Setting Up Dense Architectural Inertia

Installation and Setup

Dense Architectural Inertia adjusts Create copycat block weights to work correctly with Valkyrien Skies physics. Add the data pack to your world's datapacks folder, then fully restart your game client so the physics engine recognizes the new mass values.

Once loaded, copycat blocks will weigh according to their actual dimensions and materials, matching their full-block counterparts. This prevents flying contraptions from behaving unrealistically—thin panels won't feel weightless, and decorative blocks won't cause unexpected balance issues.

The data pack supports standard Create copycats, Create: Connected variants, and blocks from Create: Copycats+. Build your airships and moving vessels normally; the adjusted physics will apply automatically to all compatible copycat blocks.
