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
example:
Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

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...

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.
