Here at Structure Studios, we built our reputation by developing award-winning 3D/AR/VR software that changed how an entire industry does business. Now, we’re adding an AI-powered layer to our software that will make our 3D renders more realistic, efficient, and compelling:

Phase 1: Use Image Gen AI to transform basic 3D renders into stunning, photo-ready images; create a back-end pipeline to generate seamless PBR materials with AI.

Phase 2: Use our pre-existing unique software architecture to feed AI the data it needs (provided by our software team in the format required) to generate smart AI-assisted landscapes, AI geometry, and AI tools.

We deliver high-quality software our customers can rely on because we use the latest tech to create stable, maintainable code and because our deliberately small team of senior developers (no junior developers) is fast, agile, and highly productive.
