Hi there,

Noob question here. Trying to learn about attributes.

I simply want to extrude a group of primitives using an attribute called height that I made with an attrib create node. However when i type @height in extrusion distance, nothing happens. I have to type “detail(”op:../attribcreate1“,”height“,1)” for it to work.

Shouldn't I be able to just type @height?

File included. Why does polyextrude1 work, but not polyextrude2?

Best,
Albinioni

You need to use local control for that: https://www.sidefx.com/docs/houdini/nodes/sop/polyextrude#local-control [www.sidefx.com]
Don't forget to choose individual elements, if you are extruding them as connected components I don't think you can control it via attribute.

Thank you for the reply FFD!

However I'm not sure if I understand from reading the information that you posted. From what I can understand local control are the Distance scale, Inset scale, Twist scale, and Divisions scale parameters and have nothing to do with controling them via attributes.

1) detail(“op:../attribcreate1”,“height”,1) set Result Distance = Detail Attribute(attribcreate1)
2) Local Attribute set Result Distance = Distance (field) * Primitive Attribute(attribcreate2)

Ugh...just spent quite a bit of time here only because "@height" does not work?
and to reiterate from a cross post why does it not work directly in the distance field with "@height" or "height"
