Render Scene dialog > Preset drop-down list (on the bottom row of controls)
Preset rendering options are available from the Rendering Presets drop-down list, which appears at the bottom of the Render Scene dialog. Some of the presets are tailored for relatively quick, preview renderings; others are for slower but higher quality renderings. Presets are saved as RPS files.
In addition to the default presets that ship with Autodesk VIZ, you can also create your own settings. At the bottom of the preset list, two choices let you create your own custom presets:
Load Preset—When you choose Load Preset, Autodesk VIZ displays a file selector dialog that lets you choose the RPS file to load.

Each category corresponds to one panel of the Render Scene dialog. Choose which panel's settings you want to load from the RPS file, and click Load. Once you load a custom preset file, its name appears on the drop-down list, along with the default choices.
Important: Even though the renderer is assigned in the Common panel of the Render Scene dialog, renderer assignments are not loaded with the Common category in the RPS file. The current renderer assignment has its own category in the Select Preset Categories dialog. For example, if the current renderer is the Default Scanline Renderer, the Select Preset Categories dialog will have a category labeled Default Scanline Renderer.
Save Preset—When you choose Save Preset, Autodesk VIZ first displays a file selector dialog, letting you name the RPS file. After that, the Select Preset Categories dialog opens.
Each category corresponds to one panel of the Render Scene dialog. Choose which panel's settings you want to save, and then click Save. Once you save a custom preset file, its name appears on the drop-down list, along with the default choices.

The RPS files that provide the default presets are in the \renderpresets subfolder of your \VIZ2008 folder. We recommend you save your own presets in this subfolder as well. If you choose a different location, Autodesk VIZ saves the full path name. (You can also use the Configure Paths dialog > General panel to specify your custom location.)
