bruhcubed Posted December 21, 2023 Posted December 21, 2023 (edited) So I'm using Grass Cache Helper NG, and that mod is great (Thanks Shizof). But when I use grass LODs (which also works great, thanks Sheson), there is a blatant gap between the LOD and the actual cell grass as a result of the grass fading prematurely. Normally, most users can just disable this and have grass load into all cells and this works for many people. But for me, my setup just straight REFUSES to disable grass fade. However, I've discovered that when running this setup on NGIO, there is no gap in the LOD? So NGIO somehow can disable it, but Grass Cache Helper, which does have a setting to disable grass fade(and yes this is correct in the settings ini for that mod) cannot seem to disable it. This is slightly frustrating because I have to downgrade to 1.5, not ideal. Literally the only thing keeping me from 1.6 is this issue of bGrassFade. I have scoured every single ini file, I even disable every mod, deleted and used the default for my ini settings. I've used BethINI, I've manually edited every single ini file that are even adjacent to being relevant to have this ini setting be 0. I've even disabled every single mod and had a setup with just grass and grass cache helper ng to see if there was another mod overwriting the setting. Nothing. For some god forsaken reason, only NGIO seems to disable this setting. Normally, I would be happy to just downgrade to 1.5, something I used to do in the past. But there are some critical mods (for me) which are 1.6 only now, so trying to fix this would be great not just for me, but for the other users that struggling with this under the Grass Cache Helper NG page. If anybody has any ideas, please let me know, I will be glad to test it. Edit: just to be more clear, I mean the bEnableGrassFade setting. Edited December 21, 2023 by bruhcubed
z929669 Posted December 21, 2023 Posted December 21, 2023 Reference the grass LOD guide for relevant INI settings for grass and generating grass LOD for relatively seamless transitions, proper LOD distances, and no gaps. I suggest to use BethINI to ensure your config settings are correct. It sounds like you may be using DynDOLOD grass mode 2 or LOD distance settings are off. Also use the latest DynDOLOD alpha, as some bug with LOD4 affected Alpha 161
DoubleYou Posted December 21, 2023 Posted December 21, 2023 bEnableGrassFade is not the setting you are looking for. That controls a slight fade in effect on cell load. First and most likely possibility is like @z929669 said, perhaps you used DynDOLOD mode 2 instead of mode 1. NGIO only is able to support mode 2. Mode 1 must be used with Grass Cache Helper. Another possibility is that you may need to override the auto calculated grass distance settings in Grass Cache Helper NG with manual tweaking, setting fGrassStartFadeDistance to a higher value like 99999. Another possibility is that the grass mod may not have sufficient alpha mipmap threshold in the textures to be sufficiently visible over far distances. This does not seem likely given that NGIO fixes the issue. It is possible that NGIO has an auto fix for that, but I am unaware of that being the case.
bruhcubed Posted December 22, 2023 Author Posted December 22, 2023 (edited) Hey everybody thanks for the advice, First off, I absolutely used DynDOLOD mode 1. I made certain to do so in all the grass caches I made. I even used working grass caches from others on the nexus on a clean instance. I also use BethINI. I am very familiar with grass caching as this is my 4th go at it, and each time before its worked perfectly. I would like to try overriding this auto calculated value, but as a bit of warning I have tried disabling the values in the Grass Cache Helper NG file in favor of using proper settings from within BethINI, also following the advice for INI values from the STEP guide. Still even if I do that, I still get grass fade for some reason. The only thing I have not tried is the sufficient alpha mipmap threshold. However, I have tried two separate grass mods, both which work for other people. These being Seasonal Landscapes with Unfrozen, and Cathedral Landscapes Complex Grass. So unless both of these mods suffer from insufficient alpha mipmaps, I am fairly certain that this is unlikely. For now, I'll try to override the INI settings and report back with an edit to this post. Thanks again everybody. Edit: well, I tried overwriting the grass distance settings to 99999 in BethINI and I can confirm it does nothing. The grass still fades away right at the edge of the cells before the LOD kicks in. If only I could figure out why it works on NGIO and not on Grass Cache Helper. Oh also, I am using the latest version of DynDOLOD. Before it comes up as well, yes, my ini file location on BethINI is directed to the correct profile in MO2. Edited December 22, 2023 by bruhcubed
DoubleYou Posted December 23, 2023 Posted December 23, 2023 In the in-game console, type and verify that the values of the INI settings are being written to memory correctly. getini "fGrassStartFadeDistance:Grass" getini "fGrassFadeRange:Grass" getini "iGrassCellRadius:Grass" getini "fTexturePctThreshold:Grass" What are the results, and are they as expected?
bruhcubed Posted December 23, 2023 Author Posted December 23, 2023 After checking the ini files and comparing to both what is on file and what is displayed. I can confirm that the results are as expected. Here are the values. fGrassStartFadeDistance: 6144 fGrassFadeRange: 107983 iGrassCellRadius: 2 fTexturePctThreshold: 0 These values were the same across both NGIO and Grass Cache Helper NG, the problem still persists however. Thanks again for the help!

