AseVoxel - Aseprite Voxel 3D model and preview
A downloadable Aseprite Extension
AseVoxel
Realtime voxel preview, flexible rotation systems, animation tools & direct export inside Aseprite
What Is It?
AseVoxel transforms your layered Aseprite files into lightweight 3D voxel scenes. Each visible non-group layer becomes a Z-slice, and each opaque pixel becomes a voxel. The tool provides a live 3D preview, multiple rotation paradigms, adaptive redraw throttling, animation capture, and direct OBJ/PLY/STL export — all without leaving Aseprite.
• Live Preview
• Adaptive Render Throttle
• Euler / Absolute / Relative Rotation Systems
• Trackball & Orbit Controls
• Animation Frame Generator
• Export to OBJ / PLY / STL
• Lighting and shading Modes
• Optional Remote Renderer Server (soon)
Key Features
Layer → Voxel Mapping
Intuitive depth: top layers become the front, hidden or group layers are ignored.
Three Rotation Systems
Euler: direct angles & matrix math.
Absolute: spins the model through its fixed axes.
Relative: camera pitch/yaw/roll.
Trackball / Orbit Input
Middle drag for free rotation, plus instant presets for front/top/iso views.
Adaptive Interaction
Median render time adjusts sampling interval automatically, keeping motion smooth on both fast and potato PCs.
Animation Generator
Create frame stacks or GIF workflows by rotating around an axis with configurable step counts.
Export Pipeline
OBJ with colors & materials, PLY with vertex colors, or STL for solid triangulation.
Outline & Contrast
Automatic background contrast, outline modes, and pattern-based edge highlighting.
Modeling Mode
Inspect per-slice voxels with visibility toggles; optionally hand off preview to a remote WebSocket renderer.
How To Use
Meet my dad, this is Alfredo:

Alfredo is just an Aseprite file. He has multiple layers — each one becomes a voxel slice:

Alfredo’s size: 13 × 16 pixels per layer, across 14 layers. That means his voxel volume is 13 × 16 × 14.
Things You Can Do With Alfredo
Preview
Go to Edit → AseVoxel Viewer.
Two windows open:
• A live 3D preview (default isometric view)
• An info dialog with tabs and controls
Rotate freely with middle-click drag:

Rotate & Scale
In the info dialog, press “Open Controls Dialog” to adjust:
- 3 Rotation Modes:
- Euler: full rotation matrices (perfect for reproducible setups).
- Absolute: model-space spins, like rotating a cube on fixed rings.
- Relative: intuitive camera orbit (pitch/yaw/roll).
- Scale sliders
- Quick View buttons (Front, Top, Side, Iso)
- Perspective vs Orthogonal toggle (future feature)
Model and Edit
In the info dialog, go to “Model” tab to find:
- 4 90° Transform Rotation Buttons
- Layer Scroll Mode
