View Full Version : Equivalent of max noise controller in XSI
I often use the noise controller in max to add shake to cameras, flicker to lights ect. Is there an equivalent of this in XSI?
Thanks

Create a null, press Ctrl+K for its local transform.
Right-click on Position Y and Add Expression.
Add a Random expression from the Functions list.
To ramp it in and out, you can multiply it with a custom parameter ranging from 0 to 1, and animate that parameter.
ok, thanks.
There's some interesting stuff in there. I'll have to have a look around.
One thing though, the noise in there gives you an X Y Z variable but why would you need these 3 when you can only apply it to one animatable parameter?

Hi,
x,y,z, do not relate to the axis, but are the 3 arguements that are used to generate the noise function. Replace each arguement with an expression (even just a single value) to vary your noise function (just make sure one of the expressions involves time!).
Thanks guys, that's handy stuff!
try this one, little but handy

You can also check out an Fcurve tools plugin I wrote, it has an add noise layer option.
(xsi 6)
You select the fcruves you want to add noise layer(s) too, and in the plugin PPG, you set
the options and click the button.
