002 · WHY GANTRY

Shipping 3D to Apple platforms still starts with a converter.

Gantry is built for that job.

003 · FEATURES
01

REALITYKIT
VIEWPORT

Orbit, pan, and inspect in a real-time RealityKit viewport before you export. Switch USD variants. Play, pause, or stop embedded animation in place.

ENVIRONMENT
LIGHTING

Curated image-based lighting environments. Adjust exposure and rotation, or show the environment as the background. Check materials under different light before you ship.
