MBOX ® MEDIA SERVER USER MANUAL 17
IMPORTANT! If the Master Intensity is set to zero (or a low level) you will not see any imagery on the output!
Note: A preference is available to force Mbox to use software dimming even when connected to the I/O Module.
(Output: Software Dimming)
Master Color
The subtractive RGB color mixing on the Master fixture works upon the final rendered image created by compositing
all layers together.
Master Audio Volume
The Audio Volume parameter masters all audio output on the server; even audio that is subject to mastering on an
individual layer through the use of Opacity as Layer Volume or supplemental Layer Volume DMX controls.
Master Control Channel and Control Selector
The Control Channel and Control Selector are used to trigger macros, enable/disable features, and to bring up the
Heads Up Displays (HUDs) on the Mbox output screens.
Master Effects
The effects on the Master fixture are pulled from the shader-based texture effects (1-200) that may be used on each
layer. The effect is applied across the entire output context (i.e., one or both outputs depending on the mode).
Note: Some shader-based effects (e.g., transparency) applied to the Master may work differently when applied to
Layers because there is nothing behind the composite image. Other effects may be incompatible with large output
resolutions.
Camera Viewpoint Controls
The Master fixture includes parameters for adjusting the standard Camera viewpoint.
With default values, the standard Camera viewpoint is located at a predetermined distance from the 3D center of the
Mbox 3D environment. The Camera is pointed directly towards the 3D center of the environment.
+ Orbit X/Y - These parameters move the Camera viewpoint in an arc centered upon the environment's 3D center.
(The camera remains pointed towards the 3D center when orbited.)
+ Dolly - The Dolly parameter moves the viewpoint towards and away from the environment's 3D center.
+ Pitch/Yaw - These two parameters tilt (up/down) and pan (left/right) the Camera's focal point, moving it from the
environment's 3D center.
+ Roll/Spin - The Roll parameter rotates the Camera viewpoint around an axis drawn through the imaginary lens of
the Camera. Spin is a continuous rotation with adjustable speed.
+ Field of View - Field of View (FOV) is analogous to setting the narrow vs. wide-angle adjustment of a lens. Rather
than just zooming the image - making it larger or smaller - FOV will also affect the perspective of objects in view.
CAUTION! The use of the 3D Projection Mapping toolset can override the standard Camera viewpoint - at which
point the controls on the Master fixture become non-functional.
