About this Mod

86+ integrated structure variants using blocks from Supplementaries and Amendments. A companion addon to Moog's Voyager Structures.
This mod works on Fabric, Forge and NeoForge.

MVSI is an addon for Moog's Voyager Structures that replaces its vanilla-block structures with versions that incorporate blocks from Supplementaries and Amendments. Once all the required mods are installed, the integrated variants load automatically in place of the standard ones. No configuration needed.
This is a data-only mod. No new items, no crafting recipes, no code. It just swaps in richer structure templates when the right mods are present.
Vision
The goal of MVSI is to integrate as many mods as possible into Moog's Voyager Structures. For each supported mod, we take the base MVS structures and revamp them using that mod's blocks and entities. When a structure spawns in your world, MVSI uses template pools to randomly choose between the available integrated variants based on which mods you have installed, so the more mods you run, the more variety you get.
Currently only Supplementaries and Amendments are supported, so both are required. In the future we plan to expand support to many more mods, and no single mod will be required. MVSI will simply enhance structures with whatever compatible mods are present.
