Hi;

Please take a look at my attached files. I would like to extrude primitives on a grid randomly, but the expression doesn't work..!
I use “rand(@ptnum)” in Distance parameter of Poly_Extrude node.

Thanks.

Hi,
assign a primitive Distance Scale (zscale) attribute to your grid with some random value.
Then you can use the “Distance Scale” attribute under “Local Control” tab in your PolyExtrude node. It is a multiplier to your extrude parameter.

on the same topic, I am trying to add random rotation for each element on the polyextrude level.

Using a foreach loop I can get to the result I want, but a bit cumbersome.

On the left side, I was trying to find a way to iterate on each primitive within the expression set to Pre-Rotate parameter.
It is now currently hardcoded to "0", where I would like to iterate. Currently I get all faces with same orientation.

Thanks

Hi,

I don't think you can break down the execution of that parameter to vary for each primitive, but you can do it using a Primitive Wrangle.
