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 (page
3–2). Some of the presets are tailored for relatively
quick, preview renderings; others are for slower

as RPS files.

you quickly switch between active presets.
In addition to the default presets that ship with
3ds Max, you can also c reate your own settings. At
