Hello !

i coded out the python script from "Houdini Technical Rigging 1".
So far it works fine.

Now, when i'm importing it into the "Basic IK" script from "Houdini Technical Rigging 3"
i'm getting the error "hou is not defined".
It says that the error is in the first script from "Houdini Technical Rigging 1"

Why is the same functionality working when called from one script but not from the other ?
