Yeah, the expression wiggle in after effects is used for randomizing values. It has 2 inputs in it's basic form: The first represents frequency and the second the value amount: wiggle(1, 25);

For instance if I wanted a camera to shake I'd apply a wiggle expression to it's Z Rotation parameter. Or if I wanted a flicking light effect I'd apply a wiggle to the opacity of an object and so on..
I just didn't know how this would translate to 3D, specially Houdini. But the Noise() and Turb() functions gave me some pretty good results.

Thank you.

Oh, okay, I've found this tutorial which explains the noise() function so I came up with this expression for the Y parameter:

noise(0,rand($PT)*$T*3,0)*2

what about fitting in a noise($TX,$TY,$TZ) ! expression into the mix

Hey thanks for the reply man. You'll have to be a little more specific in this one though, since I don't know how the noise() expression works
