This merged plugin can be used as the `input` plugin for Lawnmower, saving you the trouble of running the script on individual mods. + +## Utilizing Autoclean Plugins + +Autoclean plugins can be used to increase the accuracy of Lawnmower in detecting clipping groundcover. + +Lawnmower comes packaged with two autoclean plugins: + +- `autoclean_cities_vanilla.esp`:   For Vvardenfell cities +- `autoclean_cities_TR.ESP`:   For [Tamriel Rebuilt](https://www.tamriel-rebuilt.org/) cities + +These plugins utilize the invisible marker meshes from [[the-lawnmower#Grassblocker|Grassblocker]], which `lawnmower.py` treats as objects when detecting whether grass is clipping. The plugins place these meshes in common areas where unwanted grass is often generated by [[mesh-gen|Mesh Generator]], but which otherwise won't be detected by `lawnmower.py` unless an object covers the area - i.e., a Grassblocker mesh. Mod makers can also create Lawnmower autoclean patches for their own mods using Grassblocker. + +The syntax for cleaning a groundcover plugin with an autoclean plugin is the same as any other: + +``` +python lawnmower.py autoclean_cities_vanilla.esp "my grassmod.esp" "my grassmod_out.esp" +``` + +## Advanced - Cleaning the Plugin + +The caveat to The Lawnmower is that it does not truly delete the grass references it detects. + +Instead, it moves their coordinates to `X: 0`, `Y: 0`, `Z: -20,000`, far below the surface of the game world. As groundcover plugins contain tens of thousands of references, these moved references are still taking up file space, even if they are never encountered in-game. Deleting these will not improve performance markedly, but it can make analyzing the output plugin easier. + +With a couple of extra steps, the reference count of the output plugin can be greatly reduced. + +> [!Note|txt-s right wm-sm] Note on Performance Impact +> Deleting the references likely will not offer any noticeable performance gain, beyond marginally improving plugin load speed upon launching the game. +> +> However, it does make it easier to analyze the output plugin later by removing redundant data, for example: +> +> - Viewing modified cells in [[CSSE]] or [[modding-tools/low-level-editors/index|low-level editors]]: Cells containing only grass moved by Lawnmower will no longer appear as modified. +> - Viewing a text representation of the plugin created by Tes3cmd `dump`, Tes3conv JSON or [[deltaplugin|DeltaPlugin]] YAML: Cleaning the plugin 'declutters' it so redundant data does not clutter the results. + +Cleaning the output plugin of redundant `CELL` references involves two steps: + +1. Delete the moved grass with [[tes3cmd|Tes3cmd]]. +2. Clean the plugin of any empty cells with [[testool|TESTool]]. + +The second step is useful for instances where Lawnmower has removed all grass from a cell, leaving an empty `CELL` record. + +### Step 1 - Tes3cmd + +Thankfully, the moved references have one unique thing in common: their coordinates have all been moved to `Z: -20,000`. + +The following Tes3cmd `delete` command will delete all the moved references: + +```tile="tes3cmd 'delete' command" +tes3cmd delete --instance-match "Z\:-20000" +``` + +Replace `` with your plugin name. + +### Step 2 - TESTool + +TESTool can clean empty cells which are otherwise not considered by Tesecmd as 'junk cells'. + +Simply run TESTool `Clean ESP/ESM files` on the output plugin. + +## Further Reading + +- [[the-lawnmower|The Lawnmower]] +- [[mesh-gen|Mesh Generator]] +- [[habasi|Habasi]] + +[^1]: "Python for Beginners: Installing", Python.org, accessed August 24, 2024, https://www.python.org/about/gettingstarted/ \ No newline at end of file diff --git a/mmw-content/index.md b/mmw-content/index.md index 6b276ea2..62c2f39b 100644 --- a/mmw-content/index.md +++ b/mmw-content/index.md @@ -16,6 +16,8 @@ Completed articles so far include: - [[esp-replacer-patch-beginner-tutorial|ESP-Replacer Patch Beginner Tutorial]] - [[morrowind-interiors-project|Morrowind Interiors Project]] - [[simple-texture-animation-in-blender|Simple Texture Animation in Blender]] +- [[the-lawnmower|Lawnmower]] +- [[lawnmower-tutorial|Lawnmower Groundcover Tutorial]] Work-in-progress articles: - [[creating-a-patch-for-an-esp|Creating a Patch for an ESP]] diff --git a/mmw-content/modding-tools/generating-groundcover/the-lawnmower.md b/mmw-content/modding-tools/generating-groundcover/the-lawnmower.md index 3a851bef..f7d09cfb 100644 --- a/mmw-content/modding-tools/generating-groundcover/the-lawnmower.md +++ b/mmw-content/modding-tools/generating-groundcover/the-lawnmower.md @@ -3,24 +3,103 @@ title: The Lawnmower aliases: - The Lawnmower - Lawnmower + - Weedwhacker + - Grassclipper + - Grassblocker tags: - Lawnmower -description: + - Cleaning-Mods + - Groundcover +description: A tool for cleaning groundcover mods of excess grass using Python scripts and Tes3conv. +parent: "[[modding-tools/generating-groundcover/index|Generating Groundcover]]" +related articles: + - "[[lawnmower-tutorial|Lawnmower Groundcover Tutorial]]" --- +![[lawnmower-for-morrowind-banner.webp|sban]] + ![[maintenance-expand-article#^6fc39d|clean]] ## About -> [!infobox] +> [!infobox|n-th] > > ## The Lawnmower > -> %%![[insert image]]%% +> ![[lawnmower-for-morrowind-logo.webp]] > -> ### Table Heading +> ### Details > > | Type | Name | > | --- | --- | -> | Row | Row | -> | Row | Row | \ No newline at end of file +> | **Links** | - [NexusMods](https://www.nexusmods.com/morrowind/mods/53034)
