About Spectrum
Spectrum turns KOMPAS-3D assemblies into photorealistic images in minutes. It connects to your CAD environment with a single file, renders in real time on your GPU, and requires no visualization expertise — what you see in the viewport is what you get in the final image. It uses real-time GPU ray tracing and a MaterialX-based material library, allowing you to assign accurate materials, add HDR environments, and render without complex setup.
How it works
Connect the plugin — unpack the archive and enable spectrum.kompas3d.rtw via the Applications menu in KOMPAS-3D. No installer needed.
Export your assembly — one click, and the scene appears in Spectrum automatically.
Apply materials and save — pick materials from the library, add HDR lighting, save the finished image.
Availability
Free to download and use trial version with limited image quality, Windows 10/11, fully portable. Rendering works offline — an internet connection is only needed to load the built-in material library.
