it impossible to move around, since the camera speeds up too quickly. I am unable to visually see the flat map I installed nor the actual land mass. If I disable the LodGen output it works normally. I've included some short videos to demonstrate what I mean: LodGen Output disabled - LodGen Output enabled - Thank you.
  15. For Terrain LOD Generation, there are four options available for people to use. LOD4, LOD8, LOD16, and LOD32. What would be the recommended setting to use for generating the water and terrain?
  16. Just looking to understand the differences between the LOD levels in the Xlodgen GUI and the impact of the choices on the game.
  17. Hello, I'm currently following Lexy's guide. I'm at the stage of generating Terrain LOD during the finishing stage. The SSELOGen process freezes after a few minutes and I get the following error at the beginning: [00:00] Generating LOD[00:00] [Tamriel] Generating Terrain LOD[00:00] [Tamriel] Gathering CELL and LAND records[00:05] [Tamriel] Land height: -27000, Water height: -14000, Scanned: 16384 CELL records, Found: 16384 LAND records for area [-64,-64] to [63,63][00:05] [Tamriel] LODsettings: Level 4 to 32 stride 256 from -96,-96 to 0,0[00:05] [Tamriel] Exporting terrain mesh data for LODGen to G:\SMT\xLODGen\Edit Scripts\LODGen_Terrain_Tamriel.bin[00:13] [Tamriel] No options file found: G:\SMT\xLODGen\Edit Scripts\SSELODGen_Skyrim_Tamriel_Options.txt[00:13] [Tamriel] Saving LODGen data: G:\SMT\xLODGen\Edit Scripts\LODGen_Terrain_Tamriel.txt[00:13] [Tamriel] Running "G:\SMT\xLODGen\Edit Scripts\LODGenx64.exe" "G:\SMT\xLODGen\Edit Scripts\LODGen_Terrain_Tamriel.txt"[00:13] Can not write to G:\SMT\xLODGen\LODGen_log.txt[00:13] [Tamriel] Terrain LOD meshes generation error: LODGen process error, exit code 00000193 Any help would be greatly appreciated!
