Please see the attached toe file, on my computer tx and ty are not updating with the noise. I have changed it to Random, so, you can clearly tell, what’s being displayed in the sopto is not what’s in the noise sop.
Please help! Have a show in a couple of days, would really like to resolve this issue before then. I just ran into it today when I was building something that uses grid sop to instance geometries.
the Noise SOP applies the noisefunction to the geometry depending on the input SOPs point normals. Now as the point Normals of the default Grid SOP all point towards z, the noise is only applied to the tz position of the points - hence no change in tx and ty.
to get a fully random offset, try using 2 Noise SOPs. Set the first Noise SOPs Attribute Parameter to “Point Normals” and the following Noise SOPs attribute to “Point Position”
