Unbound grafts a real-time AI onto its SDF sculpt engine

Unbound Technologies launches Unbound Loop, a web tool combining SDF 3D sculpting with a real-time image-to-image AI engine for game developers.

Unbound Technologies extends its 3D modeling tool to real-time AI with Unbound Loop, a web application for game developers and 3D printing enthusiasts. The core principle is based on a clear promise: AI enriches the artist's work without ever replacing it.

For modeling, users sculpt from simple volumetric shapes using SDF (signed distance fields), an approach that frees them from mesh topology: you place, combine, and carve. On top of this, an image-to-image engine runs in real-time, up to 40 Hz, detailing the render on the fly. Two sliders remain in the user's hands, adjusted independently: the influence of AI on one side, and fidelity to the sculpted shapes on the other, which distinguishes the tool from simple prompt-based generation. The result can be exported as meshes ready for game engines and 3D printing, in glTF, GLB, STL, or 3MF formats.

Unbound is not a newcomer: the company has been developing a desktop 3D engine based on SDFs for years, popular with independent studios, and its team boasts over twenty years of experience in computer graphics and creative tools. Loop is its web version, built upon this foundation.

The trial is free and requires no credit card, with one important caveat: renders produced in the free version fall under a CC BY 4.0 license, requiring attribution, and are used to train Unbound's models. Paid plans remove attribution, guarantee full commercial ownership, and exclude data from training.
