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 Multi-Passes). 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.
