Global gates. Face strengths stay intact.
Preparing the card
Drag anywhere to turn and tilt / Tap to flipKeyboard: arrows rotate, Enter or Space flips, Escape resets.
Editing front; front is visible. Selection does not flip the card.
Freeze the card. Move the key light along a repeatable arc.
Default materials, fixed lights, optional effects off. View and background are retained.
Editing front / Crossing Streaks
Upload local images for the front face, or drop a file on a row. Files stay in this browser tab; switching preset or resetting settings discards uploads.

Fixed studio lighting. Each face keeps its own material settings. Diagnostics bypass beauty lighting and bloom.
Reference-derived optical model / front face
Optical relief is not bump height. Foil exposure is linear foil gain, not camera exposure or stops. Stars alter microstructure, not geometry or glints.
Reference spread: 0.014 (source JS: 0.013). Matching values do not imply identical lighting.
Three intersecting streak families with different slopes, spacing, and optical relief. Diagnostics show blended grating parameters at crossings.
Normal: /normal.png. Height: none. A missing input contributes no relief.
Positive: emboss. Negative: deboss. Zero: flat height contribution. Shading relief does not change the silhouette.
Metal mask: none (full face). White areas receive the metallic strength; black stays dielectric.
Off; enable in Effect layers. Stable, UV-anchored flakes inside foil coverage. Independent of diffraction.
Enabled. Applies to bright card highlights on both faces; bypassed in diagnostics.
