SPECIAL EFFECTS
Decay
The Camera fixture includes controls for a Delay effect. Since it operates
from the Camera fixture, the decay is applied to the composite image
created by all five layers.
In the example to the right, a gobo has been given a Z-spin value and
decay has been applied.
It is important to note that Decay will only work against a background of
"nothingness." This means the absence of content (no texture or object). If
no layer is above 0% opacity, then there is only black "nothingness" (i.e.,
the absence of content). If a gobo is placed on Layer 1 and a texture is
applied, then rotate or move it with decay turned on, to see the effect.
If a gobo is placed on Layer 2, in front of a fullscreen texture on Layer 1, and then decay is turned on, no decay will be
seen.
You cannot tell that the gobo is rotating from the example image here, but it is. But no decay is visible since there is
"nothingness" behind it. However, if you reduce the opacity of Layer 1 behind the gobo, you can begin to see the
decay.