Thanks again for the help! fGrassFadeRange should be 14128. Increasing it to very high values might cause the inverse effect, as it functions by slightly sloping the grass gradually into the ground I believe.
bruhcubed Posted December 23, 2023 Author Posted December 23, 2023 (edited) Here are my settings: Skyrim.ini [Grass] bAllowCreateGrass=1 bAllowLoadGrass=0 bDrawShaderGrass=1 bEnableGrassFade=0 fGrassFadeRange=14128 fGrassMaxStartFadeDistance=7000.0000 fGrassMinStartFadeDistance=0.0000 fGrassWindMagnitudeMax=65 fGrassWindMagnitudeMin=5 iGrassCellRadius=2 iMaxGrassTypesPerTexure=2 iMinGrassSize=35 SkyrimPrefs.ini [Grass] fGrassMaxStartFadeDistance=7000 fGrassMinStartFadeDistance=0 fGrassStartFadeDistance=6144 And here's an image I took a while ago just for context: Imgur Link. I had different settings before but I decided to copy yours. Still does the exact same thing. I also made a "grass test" profile in mo2 and I can confirm that there also no other mods loaded except the essentials to run seasons of skyrim, seasonal landscapes, grass cache helper ng and the grass cache. This has been utterly confounding so if you know anything, it would be greatly appreciated. Thanks in advance. Edit: Also, in regards to the high values, I made sure to double check what the grass fade value was in skyrim after I made the changes to the ini file. The issue persisted however, it outputted the new value of 14128. Unfortunately that ini change did not resolve it. Edited December 23, 2023 by bruhcubed

Also increase iMaxGrassTypesPerTexure to a value of at least seven (for CL, we recommend 15). You have redundant settings in Skyrim.ini, so I recommend that you delete Skyrim.ini, SkyrimPrefs.ini and SkyrimCustom.ini, relaunch the game via Steam launcher, quit the launcher without starting the game, and rerun BethINI according to our instructions. Make certain that your INI paths are set correctly and that no mods are providing conflicting INI settings. If you use MO, it's pretty easy:

If you use MO, it's pretty easy: So I followed this all to the T, ensuring that I deleted all of the files in both the "MyGames" folder and the Grass Test profile folder. I also set the ini paths to the Grass Test folder path after MO2 ended up grabbing a copy of the vanilla settings from the MyGames folder after the I ran it from the steam launcher. Then I imitated exactly every single setting in your link regarding BethINI. Unfortunately, the fade still exists between active cells and lod cells. I also made sure that no mods are providing conflicting ini settings. The only one is the Unofficial Skyrim Special Edition Patch, as I have disabled all other mods, and the ini settings there were not at all relevant.

DoubleYou Posted December 24, 2023 Posted December 24, 2023 I don't know why it isn't working for you. Your settings are all correct. The only thing I can really see is that your grass seems extremely short and stubby in comparison to the grass in LOD. It seems more dense in LOD than in full, which doesn't make sense. Perhaps somehow your grass mod isn't the same as your grass cache? Or your grass cache is from different landscape?
bruhcubed Posted December 24, 2023 Author Posted December 24, 2023 (edited) This line of thought occurred to me as well, but I tried with CL and that did not seem to work either. I already talked about this in depth with Shizof and we were both stumped so I thought STEP might have the answer. One of the only things that I thought of is that it might be hardware based? But I have no idea where that would even begin. If it concerns you, I have an AMD 6750XT. But then why would NGIO work and not Grass Cache Helper? It's all very confusing. EDIT: Additionally, I have tried grass caches from the Nexus and even that did not work with Grass Cache Helper NG. Edited December 24, 2023 by bruhcubed

I would post with DynDOLOD logs on that forum to troubleshoot. Even if it's not LOD, sheson may know something related to this issue. Other than that, did you regen your grass cache using the same setup you are running now?
