Black Metal Buildables

Black Metal Buildables is a small Valheim mod that adds black metal variants of vanilla iron building pieces.

The current implementation clones existing Valheim iron build-piece prefabs, changes their gameplay metadata, registers them in the Hammer build menu, and applies a lightweight runtime material tint so they read as black metal without custom meshes, textures, icons, or Unity asset bundles.

Current Pieces

Piece	New prefab	Source prefab	Cost
Black Metal Cage Floor 1x1	blackmetal_floor_1x1	iron_floor_1x1_v2	1x Black Metal
Black Metal Cage Floor	blackmetal_floor_2x2	iron_floor_2x2	2x Black Metal
Black Metal Gate	blackmetal_gate	iron_grate	2x Black Metal
Black Metal Cage Wall 1x1	blackmetal_wall_1x1	iron_wall_1x1	1x Black Metal
Black Metal Cage Wall 2x2	blackmetal_wall_2x2	iron_wall_2x2	2x Black Metal

All pieces are added to:

Piece table: Hammer
Category: HeavyBuild

AI USAGE

How I used AI:

1. Used to validate C# syntax
2. Used to generate documentation
3. Used to verify Jotunn, BepInEx, and Unity API
4. Generated icon
5. Assisted in using 3D modeling software a. Knew almost nothing about 3D modeling, so used it to get answers on how to accomplish tasks in the software (blender, unity) b. With it, I used open source materials and primitive items in blender & unity to create the Black Metal Corewood Reinforced assets from scratch i. To be ultra clear: I performed the work, with the AI teaching me how to use the software effectively

Build

From the repo root:

dotnet build .\src\BlackMetalBuildables.csproj

Build output:

Manual Install For Testing

This repo intentionally does not auto-deploy into a mod profile.

After building, copy:

src\bin\Debug\net472\BlackMetalBuildables.dll

into a BepInEx plugins folder. Then launch Valheim with that profile.
