Flattenheim

Flattenheim is a lightweight Valheim terrain-building mod focused on fast, precise terrain shaping without Jotunn.

Re-upload and original authorship

This package is a community re-upload of the original Flattenheim mod by Heimlife, originally released as version 1.0.0. The original feature set is preserved. This release adds native, optional Dig Deeper compatibility directly in Flattenheim.dll. The original mod was authored by Heimlife.

Version 1.0.2 also fixes terrain tears when a flattening boundary ends exactly on a terrain-sector wall or corner.

Dig Deeper compatibility

When Dig Deeper is installed, Flattenheim's Pickaxe Flattening and Ramp terrain edits use Dig Deeper's live MaximumDepth and MaximumHeight settings. Dig Deeper is optional and is not a package dependency. If it is absent or its settings cannot be read, Flattenheim retains its original ±8 terrain-delta limit. No separate compatibility plugin is needed.

Features

Pickaxe Flattening

With a pickaxe equipped, hold the configured Flatten Hold key to flatten terrain around the target area.

Config:

• Size: 1–20 m
• Hardness / Smoothness: 0–100
• Shape: Square / Circle
• Ground Texture: Dirt / Keep Existing
• Flatten Hold: remappable hotkey

Flattenheim uses direct terrain editing rather than spawning permanent build pieces.

8-Direction Grid Movement

Optional world-grid movement while flattening.

Movement snaps to:

• N
• NE
• E
• SE
• S
• SW
• W
• NW

This is independent of camera direction.

Hoe & Cultivator Radius

Adjust the effective terrain-operation radius of the Hoe and Cultivator.

Config:

• Enabled
• Hoe Radius
• Cultivator Radius
• Increase Radius hotkey
• Decrease Radius hotkey

The mod keeps separate radius values for the Hoe and Cultivator.

Ramp Tool

Adds a Ramp option directly to the Hoe build menu.

Behavior:

• Creates a straight terrain ramp from the player's current ground position to the aimed terrain point
• Uses a persistent live trajectory preview
• Ramp start updates with the player's current position
• Ramp end updates with the current cursor/aim point
• No permanent build object is placed
• Uses direct terrain editing

Config:

• Ramp Thickness: 1–20 m

Revert Original Terrain

Adds Revert Original Terrain directly to the Hoe menu.

Behavior:

• Shows a live radius around the aimed terrain point
• Restores terrain height modifications inside the selected area
• Resets modified terrain paint in the affected area

Config:

• Radius: 1–20 m

No Jotunn

Flattenheim only requires:

• BepInEx
• Harmony
