Designer mode supports three preview-only layers that help customers visualize the final product. None of these are included in print-ready exports — they appear only while editing or when the customer toggles Preview on the storefront. Configure them in Calculator Editor → Designer (Step 5) → Canvas bindings in Designer mode.
Scene (productOverlay) frames the artboard inside a product mockup using a nine-slice image (corners and edges stretch, center stays open for the design).
| Setup | How |
|---|---|
| One scene for everyone | Add Scene binding → fixed image URL → upload a PNG frame with a transparent center hole. |
| Scene per choice | Add Scene binding → map each swatch or dropdown value to a different frame image. |
Scenes are for visual context only — they do not appear on proof PNGs, print files, or cut-line SVGs.
Preview Effect (previewOverlay) adds a finish layer over the design when Preview mode is active — laminate gloss, matte haze, holographic glitter, and similar looks.
Built-in finishes include Glossy, Mirror, Matte, Cracked Ice, Glitter, Pixie Dust, and Prismatic. Map a material swatch or dropdown to a built-in finish, or upload a custom overlay image with blend mode and opacity.
| Setup | How |
|---|---|
| One finish | Add Preview Effect → fixed built-in material or custom image. |
| Finish per choice | Map each material or laminate option to a different finish. |
| Multiple options | Add several mapped sources — the first option with a matching value wins. |
Customers see the effect when they click the Preview tool on the canvas (Designer mode only). The tool is hidden when Customer access is Product preview because the whole editor is already a live preview.
For clear vinyl stickers, set the Background binding's per-choice image mode to Transparent on the swatch that represents clear material. The canvas shows a checkerboard behind the artwork and Preview mode draws a cut-edge outline so customers see how the sticker reads on clear stock.
Pair transparent background with a Cut line shape binding (preset shape or Auto (die-cut)) and enable Export cut-line SVG under export settings.
