Schematician's Goggles
by MementoMori
Schematician's Goggles is a NeoForge utility mod for 1.21.1 that turns the view through the goggles into a contraption diagram with live physics overlays.
What it does
Once the goggles are worn, the world is redrawn as a contraption diagram. An in-world physics overlay shows forces on a sublevel, including center of mass and live force vectors for lift, drag, thrust and gravity. The overlay is gated behind the wearable item, so nothing appears until the goggles are equipped.
The mod builds on Aviator's Goggles and keeps its heads-up display, showing stress, burner output and similar readouts. Its recipe is kept simple enough to craft early, and the mod requires Create Aeronautics on both sides. Schematician's Goggles is open source under the MIT License and is published for NeoForge only, for 1.21.1, with the 0.10.0 file as the latest build from 2026-07-13.
Key features
Contraption diagram view
Equipping the goggles switches the world view to a contraption diagram that outlines the structures on screen.
Live force vectors
While the goggles are worn, each sublevel displays its balance point and arrows for lift, drag, thrust and gravity, updating as it moves.
Aviator's Goggles HUD
The stress, burner output and other readouts from Aviator's Goggles stay on the heads-up display.
Simple crafting recipe
The goggles use a recipe simple enough to make early, following the pattern of Aviator's Goggles.

Use cases
Inspecting flying contraptions

Who it’s for: Players who build with Create Aeronautics contraptions and want force readouts while they work, and server owners who want the overlay available on a shared world.
How it compares
Create Aeronautics x Curios API Compat is a NeoForge compatibility mod for 1.21.1 under All rights reserved, not open source, and it must run on both sides. AeroWear is also NeoForge, client and server, with files for 1.21.1 – 26.1.2 and no open source license. Create: Goggles in Creative is open source under the MIT License and runs on the client alone, so servers do not need it, while Create: Goggles Plus is open source under the MIT License and runs on client and server.
