Problems getting Nemesis to run through MO2

[Jotasran]

I'm trying to setup Skyrim through MO2... something I've always found to be a complete pain in the ass despite everyone who knows more than me saying its better than Vortex..

 

Anyway, I'm using the STEP guide for now will sex up my mods later... for now.  I followed these exact steps...

 

Install the Main File.

Add to Mod Organizer Executables

Nemesis is run through Mod Organizer like most other tools. Add Nemesis to the list of executables by doing the following:

1. In the right pane, go to the Data tab.
2. Locate the Nemesis_Engine folder and expand it.
3. Right-click the Nemesis Unlimited Behavior Engine.exe file and select [Add as Executable].
4. In the window that opens, type Nemesis for the title.
5. Click [OK].

Create Mod for Output

It is recommended to create a mod to store output files from Nemesis by doing the following:

1. Click on the button and select, [Create empty mod].
2. Name it Step SkryimSE - Nemesis Output.
3. Open the Executables menu and choose [Nemesis].
4. Tick the Create files in mod instead of overwrite (*) checkmark and select Step SkryimSE - Nemesis Output from the dropdown.
5. Click [Apply] and then [OK].

Run Nemesis

Nemesis must be run whenever animation/skeleton mods are added/updated. To do so:

1. Ensure all plugins are ticked, and sorted with LOOT.
2. Choose Nemesis from the executables dropdown and click [Run] to run it through Mod Organizer.
3. Tick the Ice skating fixed for real box.
4. It may be necessary to click [Update Engine] and wait until the progress bar has finished.
5. Click [Launch Nemesis Behavior Engine] and wait until it says "Behavior generation complete" and close.

 

When I try to run Nemesis, the list with check boxes doesn't come up.  I get a counter the says "preparing vfs" that fills quickly and vanishes.  No output appears to be going into the Step SkyrimSE - Nemesis Output folder.  as it is still greyed out (yes, it's checked).

Why Nemesis? Pandora is easier, but it's my subjective opinion. 

 

Download Pandora. Install it as mod. Expand in right side executable panel -> Edit. Locate your Pandora.exe file and add it as executable. Run Pandora through MO2 after installing animations which need to be "set up" with Pandora.

When I tested this just now it set the working directory to the one where the executable is actually installed. You most likely need to set it to the one where it would be when running through the usvfs:

 

"...\MO2\Mods\Nemeis-some-version" -> "...\Skyrim Special Edition\Data\Nemesis-some-version"

"...\MO2\Mods\Nemeis-some-version\the\rest" -> "...\Skyrim Special Edition\Data\the\rest"

Sounds like you don't even get to see the Nemesis window. Smells like its crashing or otherwise terminating. This seems more like a Nemesis issue than MO2. I'd start with either Process Monitor or the Windows Event Viewer. See if there's any thread and file io activity in Nemesis, and whether or not there's any appcrash log entries.

Because I don't feel that I know enough to make a decision like that when the STEP guild is telling me to use Nemesis.  I may try Pandora later but doubt I'll get any STEP support if I'm not using their initial suggestions.  Thanks for the advice though.

It's just a guide. You can test Nemesis, of course. But you can switch to FNIS or Pandora of you want. As I know, FNIS can handle lower count of animations. I have Pandora with about 18 000 animations

LOL.  I have no idea what a usvfs is.  I can follow directions but don't really understand this.   I think I understand you to mean that the "Binary" should not point to AppData\local\modorganizaer\skyrim\modsProject New Reign\Nemesis...exe but rather the folder in the C:\games\steamapps folder but there isn't and nemesis executable there.  Seems like the only Nemesis exe is in the appdata folder structure.

Working directory is different from the exe. Leave the exe path as it is, just change the working directory.

 

usvfs = User-Space Virtual File System. It's a file IO redirection library running in ring 3 used by MO2 to "install" mods as it were.

By working directory, do you mean the "Start in" field? 

 

[traison]

Yup.

 

In theory it shouldn't matter what the working directory is set to, but considering what you have to do to find where Skyrim is installed, it's somewhat likely utilities would be using relative paths - in this case the working directory is essential to locating game data files.

Ok... in the "Start in" field, I've browed to steamapps\common\Skyrim SE\Data and only see two folders....  ShaderCache and Video.  There is nothing else to browse to.

[traison]

Type it in. These files and directories only exist from the point of view of the application that runs within the usvfs.

 

Edit: and my previous example was wrong:

 

"...\MO2\Mods\Nemesis-some-version\Nemesis" -> "...\Skyrim Special Edition\Data\Nemesis"

 

The mod directory name is not visible anymore from within the usvfs.

Type it in

Binary is now:   C:\Users\xxxx\AppData\Local\ModOrganizer\Skyrim Special Edition\mods\Project New Reign - Nemesis Unlimited Behavior Engine\Nemesis_Engine\Nemesis Unlimited Behavior Engine.exe

 

Start in is now:  C:\Games\steamapps\common\Skyrim Special Edition\Data\Nemesis Unlimited Behavior Engine.exe

 

It skill behaves the exact same way... the counter fills up and vanishes. 

[traison]

Working DIRECTORY:

 

C:\Games\steamapps\common\Skyrim Special Edition\Data

 

Edit: Also on an unrelated note. Be careful with that path length. Microsoft has claimed for decades now that they've fixed the 255 MAX_PATH length limit, but in practice there's still situations where you run into it. Your current Nemesis path, exe and redacted username included, is 175 characters long. Might bite you in the ass later, depending on how all the applications in this ecosystem were made.

Still no luck.  No change in behavior.

[traison]

Alright in that case I'd have to see this problem myself. RustDesk, PM me if this seems reasonable to you.

[traison]

@Jotasran was kind enough to let me borrow their machine for an hour or so. We got Nemesis running by moving it (and all mo2 mods) out of the AppData directory (default path for MO2 mods I guess) to a custom made directory outside of the Windows controlled ones (i.e. not in the user profile, not in Program Files).

 

My guess right now is that OneDrive was messing it up. The way the problem appeared in ProcMon however was strange, so this is just a guess. Guess based on pervious experience.

[Jotasran]

Thanks so much for going so far out of your way to get me up and running.
