How do I get a SOP Grid with noise to animate in P(0) and P(1) as it only moves in P(2)?

How do I get a SOP Grid with sop noise to animate in P(0) and P(1)?
As it only moves in P(2) whether I add absTime to translate x ,y or z.

Im trying to get an instanced geometry to wiggle in the x and y plane only.

thanks

Ive worked this out using TOPs as the instancing OP.
But I have to say that it doesn’t make sense to not be able to do this with SOPs!

Hi @semiconductor,

the Noise SOP uses the source geometry’s normals to offset the points. One way to animate randomly in all 3 directions can be to first use a Noise SOP and set the Attribute parameter to “Point Normals”. Now follow this up with a Noise SOP with default parameters and you should see the points being transformed in all directions.
