Use the following parameters to define advanced render settings. (See Defining a Custom Render Quality.) In general, increasing (or turning on) any one of these settings increases the quality of the rendered image. However, it also increases the time required to generate the image. Increasing the values of multiple settings may increase render time exponentially. See Rendering Best Practices.
| Setting | Description |
|---|---|
| General Options | |
| Image Precision (Antialiasing) | Increase this value to smooth jagged edges in the rendered image. Enter a value between 1 (most jagged) and 10 (smoothest). See Render Performance and Image Size/Quality. |
| Reflection and Transparency Options | |
| Maximum Number of Reflections | Increase this value when objects are missing from reflections in the rendered image. Enter a value between 0 (no reflections) and 100 (most reflections). See How Refractions and Reflections Affect Render Performance. |
| Maximum Number of Refractions | Increase this value when you cannot see objects through multiple panes of glass. Enter a value between 0 (completely opaque) and 100 (completely transparent). See How Refractions and Reflections Affect Render Performance. |
| Blurred Reflections Precision | Increase this value when the edges or surfaces of objects in blurred reflections are speckled. Enter a value between 1 (speckled) and 11 (smoothest). |
| Blurred Refractions Precision | Increase this value when the edges of objects seen through rough glass are speckled. Enter a value between 1 (speckled) and 11 (smoothest). |
| Shadow Options | |
| Enable Soft Shadows | Select this option to make shadow edges blurred. Clear it to make shadow edges sharp and distinct. See GUID-9EBC105D-315F-446A-8EFE-91FBBE72FC99.htm#WS1A9193826455F5FF-29C43AA61173633F416-629C. |
| Soft Shadow Precision | Increase this value when the edges of soft shadows are speckled instead of smooth. Enter a value between 1 (speckled shadows) and 10 (smoothest shadows). |
| Indirect Illumination Options | |
| Compute Indirect and Sky Illumination | Select this option to include light from the sky and light that bounces off other objects. Clear it to omit these light sources from the rendered image. See GUID-9EBC105D-315F-446A-8EFE-91FBBE72FC99.htm#WS1A9193826455F5FF-29C43AA61173633F416-629A. |
| Indirect Illumination Precision | Increase this value to achieve more detailed indirect illumination (the level of detail that is visible in indirect light) and shadows. Greater precision yields smaller subtle effects, usually in corners or below objects. Enter a value between 1 (less detail) and 10 (more detail). |
| Indirect Illumination Smoothness | Increase this value when indirect illumination looks splotchy or scaly. Greater precision yields smaller subtle effects, usually in corners or below objects. Enter a value between 1 (most splotchy) and 10 (least splotchy). |
| Indirect Illumination Bounces | Increase this value when areas of the scene that should be indirectly illuminated do not display as desired. This setting determines the number of times that indirect light bounces off objects in the scene. It controls the amount of realism in indirect lighting. With more bounces, light can penetrate further into a scene, resulting in more physically correct lighting and a brighter scene. Enter a value between 1 (less indirect illumination) and 100 (most indirect illumination). Typically, 3 bounces achieve sufficient results for indirect illumination. Further bounces can add more subtle effects, but they are often not significant. |
| Daylight Portal Options (only applies to sunlit interiors): These settings are available only for interior views that include daylight. See Daylight Portals. | |
| Windows | Whether the rendering engine calculates daylight portals for windows. By default, this setting is turned off. |
| Doors | Whether the rendering engine calculates daylight portals for doors that contain glass. By default, this setting is turned off. |
| Curtain Walls | Whether the rendering engine calculates daylight portals for curtain walls. By default, this setting is turned off. |
