Expressions and export

Previewing expressions

The Expressions tab exposes all 51 ARKit shapes the head was built with, grouped by brow, cheek, eye, jaw, mouth, and nose. Drag a slider and the head updates live in the viewport. Nothing here is saved; it's a preview, not part of the double's own data.

Drive from video analyzes a video frame by frame for a face and plays its expressions back onto the head, with a scrub bar to move through it manually. It's a fast way to check that a set of shapes reads correctly on the model before you rely on them in an engine downstream.

Exporting

Export GLB writes the fitted head as a GLB file: the head geometry, all 51 expression shapes wired as morph targets by name, the baked texture if one exists (a flat color if not), and eyes matching whatever mode you've set on the Texture tab. Per-eye offset and scale adjustments are baked into the exported geometry too, so the file matches what you were previewing.

The export lands in the project's generated assets, ready to bring into a character rig or a game engine.
