I have an animated mesh that I am breaking using the primitiveSop, applying a small scale and then extruding. I need help in figuring out the correct way to put a random expression in the extrude distance so that I get a variety of extruded depth per primitive. Any help is greatly appreciated.

I don't understand your question clearly but using rand($PR) as extrude value may solve your problem

Hi,
See the attached scene file showing the sort of expression you can use

hey…thanks for pointing me in the right direction at least, everybody gets stuck sometime.

Circusmonkey thanks for the more correct and frankly nicer post.

Circusmonkey this is great.
I'm using Houdini15 and the polyextrudes look different.
How would you go about doing the same process in the new Polyextrude?

- Generate random attribute for scale: use attribute randomize sop, class: primitive, name: zscale (set to dimensions: 1 (float))
- extrude sop: Distance: 1 under Local Control enable Distance Scale: zscale
(enable Divide into Individual Elements on the polyextrude sop)
