Hello, when I import a .obj from Modo I get the “shop_materialpath” as an attribute, so I wanted to turn them into group's with a wrangle node. And wrote what you can see on the attached image. Now the gettattrib and re_replace works as you can see in the Houdini Console. But when I use “currAttrib” in the setprimgroup no groups are created, and there is also no error reported by the wrangle node.

If I uncomment currAttrib = “test”; it does work so..is there someway to get this wokring or do I need a completly different approach to convert the shop_materialpath attribute to groups ?

Isn't the problem with the group name starting with number?

Try to replace like this:

pezetko

Try to replace like this:

"/shop/", "group_"

Tried that and it worked. however seems like it can be anything as long as it is not a number it starts with, so it doesnt have to be “group_”.

Thanks man, feels a bit stupied that I didnt try that hehe
