PlantBiomeHeeler

The biome Valheim shows on your HUD/minimap isn't the one your plants actually use. Your HUD reads a 12 m grid right under your feet but plants take a weighted vote from the four corners of whatever 64 m zone they're in. These two grids never line up. Thus, especially near a border those two disagree, and you will think you are planting in plains but actually be in mistlands.

PlantBiomeHeeler paints the plant biome onto the ground around you with solid borders where it flips, plus a little HUD for whatever you're aiming at and where you're standing.

Client only and never touches your world - should work on any server, too.

How Plants Choose a Biome (Based on reading the games assemblies)

• Every 64 m zone has a biome stored at each of its four corners and plants in it go with a weighted vote of those - closest corner usually wins.
• Plant biome ends up changing in rough 64 m squares around the zone corners, nothing to do with the border on your map.
• The mod calls the same game function plants do during their health tick (Heightmap.GetBiome).
• HUD is exact, based on feet location and aiming crosshair location. Overlay borders are within a few centimeters pretty much everywhere - technically could be more accurate with 100s of more lines of code, but this is good enough. Don't plant ON the borders and you will be fine.

Features

• Plant biome overlay: Colors the ground around you by plant biome - see-through fill and a solid two-tone border with a strip in each biome's color. Hugs the terrain (or the water) and fades out toward the edge.
• Hatch lines: Diagonal lines across each biome in its own color for when a fill blends into the ground too much - off until you flip on EnableHatchLines.
• Cultivator display: Pull out the cultivator and the overlay comes up. Don't want that? Set ShowOverlayWithCultivator to false.
• Toggle key: Left Shift + P shows or hides it any time, cultivator or not... as long as you're not holding any other key (stop walking first). If the cultivator brought it up, putting the cultivator away hides it again unless you hit the key in between.
• Biome HUD: Little panel near the top of the screen with the plant biome under your crosshair (Target) and where you're standing (Standing), same colors as the overlay. With a placement ghost out Target follows the ghost - that's exactly where the plant lands.
• Overlay, HUD, or both: EnableOverlay kills the overlay and HudMode picks Always, WithOverlay (default) or Disabled for the HUD. HUD only? Overlay off, HUD on Always.

Configuration

Settings and the toggle key can be changed live using the BepInEx Configuration Manager (installed separately) or by editing BepInEx/config/dreamwraith.PlantBiomeHeeler.cfg. The mod reloads the file when it is saved, without a restart:

Section	Sync Policy	Description
General	Client	Master enable toggle, overlay toggle, automatic display with the cultivator, HUD mode, and log level.
Overlay	Client	Overlay radius, height above the ground, interior and border opacity, border width, and hatch lines.
Biome Colors	Client	Color for each biome. Alpha sets the opacity of the colored area inside the biome.
HUD	Client	Screen offset from the top-left corner, font size, background color, update interval, and Target ray distance.
Keybindings	Client	Toggle key for the overlay.

Sync policies: All settings are client settings. They are never synced and stay under each player's control.

Key Settings

Setting	Default	Description
EnableMod	true	Master enable toggle.
EnableOverlay	true	Draws the plant biome overlay.

Building from Source

Prerequisites:

• .NET SDK.
• A Valheim install. Standard Steam paths are detected automatically.
• The Jotunn prebuild publicizes the game assemblies on the first build. DoPrebuild.props turns it on.
• Build the .sln, not the .csproj. A direct .csproj build skips Environment.props and DoPrebuild.props.

Build using the .NET SDK:

dotnet build PlantBiomeHeeler.sln -c Release

The compiled assembly is output to bin/Release/net48/PlantBiomeHeeler.dll. Building with the Release configuration also creates a distribution zip in bin/Publish/.

Custom Paths

For custom installations, non-standard Steam paths, or mod manager profiles, copy Environment.props.example to Environment.props in the project root to configure your paths:

• VALHEIM_INSTALL: Root Valheim installation folder.
• BEPINEX_PATH: Root BepInEx folder (containing core, plugins, etc.).

Alternatively, you can set VALHEIM_INSTALL and BEPINEX_PATH as environment variables.

---

Packaging and Releases

Packaging and release automation are handled through .scripts/modtools.ps1 using the DW.ValheimModTools module:

• Create a release: pwsh ./.scripts/modtools.ps1 release (builds Release, creates the distribution archive, extracts changelog notes, syncs repository secrets, and creates a GitHub Release, Draft by default).
• Bump version and package: pwsh ./.scripts/modtools.ps1 package -Bump Patch
• Publish to mod portals: pwsh ./.scripts/modtools.ps1 publish -Target All (uploads to Thunderstore and Nexus Mods).

For full script options and secret configuration, see .scripts/README.md.
