Defining Layer Media Behaviour (How?) - Martin LIGHTING DIRECTOR User Manual

DEFINING LAYER MEDIA BEHAVIOUR (HOW?)

If you have chosen to do dynamic control of lighting parameters, the "Layer Media
Behaviour" area at the bottom of the "Layer Media" screen lets the MLD know how
you would like the parameters controlled. First, decide in which dimension you would
like to establish a relationship. The blue box on the bottom represents the three
dimensions: upstage - downstage, stage left - stage right, and floor - ceiling.

Suppose you want to increase the intensity of the light as your performer approaches
stage right. The dimension you would choose is Stage Right - Stage Left. As you click on
the Stage Right - Stage Left dimension on the cube you will go to the appropriate media
behaviour screen. At the top of the media behaviour screen there is a line of text with
numerical fields to enter. "From stage right to stage left ". Here you can
enter DMX values to define a simple linear relationship. If you type "From stage right
50 to stage left 255 " your light intensity will start off with a dimmer value of 50
when your performer is on stage right and then gradually and automatically it will go up
to a maximum of 255 when the performer reaches stage left. Of course, if the effect
you wanted was the opposite, light dimming as the performer approaches stage left, you
could enter appropriate values such as "From stage right 255 to stage left 50 ".
Under the numerical fields there is a graphical representation of the relation. The graph
maps the relationship between position or velocity in that dimension and "Media bytes",
which for lighting corresponds to DMX values. On the left you have stage right and on
the right stage left. You may draw a curve of behaviour for complex effects. An example
would be if you wanted light intensity to start low, increase to a maximum in centre
stage and then go back down as the performer reaches stage left.
