Try this: 0.02*noise(fc, 15, 8)+0.042
The three arguments to the noise function are (x,y,z) coordinates in a smoothly varying nose field, so at least one of them needs to be time-dependent (e.g. fc or t) so that you take a walk through the noise. Noise returns a value between 0 and 1, so you need to scale and offset it to fit your desired range. gray From: softimage-boun...@listproc.autodesk.com [mailto:softimage-boun...@listproc.autodesk.com] On Behalf Of Pierre Schiller Sent: Wednesday, September 02, 2015 4:35 PM To: softimage@listproc.autodesk.com Subject: Random expression for "noise" on Local.posy - please help Hello group. I am trying to make a Y value have a noise driven parameter directly in it´s local.posy I found out noise can do the job on the expression editor. But it only generates 1 value on 1 frame. I tried FC and end up on an error: FC noise( 15, 8, 5 ). How is the expression to be written? I want it to vary (randomly between a 0.042 and 0.062) each frame. Thanks.
