Motion Controllers
Using DMX Motion Controllers
Capture has the functionality to allow incoming DMX channels to be mapped to control the height and
rotation of objects. In these examples, we are going to look at moving truss around with DMX. The
functionality is not limited to trusses only, it can be used with most objects and forms within Capture.
There are two types of DMX Motion Controllers in Capture. The DMX Mover and the DMX Rotator.
The DMX Motion Controllers are added to a project like any other object in Capture - by dragging them from
the Library into one of the design views. Its best to look at the controllers like lighting fixtures, they are
fixtures in the project. Its good practice to place the movers near to the object they are controlling for ease of
identification and manipulation, but they may be hidden from view if required.
The DMX Mover, pictured to the right, has two blobs at each end of the range. The thicker blob indicates the
default starting point of the object the Mover is attached to. The thinner blob indicates the lowest point to
Mover operates to.
The DMX Rotator, pictured to the right, is shown here as it is seen in the “Orthographic Front” design view. The
thick blob in the middle of the circle indicates the central rotation point that the object will rotate around. The
line protruding from the centre of the circle from the blob is the default starting point. The circle itself
indicates the range in which the Rotator can operate. In this case, it is a full circle as the
Rotator has a range of 360 degrees.
Adding a DMX Mover
As we discussed, the first type of DMX Motion Controller is the DMX Mover.
The DMX Mover can move an object across a predefined range on the X Y Z axis. The mover can also be
configured to operate on only one axis, for example Y, so that the object it is attached too will only move up
and down.
Drag the DMX Mover into the project from the library. It can be found under “Motion Controllers”. Position it
near to the truss it will be linked with, this will make it easier to manage projects with multiple movers.
Select the mover and access its properties in the Project Window.
Give the mover a name, using the “Unit” field. Then configure its properties to match the ranges in which you
want to mover to operate. In this case, the X and Z range will be 0 and the Y range will be -5.8m as we only
want the mover to move the truss up and down. 5.8m is the distance between the truss and the floor.
Select the Truss and the Fixtures you wish to move and select the DMX Mover from the “Motion Fixture”
property in the Project Window.
The DMX Mover can now be selected and manipulated in the Live view just like any other fixture.
Adding a DMX Rotator
The second DMX Motion Controller is the DMX Rotator. The Rotator can be used to rotate an object around
on an axis and within a specific range on that axis.
