📋 About This Mod
Like my other mod, Turn Normal Grass and Kelp Into Groundcover, this mod improves the look and performance of Province: Cyrodiil's pre-alpha version of Stirk by deleting a bunch of plants, then putting them back in a separate grass plugin.
Unlike my other mod, in Stirk's case that means converting over 85% of the original objects into grass. This causes a very substantial performance improvement, particularly near the harbor.
The P:C developers are aware that there is far too much kelp in the water around Stirk, and they are going to fix it in a future release. In the meantime, this mod is meant as a band-aid to make the island playable for people who want to visit the island in its pre-alpha state.
Installation:
How to install
1. If you have any mesh replacers which affect vanilla kelp, you have to duplicate their meshes into this mod's \Meshes\grass\ folder. There is a list of affected files at the end of this description.
2. If you are an OpenMW user and this is your first time adding a grass/groundcover mod, you will need to locate your settings.cfg file, open it in a text editor, find the heading (or create it if it doesn't exist), and add underneath it the line enabled = true (for more information about finding and using your settings.cfg, consult the OpenMW documentation).
3. If this is your only groundcover mod, you should use a grass density setting of 1. 0 to prevent any of the original plants from disappearing entirely. In OpenMW, that means editing settings.cfg, under the heading, to include the line density = 1. 0 and you might also want to increase the rendering distance for groundcover, using a line like rendering distance = 16000 (where one cell of distance = 8192, and the default for this setting is 6144)
4. Enable hm-grass-stirk-GROUNDCOVER.esp as a groundcover plugin:
-
[] If you use OpenMW, this means editing your openmw.cfg file to include the line groundcover=hm-grass-stirk-GROUNDCOVER.esp (Do not enable it in the OpenMW Launcher!!!)
[
]If you use MGE XE, this means generating distant land with hm-grass-stirk-GROUNDCOVER.esp enabled. If this is your only groundcover mod, set the grass density to 1. 0 when you generate distant land.5. Enable hm-grass-stirk-CONTENT.esp as a normal plugin. Do not enable the GROUNDCOVER.esp as a normal mod!
Is it compatible?
[*]It works with both

✨ Key Features
📊 Pros & Cons
✅ Pros
- Direct FPS boost for a notoriously laggy area (49 endorsements, 2.6k downloads)
- Simple concept: separates kelp into its own plugin, so it's easy to toggle
- Active enough to have a small but dedicated following
⚠️ Cons
- Only affects the pre-alpha version of Stirk—might not work with newer builds
- Last updated in 2022—could be outdated if Province: Cyrodiil has changed since
For Morrowind modders who play Province: Cyrodiil and suffer FPS drops in Stirk. If you're exploring that pre-alpha area and want smoother performance, this is a quick fix. Skip if you don't use Province: Cyrodiil or don't care about Stirk's kelp forests.
💡 Beginner Tips
- Make sure you have Province: Cyrodiil installed and the pre-alpha version of Stirk active before adding this patch.
- Load this plugin after the main Province: Cyrodiil files to ensure the kelp override works.
- If you notice missing kelp visuals, check that the grass plugin is enabled in your mod manager.
