About Step
Created by TheCompiler (Daniele Ferraro), Step is a collaborative project with input from the modding community, technical volunteers, and project administrators. The goal is to provide tested and validated methods for establishing and maintaining an enhanced modded Skyrim. Thus, the Guide provides detailed, well-tested build instructions for a solid modded Skyrim that achieves an enhanced, vanilla experience. It's meant to be installed in its entirety and not piecemeal.
The Step team collects information from the modding community through extensive mod testing, detailed reviews, feedback, and suggestions exchanged on the Step Community Forums. Posting rules apply, so be sure to read and follow them. Engage and enjoy a warm welcome and plenty of high-quality support from a large community of experienced members.
New to Modding?
We recommend that you ...
- read through this Guide at least once before attempting installation.
- follow all linked guides and read through them, as well.
There is a lot of information to absorb and learn in order to successfully build a modded game. We and the community, have brought together a lot of this information into guides as a free and hopefully convenient resource for all. New and experienced modders alike will find many answers within these guides and linked resources. This Guide is written in such a way that it expects users to know the basics of modding and related tools (e.g. mod managers, LOD optimizers, configuration utilities, etc.). However our support forums are always available for our users.
Nomenclature
The following nomenclature is used throughout this guide and should be understood before proceeding.
- 'tick' means 'check': Frequently, the word 'check' or 'checked' can mean 'ensure' in addition to "check mark", so 'check' is not used where it is synonymous with 'tick' to avoid any mistakes that can (and have) happened from this conflation.
- Baseline: An installation of a mod using the recommend file option listed within the Baseline column of the mod tables below.
- Step Patches: A "patch" is a plugin that allows two or more mods to work together without conflicting. The Step Patches are such plugins, but allow all of the mods in the Step Guide to work harmoniously together. Some users refer to this as a conflict resolution patch or "CR Patch".
Minimum System Requirements
We recommend the following hardware configuration for running a Step Fallout4 installation at a resolution of 1920x1080 on Ultra-like settings. The minimum requirements will allow most users to install and run the Baseline options, which match Fallout4's recommended requirements. Our recommended requirements below will allow most users to install and run the Guide using higher quality options with all of the Guide's optional components (Lighting & Weather, ENB, etc.).
Users wishing to install high quality options at resolutions higher than 1920x1080, be advised a more powerful system will likely be required than what is listed below.
Hardware | Minimum | Recommended |
---|---|---|
Windows OS | Windows 10 64-bit | Windows 10 64-bit |
CPU | Intel Core i5-7600 / i7-4790 or equivalent | Intel Core i5-8600 / i7-8700 or equivalent or better |
System RAM | 8 GB | 8 GB or higher |
GPU | Nvidia GTX 970 or equivalent | Nvidia GTX 1060 or equivalent or better |
Drive Space | ~65 GBs (includes game+guide) | ~75 GBs (includes game+guide) |
Monitor Resolution | 1920x1080 | 1920x1080 or higher |
Time Requirement
Users should be aware that it will usually take anywhere from several hours to a several days to complete this Guide from start to finish. Since this is a start to finish process, a recommend schedule for completing it is:
- Day 1 : Steps 1 - 3
- Day 2 : Step 4
- Step 4 is installing all the mods. Depending on download speeds and previous modding knowledge, this step could span 1-3 days.
- Final Day : Finish the remainder of the Guide.
The overall message here is that Step encourages users to always follow proper computer ergonomics when modding! Remember to take breaks and happy modding!
STEP 1
Follow the System Setup Guide!
Those who have not completed the System Setup Guide should STOP and do so now BEFORE continuing this guide! This is a perquisite for completing any of the Step Bethesda mod-build guides.
NEW GUIDE FOLLOWERS: Deviate from these instructions at your own risk! Instructions in this guide presume that previous instructions have been followed.
STEP 2
Mod Organizer - Fallout 4 Initialization
FIRST, follow the System Setup Guide. The below instructions describe how to initialize a Fallout 4 instance in Mod Organizer (MO). If MO wass installed as a Portable application, the instructions below will need to be reinterpreted accordingly. Those who already have a MO instance for Fallout 4 can skip this initialization:
Profile Setup
Mod Organizer's profile feature allows the creation of multiple mod-builds. Begin by creating/editing two profiles for use with this guide:
Tool Setup
All tools installed in the System Setup Guide should be added to MO. Some tools will have been auto-detected and added; however, ensure the settings below are set correctly for all tools. xEdit is used in this example:
Tool Setup Reference for Fallout 4
Application Title | Executable | Argument(s) |
---|---|---|
xEdit | xEdit.exe | -FO4 -IKnowWhatImDoing Tick the Create files in mod instead of overwrite box and select the xEdit Output mod from the drop-down. |
xEditQuickAutoClean | xEditQuickAutoClean.exe | -FO4 Tick the Create files in mod instead of overwrite box and select the xEdit Output mod from the drop-down. |
LOOT | LOOT.exe | --game="Fallout4"
|
xLODGen | xLODGenx64.exe | -fo4 -lodgen -o:"DriveLetter:\Modding\Tools\xLODGen\xLODGen_Output" Replace DriveLetter: with the drive letter of the 'Modding' folder. |
Users can arrange the tools in any order using the up and down buttons above the list. This will dictate the order that tools are listed in the MO "Run" dropdown menu. Close the window by clicking the [OK] button.
