Nine concrete problems
in 3D handoff to Apple platforms.
Most pipeline issues aren't subtle. They're the same nine things, every time. This is the companion to the launch video series — one section per feature, deep-linkable so a thread, DM, or pitch can land on the exact one being discussed.
Convert FBX, glTF, OBJ, STL, PLY → USD
Industry-standard 3D files do not always land cleanly in an Apple-platform OpenUSD pipeline. Your DCC tool exports one shape; your destination needs another.
Drop the file in. Gantry converts geometry, materials, and textures to USD, USDA, USDC, or USDZ, and shows you the result before you ship.
Preview natively
Most converters preview in a generic engine, so you only find out how a model looks on Apple platforms later.
Gantry's viewport is RealityKit, Apple's own 3D framework. Orbit, pan, and inspect the model before it leaves the app.
Light the scene
PBR materials look different under different lighting. You need to evaluate them under real conditions before shipping.
Pick from a curated set of image-based lighting environments. Adjust exposure and rotation. Show the environment as the background.
Edit materials
Imported materials rarely match the source. You need to adjust without round-tripping back to a DCC tool.
Tweak per channel: Base Color, Metallic, Roughness, Emissive, Opacity. Replace or clear individual textures. Changes update live in the viewport.
Switch variants
Same model, different looks — day/night, color options, configurations. You need to check every one before you ship.
Switch USD variants right in the viewport and review each look in RealityKit.
Export USD
USD has flavors — text, binary, crate, zipped packages, flat files, layered stages. Most tools pick one and do not tell you what changed.
Save as USD, USDA, USDC, or USDZ, and pick the flavor yourself. A USDZ export packages the model and its textures into one portable file.
Open in AR Quick Look
Converting is half the work. Seeing the asset in AR Quick Look is the other half, and most tools force you to re-share files to get there.
One tap from Gantry to AR Quick Look. See the asset in your room before it leaves your iPhone.
Minimal interface
Most 3D tools throw 200 controls at you. The work disappears in the interface.
The viewport is the room. Tools surface when you need them. The model is what you see.
Play animations
A static preview tells you nothing about motion. You need to see the animation before shipping.
Gantry plays embedded animation in the viewport. Play, pause, or stop it and check the motion before you ship.
