CONVERSION
In: GLB, glTF, FBX, OBJ, STL, PLY.
Out: USDZ, USD, USDC, USDA.
Preserve composition—references, variants, animation, your edits—or flatten to one self-contained file for AR Quick Look and visionOS.
VIEWPORT
Real-time RealityKit preview. Orbit, pan, and inspect—exactly as they render on Apple platforms. Play, pause, and reset animation in place.
LIGHTING
Curated IBL environments: Neutral, Beach Sunset, Downtown Night, Rooftop Sunny, and more. Exposure, rotation, reflections. Use any as the background.
MATERIALS
Edit per scene, live. Keep them as authored, or convert to USD Preview Surface or MaterialX. Base Color, Metallic, Roughness, Emissive, and Opacity. Swap or clear textures per channel.
TEXTURES
Control file size per channel. JPEG, PNG, AVIF. Quality, resolution, mipmaps.
What you see is what you export.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
- Improved export flow
Save to any USD format — .usd, .usdc, .usda, or .usdz — and your scene comes out exactly as you built it: references, variants, animation, and every material edit preserved. Nothing gets flattened or dropped.
- Smoother exporting
Exporting large scenes no longer freezes the app — keep working while it saves.
- Play/Pause/Reset your animations.
New play, pause, and stop/reset controls preview embedded animation right in the viewport.
- Faster material editing
Change colors and material inputs and see the result update instantly and reliably.
- Open more, more easily.
Import FBX, glTF, OBJ, STL, and PLY, drag files straight into the window, and let Gantry handle companion files and folders for you.

Correct model orientation and grounding, an accurate scale indicator, refined lighting and environment previews, and inspector polish.

Lots of stability fixes, including smoother opening of files from outside the app.