BethINI Setup
BethINI needs to be run for the current MO profile to establish the configuration files before beginning mod installation. This ensures that all users share a common configuration during the modding process. As such, please do not deviate from the instructions below. Once the guide is complete and things are confirmed to be working, there's an optional BethINI setup located at the end of this guide that can be used to fine tune the configuration.
BethINI Initialization
BethINI Basline Configuration
Users should now continue through each of the tabs within BethINI, matching the screens below. Again, please do no deviate from these instructions at this time. Click the header to see important notes:
➕ [Click to show]➖ [Click to hide] Basic |
➕ [Click to show]➖ [Click to hide] General |
➕ [Click to show]➖ [Click to hide] Gameplay |

➕ [Click to show]➖ [Click to hide] Custom |
STEP 3
LOOT
At any time during the mod installation process, LOOT should be used to sort plugin load order before running the game. This is necessary to ensure proper plugin priority (load order), which can have a dramatic impact on the game. Users not running the game during the mod installation step of the Guide can wait to sort after this step is complete. To sort with LOOT:
- Launch LOOT via Mod Organizer 2 from the executables drop-down menu at the top of the right pane.
- If LOOT fails to start, try adding the following argument as described in Tools Setup:
--single-process
. If LOOT cannot find the game directory, add the path to../Fallout 4
folder to Installed Path under LOOT settings.
- If LOOT fails to start, try adding the following argument as described in Tools Setup:
- Click the [Sort Plugins] icon at the top of the LOOT window.
- Several plugins will show warnings. The next section describes how to clean them up.
- Click [Apply] button, which has replaced the Sort button at the top.
- Close LOOT.

NOTE
When running LOOT before completing the Step Guide, additional warnings may be indicated. These will all be addressed by the end of this Guide.Up to this point, users should only have the following plugins, in the order listed:
- Fallout4.esm
- DLCRobot.esm
- DLCworkshop01.esm
- DLCCoast.esm
- DLCworkshop02.esm
- DLCworkshop03.esm
- DLCNukaWorld.esm
- DLCUltraHighResolution.esm
If the plugins are not in the order listed, run LOOT now.
Cleaning Vanilla Master Files
Step no longer recommends cleaning the vanilla masters, since this has always been unnecessary. See the relevant posts for details and further reading. We continue to provide general plugin cleaning instructions for those mods that may require it.

NOTE
For those that have previously-cleaned vanilla masters, please feel free to continue using them. It is also fine to revert to the uncleaned vanilla masters. Effectively, there is no difference.Standard Cleaning Procedures
Understanding the Step Patches
A “conflict resolution” patch, or CR Patch, is a plugin that resolves conflicts between various active plugins. They allow users to use various mods together without any major issues, while still achieving the desired outcome from the mods. Thus, the Step Patches are one part patch and one part mod.
The Step Patches are built specifically for the Step mod list. They are required to run the this Guide and are dependent on specific mods within the mod list (those tagged at left with a green vertical bar). They will not resolve conflicts with any applicable mods that are not within the Guide's mod list, though.
Step Patches
- Step Fallout4 - Conflict Resolution Patch (Step CR Patch)
- For those that would opt for their own custom lighting and weather mods
- Patches all applicable mods except for Lighting & Weather mods
- Required for all users!
- Step Fallout4 - Lighting & Weather Patch (Step LW Patch)
- For those that are using Guide's lighting and weather mod from the Lighting & Weather mod group.
- Patches only the applicable Lighting & Weather mods; the CR Patch is still required!
STEP 4
At this point, the PC modding environment should be fully set up and ready for mod installation. Those unfamiliar with using MO2 should return to that guide for a refresher. When installing mods, keep the following in mind:
- To maintain compatibility with downstream Patch instructions, it is important to install Patch-related mods as described in their respective Notes.
- After installing a mod, enable the mod in MO.
- If no Notes or Step recommendations are provided for a particular mod, all options are good. Step encourages user customization.
- Mods should be arranged in MO in the order that they are listed to ensure other mods further down the list overwrite/override those occurring before them. This is necessary to ensure the desired outcome.
- Mods are listed in alphabetical order within each Mod Group and any deviations from this are purposeful to achieve the desired outcome.
