Pixelplan - PIXELPLAN O4C Viewer (O4CViewer.exe). This simple little tool was originally designed to be used in conjunction with other PixelPlan software...
Pixelplan O4C Viewer lets you open and display many types of 3D object files with ease. Originally built to work with PixelPlan O4C signed models and virtual 3D walks, it now supports a wide range of formats like 3DS, DAE (Collada), MDL, OBJ, B3D, DXF with textures, VRML, and WRL. You can also load models and textures directly from ZIP archives — a convenient way to preview 3D assets without extracting them.
Designed to be simple and beginner-friendly, this fast 3D object viewer focuses on smooth navigation, zooming, and model inspection. Though advanced tools are minimal, the app includes dynamic lighting with bump-mapping and shadowing for top-class display quality, ideal for artists checking game assets, open-world anime gacha models, or 3D printing designs.
Free, lightweight, and easy to use, Pixelplan O4C Viewer is a great choice for anyone who needs a quick solution for viewing 3D object files across projects, including indie game development and VR model previewing.
