Hello!
I am currently making a plant in Houdini and I have started with a polywire in which I copy my leaves to each point.
However, I would like the leaves to scale down in size alongst the wire(the higher you go the smaller the leaves get).

This is what I got at the moment

The scale of a copied object is controlled by the attribute @pscale when found on the points connected to the right input of the CopyToPoints node.

Place an attribute wrangle in points mode before the right input and try out this code.
This assumes the points of the stem start at 0 near the ground and increase as it grows upward.

You can also use a ramp to draw a custom contour with code like this.
Remember to click the little Icon to the right of the code snippet box to auto create the ramp parameter.

Thanks, it worked!
