Vine Trellis

Guide Ovagro Vines through open space with modular trellis buildings.

Adds two new buildings that redirect vine growth without blocking movement or segmenting rooms:

• Vine Post — A 1×2 vertical trellis that guides vines upward. Press O to choose exit direction (left or right).
• Vine Rail — A 1×1 horizontal trellis that extends vine reach sideways. Chain multiple rails together for long horizontal runs.

• Build a Vine Post near an Ovagro Vine to redirect it vertically
• Chain Vine Rails from the Post’s top to guide the vine horizontally
• Vines automatically follow the trellis path
• Press O to flip direction on any trellis piece
• Buildings auto-snap to connect with adjacent trellis pieces

• Category: Utilities
• Research: Agriculture
• Materials: Any metal (25 kg for Rail, 75 kg for Post)
• Layer: Background — dupes walk through freely
• Buildings tint to match their construction material (copper looks copper, gold looks gold, etc.)
• Full thermal interaction — buildings absorb and release heat like normal buildings

• Works with base game, Spaced Out, and all DLCs
• Vine guidance features require the Prehistoric Planet Pack (Ovagro Vines are from that DLC)
• Without Prehistoric Planet Pack, buildings still place and look correct but won’t guide vines

• Mod by Esteban
• AI development assistance by Claude (Anthropic)
• Uses PLib[github.com] by Peter Han (MIT License)
• Built with Harmony 2.0[github.com] by Andreas Pardeike (MIT License)

• Vine shape may take a moment to update after placing/flipping trellis pieces
• Debug mode available in mod options (PLib) for testing — shows vine direction info

v1.1.0

• Added in-place material replacement — select the same building with a different metal and place it on top of an existing trellis to swap materials without deconstructing. Vines are preserved during the swap.
• Improved material tinting — buildings now use the material’s UI color for more vibrant and accurate tinting. Metals like Nickel Ore now show their distinctive color instead of appearing plain gray.
• Fixed cross-type replacement — Rails can no longer replace Posts (and vice versa). Only same-type material swaps are allowed.

v1.0.0

• Initial release — Vine Post and Vine Rail buildings with vine guidance, auto-snap, and material tinting.
