Icon Studio²

Icon Studio is an Editor tool that renders production-ready game icons from any

prefab or scene object — without touching your scene, adding a camera rig, or

writing a line of setup code. Open the window, drop in your prefab, and you have

a fully lit 3D preview and a one-click PNG export path in seconds.

─ LIVE 3D VIEWPORT:

The right-hand viewport updates in real time as you adjust every setting. Orbit

the camera with a left-click drag, independently orbit the key light with a

right-click drag, and scroll to zoom. Corner bracket indicators show you the

exact export boundary so there are no surprises in the final image.

─ FLEXIBLE OUTPUT: 

Three capture modes cover the full range of use cases:

  • Opaque — exports with a solid background colour of your choice.

  • Transparent — removes the background and preserves the object's silhouette

    in the PNG alpha channel, ready to drop onto any UI background.

  • Solid Color — floods the silhouette with a flat tint; ideal for shadow

    icons, selection highlights, or stylised key art.

Output sizes: 256 × 256 up to 4096 × 4096, all square. Every exported file is

automatically imported into the project with Alpha Is Transparency enabled.

─ OVERLAY SYSTEM:

Layer images and text directly onto the icon without leaving the tool:

•  Background Image — composite a gradient, painting, or photo behind the 3D render.
•  Foreground Image — place brush strokes, frames, grunge, or any 2D art in front of the object. Supports position, rotation, and scale controls with full alpha blending.
•  Text Overlay — bake a label, item name, or level number onto the icon. Choose font, size, colour, anchor point, and pixel offset. Font size is defined at a 512 px reference canvas so text remains visually consistent at every export resolution.

─ BATCH GENERATION: 

Point Icon Studio at a folder of prefabs, load them into the batch list, and export

an entire icon set in one operation. All three capture modes (opaque, transparent,

and solid colour) are available for batch runs. The same lighting and overlay

settings are applied to every prefab in the batch.

─ NON-DESTRUCTIVE:

Icon Studio runs entirely inside Unity's built-in PreviewRenderUtility. Your scene,

lighting, and camera are untouched. The tool's state (rotation, lighting, overlays,

output path) is saved automatically between sessions and survives domain reloads.
