If you want to render a single frame (or a single frame of an animation), render it in Render View. Advantages include the following:

• easy to use
• Maya UI
• you can see the render as it occurs
• you can interrupt the render at any time
  NoteLarge scenes or image files may run out of memory. In this case, use batch rendering to reduce memory usage.

To render in Render View, see:

• Test render a low-res still or frame.
• Render a single frame.