- Always install plugins (ESLs/ESMs/ESPs), unless otherwise noted. When there is a choice between ESL and ESP, always choose ESL unless otherwise noted.
- Always follow LOOT's advice in regards to mod cleaning and sorting unless otherwise noted.
- Step does not recommend extracting BSAs as a general principle, since it adds to the potential for user error and unnecessary support issues. Experienced and self-supporting users may derive benefit from doing so, however.

MO2
MO Separators: Mod Organizer features the ability to create separators within the mod list to group mods for easier visual reference. Step recommends using these separators for each Mod Group following below. To create a separator:
- Click the
button on the top of the mod list pane.
- Select [Create Separator] and give the separator a name. Step recommends using the Mod Group names (i.e., Extensions, Resources, Lighting & Weather, etc.).
- Create a new separator for each new Mod Group while working through the Guide.
- Separator colors can be customized by right-clicking on any separator and selecting Select Color.
Mod Table Reference
Below is the legend and reference for the mod tables used in this Guide. Users should refer back to it when confused about a mod listing.

Mod List Cleanup & Performance Check
Final Sorting and Cleaning
Before moving on, run LOOT from MO, then sort, and accept the default load order provided. Review the mod list in LOOT looking for any plugins reported as needing to be cleaned. Keep in mind that LOOT tends to lag behind on the report information, so it will not always be accurate. Ignore any reported missing compatibility patches or other warnings. These are either handled by the Step Patches or not of any concern. Perform the standard cleaning procedures on the mods requiring cleaning.
Be aware the Step Patches are designed to work with a default, LOOT-sorted plugin order. This eliminates the need to set rules on the load order. From this point on:
- Ensure all applicable mods are ticked in the left pane of MO.
- Ensure all plugins are ticked in the right pane of MO.
- Sort the load order using LOOT whenever plugins are added/removed.
- Update LOOT (the program and masterlist) whenever updates are available.
Performance Tuning
The goal at this point is to have at least 80 FPS in exteriors on average. It's necessary to determine how much performance headroom is available before generating LOD, because the full LODGen setup can cost upwards of 30 FPS on average in exteriors. Before beginning, uncap FPS if it was configured in SSE Display Tweaks or via the driver software so that actual frame rates can be measured. Some users may by required to turn of vsync to measure above 60FPS. These changes should be reversed when FPS performance is no longer a concern.
It's recommended to turn on the On-Screen Display (OSD) settings in SSE Display Tweaks to measure FPS. Other third-party applications like FRAPS, Skyrim Performance Monitor (SPM), and even driver software can be used but are unnecessary with SSE Display Tweaks. Optional instructions are provided to assist.
Performance/Quality Optimization
There are many things that can be modified to improve performance and quality, depending on the performance headroom available. Following are some suggestions listed in descending priority:
- Consider revisiting the BethINI Setup to set the 'Low', 'Medium', 'High', or 'Ultra' preset until FPS is close to or greater than 80 FPS while looking West across the tundra outside of the Whiterun main gate. NOTE: Changing the preset revises View Distance, so be certain to change "Level 16" to 300000.
- Consider modifying the following grass settings in GrassControl.config.txt of the No Grass In Objects mod:
- Set
ExtendGrassDistance = False
andOverwriteGrassDistance = 6000
or less to improve performance. Increase the latter value to improve quality at the cost of performance. - Don't forget to also lower
OverwriteGrassFadeRange
to some value less than 6000 (like 3000). - Set
OverwriteMinGrassSize
to a value of 50-20 to improve quality (default of '60' is already the performance optimum, but it can be increased further to optimize the quality-performance trade-off).
- Set
- If FPS is at least 80 in the test area, then consider enabling grass LODGen (addressed below, including screenshots)
STEP 5
We wish to be clear that this section is completely optional. All is still within the Mandate, however, we've made this section optional for users who wish to customize their own custom post-processing. As such, we've included an additional patch solely for this section's mod group.
Using Cathedral Minimalist ENB as a starting point, the Step Team built an ENB Preset specifically tailored to the mod list with this Fallout4 Guide. Two different configurations are available for use. The Milk-Drinker configuration is designed to be light-weight; costing 5-10FPS. It is tailored to be used by the majority of Guide users to fix many of Fallout 4's lighting issues while bringing in some additional enhancements and features. The Dragonborn configuration is the fully designed Preset with all the desired effects and features enabled. It will cost ~20FPS outdoor.
- If average FPS is between 75-90 (HINT: check in the Rift and the Frozen Marshes), Step recommends installing the Milk-Drinker configuration.
- If average FPS is > 90, Step recommends the Dragonborn configuration. Keep in mind that LOD generation is more important to visual enhancement than ENB.}}
No mods defined.
