Anyone can help me understand how to use a custom created attribute(@windowname) on building_generator node?

Hi friends,

I recently started my first project in Houdini, using building_generator node + open street map data.
I got stuck when I tried to use a custom created attribute in Facade Module Pattern


An attribute named “windowname” is created in an attribute wrangle node. I intend to use it in Facade Module Pattern in buliding_generator node. It should assign window01 module to a group of buildings, and window02 module to the rest.


I can still see the “windowname” attribute on attribwrangle2 node before it goes into building_generator node.

But, I can't see/use “windowname” attribute on building_generator. I've checked primitive/points/vertex/detail parameters… Not existing.

My 2 questions are
1) where is “windowname” attribute on building_generator? why disappearing?
2) what is the best way to assign “windowname” to Facade Module Pattern in buliding_generator?

Thank you!
