The default mode is *Fragment Lighting* which perform all light shading in the fragment shader porsion of the graphics pipeline. In this case all both image based lighting as well as any punctual lights are used to shade the material. The other case *No Lighting* which ignores all light sources in the scene and the material is rendered without shading. This mode can be useful with models that should not be shaded, for example tools (gizmos) inside of a 3D editor. ` } ComboBox { id: lightingComboBox textRole: "text" valueRole: "value" implicitContentWidthPolicy: ComboBox.WidestText onActivated: rootView.targetMaterial.lighting = currentValue Component.onCompleted: currentIndex = indexOfValue(rootView.targetMaterial.lighting) model: [ { value: PrincipledMaterial.NoLighting, text: "No Lighting"}, { value: PrincipledMaterial.FragmentLighting, text: "Fragment Lighting"} ] } VerticalSectionSeparator {} MarkdownLabel { text: `## Non Triangle Primitive Sizes Generally if you use the Mesh file format baked by balsam, or the runtime loader for loading glTF2 scenes, the geometry primitive will be individual triangles, so these properties are not useful.
