Include Point Lights in Subdivision Controls whether point lights are used when shooting direct lights. If this switch is off, then point lights are not included in illumination calculated directly at vertices. Default=on. Include Linear Lights in Subdivision Controls whether linear lights are used when shooting direct lights. If this switch is off, then linear lights are not used in calculating the illumination at vertices. Default=on. Include Area Lights in Subdivision Controls whether area lights are used when shooting direct lights. If this switch is off, then area lights are not used in illumination calculated directly at vertices. Default=on. Include Skylight When turned on, skylight is used when shooting direct lights. If this switch is turned off, then skylight is not used in illumination calculated at vertices directly. Default=off. Include Self-Emitting Faces in Subdivision This switch controls how self-emitting faces are used when shooting direct lights. If this switch is turned off, then self-emitting faces are not used in illumination calculated at vertices directly. Default=off. Minimum Self-Emitting Size This is the minimum size that a self-emitting face will be subdivided when calculating its illumination. Minimum size is used rather than the number of samples to allow larger faces to be sampled more than smaller ones. Default=6.0. Light Painting Rollout (Radiosity) Rendering menu/main toolbar > Render Setup > Render Setup dialog > Choose Default Scanline Renderer as the active production renderer. > Advanced Lighting panel > Select Advanced Lighting rollout > Choose Radiosity from the drop-down list. > Light Painting rollout The light painting tools in this rollout allow you to touch up shadowed and illuminated areas manually. You can use these tools to touch up shadow and light-leak artifacts without having to do additional remodeling or radiosity processing. Using Pick Illumination, Add Illumination, and Remove Illumination, you can add or remove illumination on one selection set at a time. To use the light painting tools, you first select objects, and then choose a light painting tool: Pick Illumination, Add Illumination, or Remove Illumination. The active button is highlighted in yellow, and when it is over a selected object, the cursor changes to a crayon icon for the Add and Remove Illumination tools, or to an eyedropper icon for Pick Illumination. 6206 | Chapter 20 Rendering
