Hi everyone,

Working on feathers right now, and I notice a difference in deformation between the LOP feather procedural & the SOP feather deform.
It seems like the feather procedural isn't handling Barbs Deformation.

The result is matching when I'm setting the deform barbs parameter at 0 on the Feather Deform
Is there a way to make it work ?

Here's a basic hip scene to show the issue

Hi guys !

I've begun to learn Houdini since a few days and I can't seem to find the way to use variables in expressions.
Basically, I want to build a tower like the Leeza Soho in Beijing.
I want to do the exterior part by creating a cylinder, duplicating & shifting it in the y-axis and I want to be able to scale those cylinders by using a math expression & their copy number.
I try inputting this expression in the scale attribute of the copy node :

“−0.0004*$CY^²+0.04*$CY+1”

I believe $CY is the variable which hold the number of copies, maybe I'm wrong.
I do think it's really basic & i'm probably just dumb.
I probably isn't plug in it in the right place or maybe there's a syntax error.

Thanks for your help
