Interface

The window is split into three areas: the header, the sidebars and the viewport.

Header

• Left tabs — Outliner and Settings panels of the left sidebar.
• Right tabs — Materials and Properties panels of the right sidebar.
• Edge buttons — collapse or expand the corresponding sidebar.
• Help button — opens the built-in help window (also F1).

Sidebars

• Outliner — the scene hierarchy loaded from KOMPAS-3D. Click items to select objects; Delete removes the selected objects from Spectrum — the objects in KOMPAS-3D are not affected. Removed objects come back if you run the export again.
• Settings — rendering settings organized in tabs with quality presets. Changes are saved automatically.
• Materials — the material library with search, category filter and custom material files.
• Properties — properties of the currently selected object.

Viewport

The central area shows the 3D scene with an interactive preview. When exactly one object is selected, a transform gizmo appears on it (see Camera & Viewport).

Context menu

Right-click the viewport to open the context menu:

• Start/Stop rendering — turn rendering on or off. When rendering is off, the image does not react to camera moves or other changes.
• Load image for IBL — set an environment map for image-based lighting.
• Save rendered image — save the current render to a file.
• Clear scene — remove all objects from the scene.
