Gantry

Gantry imports industry-standard 3D formats, previews them in a RealityKit-powered viewport, and exports USDZ. Edit materials, optimize textures per channel, and ship in seconds.

Available on macOS, iOS, and iPadOS.

Getting Started

To open a 3D model, choose File → Open (⌘O), click the Import button in the toolbar, or drag and drop a file onto the Gantry window.

The window has three areas:

• Viewport (center): Interactive 3D preview rendered by RealityKit
• Inspector (right): Material editing, stage properties, and animation controls
• Toolbar: Import, export, environment picker, and inspector toggle

Quick Tips

Drag and Drop

Drag 3D files directly from Finder into Gantry to open them instantly. Supported formats are shown in the welcome screen.

Inspector

Press ⌘I to show or hide the inspector. It gives access to material editing, stage metadata, and animation controls.

Undo

Gantry uses a layer-based undo system. Press ⌘Z to remove the last edit layer and step back through your changes.
