Hi!

It's a great tutorial, “Feather Ray Lift”, but I can't understand the meaning of two AttributeCreate nodes: one is after first AttributeCopy node, it creates new attribute “ray_lift” and this attribute is just a copy of “dist” attribute. And another one is second AttributeCreate node which is creates new “ray_lift” attribute and which is a copy of old “ray_lift” attribute. I've tried to use one “dist” attribute along the network and it seems that it works ok.
So what meaningful these two attributecreate sops do in this tutor?

Thanks.
