How to Use Clipping Planes in Maya
Every camera has a set of clipping planes. They determine how close and how far an object can be from the camera and still be rendered. The default settings for the Near Clip Plane and Far Clip Plane are 0.10 units and 10,000 units, respectively. In other words, if an object were closer than 0.10 units or further than 10,000 units from the camera, it would not be rendered.
You may need to alter this setting if you have a miniature scene or a very large scene that exceeds the default settings.
Add two polygon spheres to the scene by choosing Create > Polygon Primitives > Sphere.
Leave one of the spheres at the center of the scene and place the other sphere 30 units in the negative z direction.
Add a camera to the scene (Create > Cameras > Camera).
In the top view use the Move tool (w key) to move the camera 5 units in the positive z direction.
View the scene through your new camera in the perspective view panel by choosing Panels > Perspective > Your New Camera Name.
Hold down the Option key (PC - Alt key) and left mouse drag in the perspective view to tumble the camera so you can see both spheres. Press the 5 key to view your scene as Smooth Shaded.
Open the Outliner by choosing Window > Outliner and select your camera.
Open the Attribute Editor, Camera Attributes section.
Change the Near Clip Plane value to 10 and the close sphere disappears because Maya only renders objects that are at least 10 units from the camera.
Change the Far Clip Plane to 20 and the far sphere disappears because the maximum distance that will be rendered is 20 units from the camera.
