Icon Forge - 3D Icon Renderer

Icon Forge is a Unity Editor tool for rendering crisp, transparent PNG icons directly from your 3D prefabs — no scene setup, no extra camera, no manual compositing.

Drop in your prefabs, frame each one with its own saved camera angle, and export with one click. Batch render your entire library, pack everything into a spritesheet, or generate a full turntable animation sheet for any prefab. Perfect for inventory icons, skill UI, item databases, and any project that needs consistent, high-quality 2D icons from 3D assets.

Key features:
Live checkerboard preview — transparent background, what you see is what you export
Per-prefab camera settings — angle, distance, projection mode, and focal point saved individually per object Camera orbit, pan, and zoom directly in the preview (drag / Cmd+drag / scroll)
Perspective and orthographic projection modes
Animation frame selection — pick any clip and scrub to the exact frame before rendering; works with both Animator and legacy Animation components
Turntable export — orbit the camera automatically and output a full rotation as a spritesheet grid
Spritesheet export — pack all prefabs into a single texture with configurable columns and padding
Auto sprite import setup — exported spritesheets and turntables are automatically configured as Sprite (Multiple) with named slices
Unlit rendering mode for flat, lighting-independent icons
Interactive directional light with color, intensity, and drag-to-rotate controls
Smart file naming with dynamic tags: [name], [index], [count], [resolution], [width], [height], [date], [timestamp], [preset]
File conflict resolution with "apply to all" for batch exports
Copy current render to clipboard (macOS and Windows)
Reorderable prefab list with drag-and-drop from the Project window
Full Undo/Redo support throughout
ScriptableObject-based presets — version-control friendly, shareable across your team

Works with Built-in, URP, and HDRP render pipelines
