A free, Open-Source 3D Viewer designed to make it all easier.

Download (v1.1, Windows 32 & 64 Bit)

Installer-less version (ZIP, Windows 32 or 64 Bit)

Massive 3D Format support

Free and powerful 3D Viewer for more than 40 file formats, including OBJ, 3DS, BLEND, STL, FBX, DXF, LWO, LWS, MD5, MD3, MD2, NDO, X, IFC and Collada.

Flexible User Interface

Tabbed User Experience so multiple scenes can be open at the same time. 3D views are split in up to four viewports. Different camera modes (orbit, FPS or axis-aligned) are available for each viewport. New files are loaded in the background.

Edit & Fix

Common glitches such as inproper normal vectors, flipped UV coordinates (or textures) or degenerate geometry can be fixed directly in open3mod. No need to fire up a fully-fleshed 3D suite.


Export scenes, parts of scenes and textures to a multitude of destination formats, including OBJ, PLY, 3DS, Collada and STL.

Skeletal Animation

Plays even complex skeletal animations. Individual frames can be locked, playback speed is adjustible and scene transformations can be inspected anytime.

Hierarchy Inspector

Deep looks into the scene hierarchy, targeting 3D developers who need to integrate 3D scenes into their engines.
