Where it started.

An idea for a game character should be able to start with a pen. Vec, developed as Trazo, turns a photographed sketch into an editable asset from an Android phone. It is built around creating the bubble-tea cups in Bubble Tea Cats.

From idea to implementation.

Photograph a drawing, generate the artwork and refine it on your phone. The app separates the body, liquid and tube masks, with editable firing points and directions. A connected Mac handles generation and processing, then saves versioned assets into the game project.

Start on paper. Keep creating on your phone.

A camera photo or an image from the phone starts the generation. The mobile editor lets you inspect each layer, paint or erase masks, zoom with two fingers, undo and adjust the points where the cup fires. Those edits rebuild the assets without another AI generation.

More than a finished-looking image.

The pipeline produces transparent body artwork, separate material masks, shading layers and editable anchor data. PNGs use a shared 256 × 320 canvas; SVG geometry uses 128 × 160 units. Versioned files go into the Bubble Tea Cats project so its importer can prepare them for the game.

A connected production workflow.

The phone provides the creative interface; the Mac performs generation and processing. Saved revisions, recoverable uploads and local pending edits help preserve work when the connection drops. The app reports actual processing stages instead of inventing a generation percentage.

Where it stands.

A working private Android application. Generation runs on a connected Mac, not on the phone. The example uses a real source sketch and its generated result; inspection colours are replaced by the materials selected in the game. Saved assets still pass through the game’s importer and review before use.
