animated random blinking computer buttons. How?

I am making psuedo computers and want to animate the blinking buttons.

whats the easiest way to achieve this? is there an expression I can assign to the shader/ambience channel? or just key frame it?

Help please user added image

Hi Howard,

eh... it kind of depends how you want it to be...

with keyframeing the blinks, you get more control... you could e.g. make some controllers for the computer buttons, and then make some set driven keys for on/off... however with expressions, you can make e.g. random blinks...

as I recall Alex Alvarez talked about this last year at the 3D Festival in Copenhagen, one of the subjects was about making a light/lamp blink... I can unfortunately not remember that expression... user added image

strarup- making a controller+ set driven keys sounds like the way I will go. that way I will only have to key frame the controller.

Thanks bud!

try this:

Make a sphere, called nurbsSphere1

enter the following expression:

if (noise(frame) > 0.5)
{
setAttr "nurbsSphere1.visibility" 1;
}
else
{
setAttr "nurbsSphere1.visibility" 0;
}

the 0.5 value represents the frequency of blinking.
Values between 0 and 1.
0.9 very intermitently on.
0.1 very intintermitently 0ff

Note :

if you want light to stay on for a few frames then its a bit more tricky.