STEP 6
Now that all the mods and patches have been installed/sorted and performance margins are acceptable, the next step is to generate custom LOD data for the mod list. Recommended settings correspond to rendered game resolutions that can benefit. Using 'higher' settings will otherwise be a waste of PC resources that may be necessary to keep frame rates above 50 FPS. Use 'lower' settings as a compromise if necessary. Any time a mod providing LOD assets is added, removed, or changed, LOD should be regenerated. Examples include --but are not limited to-- most of the '03-Foundation' mods, No Grass In Objects, Enhanced Vanilla Trees, Just Ice, etc.
Before moving on, create three empty mods for the LOD output:
- Click on the
button and select, [Create empty mod].
- Name it
(TEMP) - SSE Terrain - Tamriel - xLODGen
(this will only be used as a resource for xLODGen).- This places a new, empty mod at the bottom of the mod list. However if it's not, place it last in the mod list.
- Repeat these steps to create three other new mods named:
Step Fallout4 - xLODGen Output
,Step Fallout4 - TexGen Output
, andStep Fallout4 - DynDOLOD Output
; or anything unique and descriptive to their source/function. - Place these new mods directly after (TEMP) - SSE Terrain - Tamriel - xLODGen.
- Find the (TEMP) - Cathedral Landscapes - LODGen mod from the 04-Foundation mod group and enable it if it is not enabled. This mod ONLY needs to be enabled for terrain LOD generation. If it is not disabled before actually playing the game, it will cause visual glitches.
The last few mods in the mod list should now reflect the following (numbering is approximate and reflects the number of mods installed without extra mods or mod-list separators):
- DLC: Hearthfires
- ...
- (TEMP) - SSE Terrain - Tamriel - xLODGen
- (TEMP) - Cathedral Landscapes - LODGen NOTE: This mod can be here or under 04-Foundation with Cathedral Landscapes main mod, but it must be DISABLED later as instructed!
- Step Fallout4 - xLODGen Output

NOTE
Complete the following in order, and ensure that all mods are enabled and plugins enabled and sorted!xLODGen
xLODGen is run first to generate updated LOD terrain textures and meshes so that landscape LOD is updated with mod changes:
Preparation
Generation
Wrap Up
When to Regenerate LOD
- xLODGen
- Whenever there are changes to the mod list that affect the underlying landscape: height, shape, textures, etc. This does not include grass, mountains or other objects on the landscape.
STEP 6
Step Fallout4 is fully installed and working at this point, but if FPS are < 60 or > 80, some adjustments may be beneficial to performance or quality. A final consideration is customizing BethINI. Refer to the Skyrim Configuration Guides for more information.
STEP 7
The game is now ready to be loaded to configure mods in the Mod Configuration Menu (MCM). The MCM is a feature of SkyUI that allows mod authors to provide custom, game-accessible settings for their mods. Recommendations are provided below for select mods. The remainder are user preference.
First Launch
To run the game, select the F4SE Launcher executable from the drop-down list and click the Run button. Keep the following in mind when first launching from a fresh Guide installation:
- A new game is required!
- In other words, don't load from a save when first launching after a fresh guide install to avoid issues. Review the changelog before upgrading from a previous version of this Guide to determine whether or not a new game is advisable.
- When launching the game for the first time after a Guide install, the load could take significantly longer than normal. This will only be a one-time wait as all the installed mods are being initialized. Subsequent load times should be shorter.
- Finally, INI files may appear in the Overwrite folder after closing the game (e.g.
../SKSE/Plugins/SkyrimUncapper.ini
). These files should be moved to their respective mod folders, respecting their folder structure during the move.
Alternate Start
Upon starting a new game, the Alternate Start - Live Another Life is the first mod in play. Lets face it, Fallout 4 is old and the vanilla start quest is the last thing many want to play through. Alternate Start provides a variety of ways to start the game. Once a new game is started, a locked cell is loaded. Simply talk to the statue in the room, choose a preference for starting the game (the vanilla start is provided as an option), and then sleep in the bed to start your new life. When using an alternate start location, the main quest line can be initialized by simply visiting Helgen.
Mod Configuration Menu Settings
Cathedral Weathers
Users who have installed the optional Lighting & Weathers mod group should set Interior Vision to "Darker" in order for Luminosity to have the correct interior brightness.
Complete Crafting
The following screenshots display the recommended settings for the mod's MCM:
Remaining Mod Configurations
The remaining mod configurations are recommended to be left at their defaults for the most enhanced, vanilla experience. However, users may adjust the settings for these mods to their preference.
COMMUNITY CONTRIBUTIONS
STEP can only get bigger and better with help from the community. It is very time consuming for the STEP team to ensure that the Guide is consistently maintained at the highest quality possible. We need people to help us identify mods that improve the vanilla game while adhering to our Mandate. We also need ongoing bug reports, reviews, and updates on mods that may cause problems or that stray from the Mandate.
In order to suggest a mod for inclusion, visit the Mods section of the Forums.
