3DBrowser Pro R17 from Mootools is a desktop application for managing, visualizing and optimizing 3D content through a dedicated file explorer, a scene viewer and an image viewer. It reads most image formats and many 3D formats, including 3ds Max, Maya (via provided plugins), FBX, GLTF/GLTB, USD, E57 point clouds, Blender 3 and 4, SketchUp, Cinema 4D, Collada and STL.
The viewer handles textures, vertex colours and user normals, and works with 3DBrowser and Windows file explorer to generate preview thumbnails you control, setting a viewpoint and display mode per file, directory or format. Rendering incorporates normal maps and ambient occlusion, and display modes include vignetting, mirroring, shadows, AO/NMAP/Wireframe and cutaway views in the Pro version. Navigation covers targeted zoom, orbital rotation, airplane mode and fast recentering with saved viewpoints.
3DBrowser Pro adds Polygon Cruncher, which reduces polygon counts while keeping detail, textures, vertex colours and normals, with MagicCruncher setting each object's optimization automatically. Version 17.20 brings improved USD/USDZ handling, scene merging, a 3ds Max 2026 plugin, 4K monitor support, multiple tabs and split view.
