A common point of confusion after activating the Create Immersive Aircrafts Resource Pack is finding that crafting tables still ask for the standard Immersive Aircrafts ingredients rather than Create gears and metal parts.
Resource Pack vs. Data Pack
In Minecraft, client-side resource packs can only alter visuals, sounds, and language text. Even though your aircraft parts, engines, and upgrades now look like Create components and carry renamed tooltips, the resource pack itself cannot modify crafting recipes.
Adding Recipe Support to a World
To actually build aircraft using Create mod materials, you must pair this resource pack with its separate companion data pack.
1. For a brand-new singleplayer world, click More on the world creation screen, select Data Packs, and move the companion recipe data pack into the Selected column before generating the world.
2. For an existing singleplayer world or multiplayer server, place the separate recipe data pack inside that specific world save's datapacks folder.
3. Run /reload in game if you have operator permissions, or close and reopen the world.
Once both packs are active together, your crafting recipes will require Create gears and metal parts that match the updated visuals.
