Rendering shades the scene's geometry using the lighting you've set up, the materials you've applied, and environment settings, such as background and atmosphere. You use the Render Setup dialog to render images and animations and save them to files. The rendered output appears in the Rendered Frame Window, where you can also render and do some setup.

Rendering "fills in" geometry with color, shadow, lighting effects, and so on.

Cameras
Cameras frame the scene, providing a controllable point of view. You can animate camera movement. Cameras can simulate some aspects of real-world photography, such as depth-of-field and motion blur.
Environments and Rendering Effects
A variety of special effects, such as film grain, depth of field, and lens simulations, are available as rendering effects. Another set of effects, such as fog, are provided as environment effects.
Environment settings let you choose a background color or image, or choose an ambient color value for when you render without using radiosity. One category of environment settings is the exposure controls, which adjust light levels for display on a monitor.
Rendered Image Effects provide a way for you to add blur or film grain to a rendering, or to adjust its color balance.
Object-Level Rendering Controls
You can control rendering behavior at the object level.
Materials
Only materials compatible with the selected renderer will work as expected in your final rendered output. To see a list of materials compatible with the currently selected renderer, open the Slate Material Editor. With default 3ds Max settings, the Material/Map browser in the Slate Material Editor will only list compatible materials. These default settings include having Show Incompatible set to off, found in the Material/Map browser options menu, and the Material Editor locked, found in Assign Renderer within the Render Setup dialog.
