Masks are used primarily for compositing.įor image formats that do not support mask channels, the mask is stored as a separate image. Black areas represent areas where there are no objects (or fully transparent objects), and white areas represent areas where there are (solid) objects. A mask is an 8-bit channel (the alpha channel) in the image file that represents objects in shades of gray. If on (and Renderable is on), the camera creates a mask during rendering. If on (and Renderable is on), the camera creates an image file during rendering. By default, Renderable is on for the default perspective camera, and off for all other cameras. If on, the camera can create an image file, mask file, or depth file during rendering that is, it is able to render. This value is used to compute a film roll matrix, which is a component of the post-projection matrix. The rotation occurs around the specified pivot point. This specifies, in degrees, the amount of rotation around the film back. This value is used to compute the film roll matrix, which is a component of the post projection matrix. This double precision parameter corresponds to the normalized scene view. Vertical pivot point used for rotating the film back. This value is a part of the post projection matrix. The pivot is the point where the rotation occurs around. The pivot point is used during rotation of the film back. The horizontal pivot point from the center of the film back. This value indicates the artificial 2D camera pan. The Film Translate value is used in 2D effects. The value is applied before the film roll. This value indicates the artificial 2D camera zoom. The Pre Scale value is used in 2D effects. Use the following MEL command to set the Shake Overscan: SetAttr perspShape.shakeOverscanEnabled 1 Use the following MEL command to turn on Shake Overscan Enabled:
By default, Shake Overscan is set to one. The Shake Overscan attribute is only used when the Shake Overscan Enabled attribute is set to true. This attribute will affect the output render. This overscan is used to render a larger area than would be necessary if the camera were not shaking. Shake Overscan specifies a multiplier to the film aperture. Shake Overscan Enabled allows the Shake Overscan attribute to be factored into the camera calculation. Use the following MEL command to set the Shake attribute: Use the following MEL command to turn on Shake Enabled: Shake provides an additional set of filmback translation inputs on the camera, with the additional feature that Shake can be turned on and off via the Shake Enabled attribute. For camera calculation purposes, Shake and Film Offset provide the exact same effect. The value is specified as a separate horizontal and vertical shake field, both of which default to zero, and are only utilized in the camera calculations when the Shake Enabled attribute is enabled. Shake specifies a translation on the filmback. Shake Enabled allows the Shake attribute setting to be factored into the camera calculation. The Shake and Shake Overscan attributes duplicate and combine functionality with the Film Offset attributes and API. The Shake Enabled toggle can be used to turn the effect of the shake on and off. A curve or expression could be connected to the Shake attribute to specify a realistic shaking effect. Use the Shake attributes to apply some amount of 2D translation to the filmback. The higher the value, the more space is outside the view guide. The edges of the view guide may be exactly aligned with the edges of the view, in which case the view guide is not visible.
