To use this camera set the 'Projection' to Perspective (default camera type).


This camera node provides a perspective view, like a regular camera. This is the 'standard' camera type that you will probably use most often. In addition to a normal perspective, this camera type also provides controls for the depth of field, and the focal length of the camera, as well as controls, to do with the aperture of the camera. This allows various camera lens effects, including bokeh, to be simulated.

You can see more information about cameras on the Camera Properties pages.


Simulates the effect of camera exposure (in a non-physical way). Increasing this parameter by a value of one gives you one stop up (doubles the brightness). 

Radial Distortion 

Radial distortion, with negative and positive values resulting in pincushion and barrel distortion respectively. Real-world lenses can show such distortion when using, for example, a very short focal length or a high zoom.

Radial Distortion (-1.3 to 1)


A 'barrel distortion' camera lens effect has been reproduced in the interior scene below, by simply increasing the Radial Distortion to 0.2 (rollover image).

Radial Distortion Type

A lens radial distortion compatible with the 3ds Max physical camera. It is selectable through persp_camera.radial_distortion_type cubic_inverse. The classic cubic type is still the default. 


Lens Tilt Angle

Controls lens tilt angles with respect to the projection plane. The horizontal and vertical angles are specified in degrees. This is useful in architectural renderings to compensate for perspective transformation for vertical lines.




vertical lens_tilt_angle: 0 to 15

Lens Shift

Shifts the lens position. This is useful to recenter the subject after using tilt. The shift is given in normalized screen coordinates: +1 will move the frame center to the right or bottom edge. Note that lens shift will affect the render in a different way than screen_window, notably with distortions or vignetting since one is a lens effect and the other just selects the part of the rendered image that will be output.  





Motion Blur

Depth Of Field

Enable Depth of Field

Enables depth of field effects.

Focus Distance

This is the distance at which objects appear in perfect focus, for a non-zero aperture value. 

Aperture Size

The radius of the aperture in world units. The smaller the aperture, the sharper the images (shallower depth of field). In the limit, a size of zero produces no depth of field blurring. 

Aspect Ratio

Values bigger than one produce an elongated defocusing effect, reminiscent of an anamorphic lens, while a value less than one will squash it.


Aperture Blades

A number of blades (or polygon sides) of the polygonal aperture. 0 is considered a circle aperture

Blade Curvature

The curvature of the polygonal aperture sides. A value of 0 means hard straight sides. Increasing this value results in progressively more curved edges, all the way to 1.0 which produces a perfect disk. Negative values produce a "pinched" or star-shaped aperture.

Aperture Rotation

Rotates the aperture by the specified number of degrees. 


Flat Field

This parameter matches the standard thin lens camera model. This prevents over blurring away from the optical axis. Some renders might change, especially with wide FOV angles or very shallow DOF. Set persp_camera.flat_field_focus false to get the previous behavior.
