Vivillon Overhaul (Cobblemon)

Vivillon Overhaul

Massively reworks Vivillon and its pre-evolutions to properly reflect the games with how they evolve, aswell as fixing many key issues like getting multiple different Vivillon patterns in one biome, not being able to read Vivillons unique dex entries, Scatterbug not being able to spawn in forest biomes with tall trees, and more! Comprehensive list of changes are located in the changelog.

Compatibility

Currently only has explicit support for Terralith, WWEE, BOP, BWG, Nature's Spirit, and more (full list in changelog), aswell as vanilla biomes, Vivillon and its pre-evolutions will only spawn in biomes with explicit support.

Can I install this on my current world?

Yes, but your current Scatterbugs and Spewpas will only be able to evolve into the Meadow pattern Vivillon.
