Create: Aeronautics Weightworks is a compatibility addon that rebalances the mass of Copycat blocks for Create: Aeronautics.
Most Copycat blocks are assigned a mass of 0.01kpg, allowing builders to use decorative and functional Copycat blocks without significantly increasing the weight of their airships. This helps reduce unnecessary mass while maintaining compatibility with Create: Aeronautics' physics system.
Features Sets most Copycats blocks to a mass of 0.01kpg Improves compatibility between Copycats and Create: Aeronautics Reduces airship weight from decorative blocks Lightweight and server-friendly Perfect for builders who use large amounts of Copycats blocks Why? By default, some Copycats blocks can contribute more mass than desired. Weightworks standardizes their mass values, making airship weight calculations more predictable and builder-friendly.
Build bigger. Fly lighter. ⚙️🚀
