Getting Started
Requirements, add-in installation and your first photorealistic render of a KOMPAS-3D assembly.
Spectrum is a photorealistic rendering application built on AMD Radeon ProRender. It takes scenes from KOMPAS-3D, performs ray tracing and renders the result in real time, letting you apply materials to models and create photorealistic images.
System Requirements
- OS — Windows 10/11, 64-bit.
- GPU — virtually any modern card works: AMD, NVIDIA or Intel. A card with hardware ray tracing (GeForce RTX, Radeon RX 6000 or newer) is recommended for a smoothly interactive viewport.
- Internet — not needed for rendering; the connection is only used to load the built-in AMD GPUOpen material library.
Installation
- Unpack the distribution. Extract
spectrum_vX.Y.zipto any folder — there is no installer. Use a directory with user write access (eg.C:\Users\user) to avoid errors while the app is running. - Connect the add-in in KOMPAS-3D. Open the Applications menu. Point it to
spectrum.kompas3d.rtwfrom the unpacked folder — the plugin ships as this single file. - Launch Spectrum. Run
spectrum.exe. Spectrum must already be running when you export from KOMPAS-3D.
Your first render
- Send a model from KOMPAS-3D. Use the Spectrum plugin in KOMPAS-3D to export the current assembly. The scene appears in Spectrum automatically.
- Frame the view. Rotate and pan the camera in the viewport until the model is positioned the way you want it (see Camera & Viewport).
- Assign materials. Open the Materials tab, pick a material from the library and apply it to the selected objects (see Materials).
- Save the result. Use the button in the left side menu or choose Save rendered image from the context menu of the render area.
