Main toolbar > Quick Render flyout

The Quick Render flyout lets you choose among these buttons:

The Quick Render buttons let you render the scene using the settings without displaying the Render Scene dialog. Choosing one of these buttons also changes which rendering settings are active in the Render Scene dialog.

By default, all the rendering options use the default scanline renderer. You can change the renderer assigned to Production or ActiveShade by using the Assign Renderer rollout on the Render Scene dialog > Common panel.
