Use this function to render the current viewport. If you are working with a four-panel view you can render each view in succession.
You can define the type of render and other options in the Render Settings … menu.
You can quit the rendering anytime by pressing the esc-key or clicking anywhere with the mouse.
Rendering in the viewport does not support all types of rendering (e.g., no QuickTime VR images or movies). Furthermore, certain post processing effects such as motion blur will not be displayed.
The render progress is displayed in the form of a blue bar at the lower left of your Cinema 4D interface.
